2022 Dry Spring Conditions

Landscape & Garden    Treasure Valley - Idaho

Posted on: March 25, 2022 by Nic Usabel

Much of Idaho has experienced below average precipitation this past winter and it continues into early spring. The Treasure Valley is no different. During periods with low water resources, it is important to prioritize watering needs. While some lawn conditions appear dry it is not yet time to begin the watering of residential lawns. Consider the following as a prioritization to follow during times of low water resources:

• Young or newly transplanted trees which have a limited root system. Ensure to proper application of water and water deeply and infrequently based on soil texture.
• Established trees and shrubs should also be given consideration to priority watering as established plants are high value and take many years to replace. When applying water to trees and shrubs apply at an appropriate rate that allows water to soak into the soil to a depth of 12 inches. Frequency of water depends on soil texture and if water restrictions are in place. General guides are as follows: April once per month, May through September up to twice per month.
• Fruit gardens, vegetables gardens, and flowers are generally next on the list of prioritizations. Consider using a wood mulch or organic matter around trees, small fruits, and plants to reduce water evaporation from the soil. Avoid direct stem to mulch contact. Fruit trees and small berries may benefit from an early water now if soil conditions are dry. Early spring bulbs may also benefit from an early water if dry conditions are present. 
• Lawns finish out the priority list. If watering the lawn, ensure that sprinklers are operating correctly and applying water to desired location. Make water applications so that water is applied deeply and infrequently. Increase the mowing height of the grass and consider mulching the clippings versus bag removal.

2022 Rose & Grapevine Pruning

Landscape & Garden    Treasure Valley - Idaho

Posted on: March 25, 2022 by Nic Usabel

Across the Treasure Valley it’s time to prune grapevines and roses. See below for more resources for pruning these landscape & garden plants.

ROSES:

Rose pruning should occur when the buds are starting to swell in early spring. Below are a few resources that can be read or viewed for rose pruning.

• How to Prune Roses, Utah State University Extension video
• Early Spring Pruning of Roses, University of Maryland Extension video
• Guide to Pruning Roses, University of Maryland Extension
• Pruning Roses, Colorado State University

GRAPEVINES:

The University of Idaho Research & Extension Center in Parma recommends pruning grapevines in the Treasure Valley no sooner than mid-March to ensure that low temperatures do not kill buds after pruning. Grapevines can “bleed”, movement of sap from the cut, heavily when pruned in spring. This does not harm the vines. Below are a few resources that can be read or viewed for grape pruning.

2022 Spring Lawn Fertilization & Care

Landscape & Garden    Treasure Valley - Idaho

Posted on: March 22, 2022 by Nic Usabel

Spring lawn fertilization for cool season grasses recommend that fertilization be made while energy is being directed to root growth, which is followed by leaf growth. This timeframe for cool season turf in the Treasure Valley traditionally March thru early May. If mulching is a practice in your lawn maintenance plan, nitrogen can be reduced by ½ pound annually. 

The proper rate of fertilizer application is best achieved when using a soil test result to identify the fertilizer needs of the soil. UI Extension publication Using Soil Test Results for Garden Fertilization will help guide the steps.  Applications should be split between spring and fall. Application rates should not exceed 1 pound of nitrogen per 1,000 square feet in any one application, access Southern Idaho Lawns Fertilizer Guide to identify additional time(s) for application if rate would exceed the 1 pound of nitrogen per 1,000 square feet limit with only and spring and fall application. Always follow label directions.

For more information on how to obtain a soil sample to a soil test submission contact your local University of Idaho Extension office. 

Another method of identifying application rate is based on the level of turf maintenance from low to high traffic. Application rates should not exceed 1 pound of nitrogen per 1,000 square feet in any fertilizer application and always follow label directions. Review descriptions, timing, and rate of application below.

1. Light use: Classified as occasional foot traffic or little to no play from children. Annual turfgrass recommendation is 0-1 pound of nitrogen per 1,000 square feet. Split the application between a spring and fall application. 
2. Moderate Use: Typical children’s play and occasional garden parties. Annual turfgrass recommendation is 2-3 pounds of nitrogen per 1,000 square feet. Split the application equally between a spring, early fall (late September) and late fall (Mid October to Late November) 
3. Heavy Use: Frequently used sports field play, heavy traffic and/or frequent garden parties. Annual turfgrass recommendation is 4-6 pounds of nitrogen per 1,000 square feet. Apply 1 pound of nitrogen per 1,000 square feet in spring, 0.5 pound of nitrogen per 1,000 square feet late May/early June, 0.5 pound of nitrogen per 1,000 square feet late June/early July, 1 pound of nitrogen per 1,000 square feet early fall (late September) and 1 pound of nitrogen per 1,000 square feet late fall (Mid October to Late November).

If your lawn is suffering from soil compaction or development of a thick thatch layer core aeration can be completed in the spring but is preferred in fall while weed pressure will be reduced. For more information visit UI Extension publication Core Aeration of Lawns-Benefits & Procedures.

Spring provides the opportunity to seed new turfgrass areas or to over-seed areas that may have been damaged over the winter. Cool temperatures will promote germination and growth of cool season turf species, tall and fine fescues, perennial ryegrass, and Kentucky bluegrass. Weed pressure can be higher during the spring as compared to the fall when seeding or over-seeding.

If there are additional questions on lawn care or weed management reach out to a local University of Idaho Extension office.

2022 Delayed-Dormant Oil Application

Landscape & Garden    Treasure Valley - Idaho

Posted on: February 27, 2022 by Nic Usabel

In the coming weeks areas across the Treasure Valley could reach temperatures desirable for applying a delayed-dormant oil spray. The use of horticultural oil as a delayed-dormant spray can target many insect pests at a time when beneficial insects are not yet active. Use of the term “delayed-dormant” indicates that the oil should be applied after bud swell. This timeframe coincides with the increasing activity of the overwintering insect stages, such as aphid eggs, scale nymphs, and peach twig borer larvae.

The two factors of temperature and bud stage must correspond before application of horticultural oil is made.

TEMPERATURE: 

Only apply oil if temperatures remain above freezing (ideal is above 40°F) for 24 hours after application and on a clear, non-windy day in the 50 to 70°F temperature range. 

BUD STAGE: 

The window of application extends from bud swell to when the leaves just start emerging. The last point you can safely apply oil based on fruit tree crop are:

• Apple: Half-inch green, but ideal application at green tip stage. 
• Pear: Cluster bud. 
• Cherry: White bud. 
• Peach/nectarine: pre-bloom. 

Refer to the Critical Temperatures for Frost Damage on Fruit Trees by Utah State University to view images of each bud stage mentioned.

Oil should be applied at a rate of 2% (5 Tbs in 1 gallon water) and thoroughly cover all cracks and crevices. 

If aphids and scale have been a serious problem in previous years an insecticide could be added, see Chemical Control of Landscape Pests for chemical products available by pest. Read and follow label instructions for preparation and application.

If fire blight was an issue in the previous year add in a copper product for fire blight. 

If you have additional questions, contact your localUniversity of Idaho Extension office.

Cereal Leaf Beetle in Winter Wheat, Parma

Small Grains    Treasure Valley - Idaho

Cereal Leaf Beetle

Posted on: April 29, 2015 by Olga Walsh

Cereal leaf beetle infestation was identified in winter wheat experimental plots at the University of Idaho Parma Research and Extension Center as well as in surrounding grower fields in Canyon County. The typical feeding patterns, eggs and larvae have been confirmed by Dr. James Barbour, UI IPM Specialist. The first symptoms of infestation became apparent last week. Currently, most plants have at least one leaf with obvious feeding damage. The cereal leaf beetle has a variety of hosts among cereals and grasses with preference to oat, barley, wheat, rye, timothy, fescue, grain sorghum and corn. Substantial crop yield loss and quality decrease can be expected due to lost photosynthetic activity resulting from the feeding damage.
Cereal leaf beetle is a quarantined insect the U.S., which means that the presence of beetles in grain restricts exports to uninfested areas. Fumigation is required to prevent the spread of beetle infestation.
Scouting of fields is vital both before and during the boot stage to assess for cereal leaf beetle presence and damage. It is recommended to scout weekly by walking through the field in a “W” pattern for best coverage. Stop at 5-10 locations depending on field size and examine 10 plants per location. Count the number of eggs and larvae per plant for smaller plants or per stem for larger plants.
Treatment thresholds: 3 larvae per plant and/or 3 eggs per plant before boot stage, and 1 larva per flag leaf after boot stage.

Management-chemical control (From PNW Insect Management Handbook)
• bifenthrin (BrigadeÆ 2EC and WSB) at 6.4 fl oz/a (0.1 lb ai/a). Apply in spring if one or more eggs or larvae are detected or in late summer if beetles are defoliating seedling stands. Maximum amount allowed 12.8 fl oz/a (0.2 lb ai/a) per season but no more than once every 12 days. PHI 30 days prior to harvest for forage, hay and seed.
• cyfluthrin (Baythroid XL) at 0.013 to 0.015 lb ai/a. PHI 0 days. REI 12 hr. Maximum amount allowed per 5 day interval is 0.022 lb ai/a. Maximum amount allowed per crop season is 0.089 lb ai/a.
• lambda-cyhalothrin (Warrior) at 0.02 to 0.03 lb ai/a. PHI 0 days for grazing and forage, 7 days for straw and seed crop. REI 24 hr.
• zeta-cypermethrin (Mustang MAX) at 0.0175 to 0.025 lb ai/a. PHI 0 days forage, hay; 7 days straw and seed screenings. REI 12 hr. For forage and hay use no more than 0.10 lb ai/a per season; make subsequent applications no closer than 7 days. For straw and seed screenings use no more than 0.125 lb ai/a per season; make subsequent applications no closer than 17 days.

First Japanese Beetles of 2014 Caught in Boise

Announcements    Treasure Valley - Idaho

Japanese Beetle

Posted on: June 23, 2014 by Paul Castrovillo

On June 19, the first two adult Japanese Beetles (Popillia japonica) of the 2014 field season were collected in a Japanese Beetle trap in Boise. ISDA has surveyed for this aggressive invasive pest from the eastern US since 1990. In 2012, 61 beetles were caught, most in downtown Boise, indicating the beginning of a possible infestation. An eradication program was begun in Boise in 2013, and trapping that summer turned up 2,999 beetles. The eradication program is continuing this year, with insecticide treatment of 500 residential/commercial properties, most Boise Parks and several areas on the BSU campus. The first treatments were conducted in May and a second treatment is scheduled in July. Traps have been set up with a very high concentration in the city of Boise and more dispersion throughout the rest of the state to continue to survey for beetle presence and monitor location and level of beetle activity to determine areas needing treatment. The flight period of adult Japanese Beetles typically begins in mid/late June and peaks around mid July. Adults feed on over 300 types of plants including roses and fruit trees, while larvae do considerable damage feeding on grass roots in areas with lawn and turf. If any Japanese Beetles are collected in Idaho, especially outside of the Boise area, please send the dead specimens, with collection location data, to Dr. Paul Castrovillo, Idaho State Department of Agriculture, P.O. Box 790, Boise, ID 83701.

Hi folks:

Idaho State Department of Ag is conducting their unusable pesticide disposal program for SW Idaho, the last week of March. This is a program that is free to anyone who has old pesticides they wish to have “taken off their hands”. The Extension pesticide safety education program helps promote this program because it helps to prevent pesticide pollution and accidental poisoning from old pesticides that are sitting around in someone’s storage shed or garage. Please get the word out to your clientele. This is a NON-REGULATORY program offered by ISDA—it is a free service to the citizens of Idaho!!

Crop Insurance Deadlines

Tree Fruits    Treasure Valley - Idaho

Posted on: October 31, 2011 by Tony McCammon

USDA Invests in Crop Insurance Education Awarding
$651,954 throughout the Pacific Northwest

SPOKANE, Wash., October 28, 2011 - Agriculture Secretary Tom Vilsack announced today that the U.S. Department of Agriculture's (USDA) Risk Management Agency (RMA) will support crop insurance education and outreach in 47 states to ensure that small and underserved producers get the information they need to effectively manage their risk and remain productive. Awards totaling approximately $13.6 million from two RMA programs—Targeted States and the Education and Outreach programs—will support thousands of American farmers, ranchers and producers.

Of that total, $651,954 in partnership agreement awards will support crop insurance education and outreach in the Pacific Norwest Region serviced by RMA’s Spokane Regional Office. “The partnerships will provide farmers and ranchers access to a complete set of conferences, targeted instruction, strategies, and networking opportunities at a local level.” Dave Paul, Director of RMA’s Spokane Regional Office stated, "We are very excited about the diversity of these partnership agreements and believe, through these programs, many farmers and ranchers will be better equipped to address the many risk management related challenges faced on their farms and ranches.”

RMA accepted proposals from public and private entities, including colleges and universities; Federal, State, and local agencies; non-profit and for-profit organizations; and others. All partnership agreements were competitive and awarded based on merit.

The following awardees represent approved projects in the RMA Spokane Regional Office area only (representing Alaska, Idaho, Oregon, and Washington).

Northwest Center for Alternatives to Pesticides – “AGR-Lite and Farm Products Branding Training for Organic Specialty Crop Producers in Idaho” to ensure an effective program of agricultural risk management education and information through small sessions will be established in the State of Idaho that will meet the needs of its producers.

Oregon Cattlemen's Association – “Oregon Risk Management Outreach on Livestock Risk Protection Ins. and Ranch, Pasture, Range, Financial and Legal Management for Traditionally Undeserved Livestock Producers” to provide risk management outreach and education for livestock producers in Oregon who are traditionally underserved

Washington State University – “Breaking New Ground -- Using Agri-tourism as a Risk Management Strategy in the Spokane Region” to assist priority producers in the region to develop new agri-tourism enterprises that can capture additional income for producers, and help stimulate local economies. A major part of this project will be working with producers so they understand, and can mitigate both traditional risks of farming, as well as some unique new risks associated with agri-tourism.

Oregon State University – “Expanding Niche Livestock Ranching in Oregon” to strengthen risk management programming for underserved livestock producers throughout Oregon

RightRisk, LLC – “Risk Management Education for RMA’s Spokane Region: RME on Insurance, Succession Planning, Marketing, and Financial Planning to Women/New/ Hispanic/Senior/Specialty Crop/Other Producers in Idaho and Oregon” to promote sustained profitability for agricultural producers in Idaho and Oregon through effective risk management decision making.

Washington State University – “Enhancing Farming Practices and Marketing Skills as Risk Management Tools for Hispanic, Asian American, and Beginning Farmers in Washington State” to expand the successful implementation of “Cultivating Success” farm production and business management curricula with Hmong and Latino farmers in Washington.

Washington State University – “Education and Outreach Project for Producers, Ranchers, Limited Resource Producers, Ranchers, New and Beginning Farmers in Northeastern Washington, RMA Spokane District” to provide multiple learning and networking opportunities in aspects of small agriculture risk management.

Board of Regents of the University of Wisconsin System – “Delivery of Educational Materials to Increase LGM-Dairy Utilization by Dairy Farm Operators in General and Limited Resource Operators in Particular in Washington State” to develop and subsequently deliver an integrated education program composed of computer-based LGM-Dairy training workshops

Rural Community Development Resources – “Risk Planning Education for Socially Disadvantaged Farmers Sustainability in Washington State” to provide outreach and create awareness of risk management issues for SDA producers, provide individual risk planning and provide outreach to RMA regional offices in regard to the new and beginning farmers and the Center’s role within Washington State.

Institute for Washington’s Future – “Production, Financial, and Human Risk Management Outreach and Education to Hispanic Farmers in Washington State” to develop and conduct a promotional program crop insurance and other risk management tools in Spanish.

The Risk Management Education and Outreach programs are designed to help ensure that farmers and ranchers effectively manage their risk through difficult periods, helping to maintain America's robust food supply and the survival of small, limited resource, socially disadvantaged and other traditionally under-served farmers. RMA administers these partnership projects as well as the Federal crop insurance program, with funding and authority from the Federal Crop Insurance Act.

RMA helps producers manage their business risks through effective, market-based risk solutions. RMA's mission is to promote, support, and regulate sound risk management solutions to preserve and strengthen the economic stability of America's agricultural producers. Federal crop insurance provides support to American producers as part of the "farm safety net." A strong farm safety net is important to the vitality of American agriculture. Complete listings of the agreements can be found on the RMA Web site at: http://www.rma.usda.gov/aboutrma/agreements/.

Fire Blight

All Crops    Treasure Valley - Idaho

Fire Blight off Cougar blight

Posted on: May 13, 2011 by Tony McCammon

Fire Blight is forecasted for Saturday through Monday of this weekend. Cougarblight models predict high probability of infection. Infection is possible when trees have open flowers, had late season pruning, or open wounds and injured branches. For infection to occur at least two hours of moisture during 70 degree temperatures are necessary. Monitor moisture in your apples and pears. If the wetting occurs and flowers are open, apply an antibiotic such as serenade or agri-mycin. Homeowners can use blight ban or Mico-shield. If you do not choose to control fire blight at this time monitor very closely for new infections and prune them out. They usually show up within 7 to 14 days. More information to follow in Monday’s Advisory.

Powdery Mildew on organic Table grape

Small Fruits    Treasure Valley - Idaho

Posted on: September 19, 2008 by Tony McCammon

Field Day and Vineyard Tour: Managing Powdery Mildew at Rocky Fence Vineyard Saturday, September 20, 1‐3 pm, Emmett, Idaho

Presented by: University of Idaho Extension, Rocky Fence Vineyard, University of Idaho Pomology Program
Funded by: Western Sustainable Agriculture Research and Education (WSARE) 2008 Professional + Producer Grant

AGENDA
1:00 PM Welcome, registration, introductions
1:30 PM Begin facilitated vineyard tour of the powdery mildew project
2:30 PM Question and answer with grower, Extension faculty and researchers, refreshments
3:00 PM Adjourn

Organic table grape production may be a good match for southwest Idaho’s rapidly changing agricultural
landscape. Population has increased over 30% since 2000 and farms are downsizing. Producers want successful
alternative crops to diversify operations and generate income.

Michael Medes of Rocky Fence Vineyards, a producer of organic table grapes, will use this Professional + Producer

Grant to seek solutions to powdery mildew, the most threatening disease to marketable fruit. With Ariel
Agenbroad and Tony McCammon, and with the support of Dr. Esmaeil Fallahi and Dr. Krishna Mohan, they will test the effectiveness of preventive management practices, implement an expanded trellis system, scout and test for early detection and use climate‐based disease forecasting and organically approved fungicide treatments.

Project findings will be shared at two annual on‐farm demonstration events, conferences and in future Extension publications. This field day is the first of these events.

Table Grape Growers Can Learn About Powdery Mildew
Management at Sept. 20 Field Day in Emmett

EMMETT, Idaho—While organic table grapes have the potential to become a lucrative new alternative crop for small- to mid-range producers in southwestern Idaho, powdery mildew is threatening growers’ ability to harvest high-quality, marketable fruit. Most of the available information on managing this disease has been developed for growers in California, Washington and Oregon, but Treasure Valley producers can tour ongoing local research from 1 to 3 p.m. Saturday, Sept. 20, at a field day at Rocky Fence Vineyard in Emmett.

“Managing this disease is critical to the success of producers and to the sustainability of the industry,” says Ariel Agenbroad, University of Idaho Canyon County Extension educator. She and colleague Tony McCammon of Payette County and grower Mike Medes will lead a tour and hands-on demonstration of research funded by a two-year Western Region Sustainable Agriculture Research and Education Producer + Professional Grant.

Entitled “A Multi-Faceted Approach to Managing Powdery Mildew on Organic Table Grapes in Southwest Idaho,” the project’s partners include University of Idaho pomologist Essie Fallahi and plant pathologist Krishna Mohan, both located in Parma.

The free field day will be held at 3770 Fuller Road in Emmett. The tour will focus on:
• developing powdery mildew management protocols for southwestern Idaho
• trellising systems and pruning strategies for optimal air flow and operator access
• timing and materials for preventative treatment
• scouting and early detection of the disease organism
• using disease forecasting models
• timing treatments with organically approved materials
• exploring the use of composts and compost teas in fertility and disease control

Refreshments will be provided and RSVP is appreciated. For more information, call the University of Idaho’s Canyon County Extension Office at (208) 459-6003.

Sample Fruit and Tour Horticultural Research on Sept. 12
at University of Idaho’s Parma Research and Extension Center

PARMA, Idaho—On Sept. 12, Treasure Valley residents can see and taste what’s growing on the trees and vines at the University of Idaho’s Parma Research and Extension Center. Anyone interested in fruit production—including commercial growers, small-farm and alternative producers, home gardeners, hobbyists and horticultural professionals—is encouraged to attend.

Beginning promptly at 8:30 a.m., participants can nibble on new table grapes, peaches, nectarines, apples, quinces, Asian pears and other alternative fruit. They’ll learn about the use of growth bio-regulators in fruit crops before heading to the Fuji apple orchard for information on water-conserving irrigation practices, progressive pest-management, and innovative fertilization and chemical-thinning.

Then, they’ll tour experimental rows of alternative fruit crops—including quinces, Asian pears, persimmons, jujubes, haskaps and mulberries—and see a new canopy experiment in table grapes. They’ll compare varieties of peaches and nectarines and participate in a question-and-answer discussion about planting, growth regulators, pest management, pruning, thinning, girdling, irrigating and other fruit-growing practices.

The delicious event is free and slated to end at about 1 p.m. Four pesticide recertification credits will be offered.

The Parma Research and Extension Center is located about a mile north of Parma on U of I Lane. For more information, call University of Idaho pomologist Essie Fallahi at (208) 722-6701, Ext. 225, or the main office at Ext. 228.

Tree Fruit Frost Alert through Tuesday

All Crops    Treasure Valley - Idaho

Posted on: April 18, 2008 by Tony McCammon

Frost warnings that are in effect through Tuesday. Low temperatures will be dropping to the mid to low 20’s. Fruit blossoms and buds will be susceptible to losses.

See attached Table on critical temperatures for flower and bud damage.

Orchardists use heaters if available, or turn on wind machines.

Homeowners use overhead irrigation, but this can be costly. The idea is to cover the buds and blossoms with water that will freeze, forming an ice layer. Remember that water freezes at 32 degrees F, and a permanent, uninterrupted layer of ice throughout the frost period will insulate flowers and buds. The ice must remain until the daytime air temperatures rise above freezing.

The last freeze will occur 2 out of 10 years after May 4 at a temperature of 28 degrees or less in Payette County, May 6th in Emmett and Parma, May 13th in Weiser, and April 27th in Caldwell.

tree stages:

Apple Peach Cherry Apricot
Payette 1/2"green pink bud-swell bloom
Fruitland cluster pink bud-swell bloom
Parma pre-pink pink bud-swell post-blm
Emmett cluster bloom white bud post-blm
Sunnyslope cluster bloom white bud post-blm

A 10% loss of a tree’s flowers may be tolerable for some growers. They may consider it as a thinning technique this year.

As you have seen we have had a cool spring thus far and are quite a bit behind what we have been in previous years. If this keeps up it may give growers the upper hand on coddling moth this year.

Here are DD from March 1 for the past years as of April 18 AM each year in Payette. Courtesy of Bill Ford:

corn earworm

Corn    Treasure Valley - Idaho

Posted on: July 26, 2007 by Jerry Neufeld

The next generation of corn earworm moths will lay eggs in the silk of corn between 1450 and 1650 growing degree days (GDD). GDD accumulations for Caldwell, Nampa and Parma respectively are 1468, 1377 and 1464. We are accumulating about 22 to 25 GDD per day. If you have corn silking during this time you will want to continue scouting for earworm eggs.

24c Label for Beleaf

All Crops    Treasure Valley - Idaho

Posted on: July 19, 2007 by Jerry Neufeld

The section 24c label for Beleaf for control of lygus in alfalfa seed has been approved by the Idaho State Department of Agriculture. A copy of the label is available for review by clicking on “crop info”, “alfalfa seed”, and “24c label for beleaf”. and will also be available at the Idaho Department of Agriculture website in a few days.

Beleaf has been shown to be an effective lygus compound that works by preventing lygus feeding within 30 minutes of exposure. Lygus mouthparts will not be able to penetrate the plant tissue so that the insects will starve over the course of several days. Lygus on plants after treating will not damage plants or seeds. Beleaf is also very good on aphids (same mode of action), soft on natural enemies and safe to bees. Current research indicates that Beleaf can be applied at night after leafcutting bees stop foraging (more research is needed to see if Beleaf can be applied while bees are foraging). With the approval of Beleaf, we have three new tools for lygus management in alfalfa seed; Beleaf, Rimon and Assail. All three of these new compounds have modes of action that are different from each other, and from pyrethroid, carbamate and organophosphate compounds also labeled for use in alfalfa seed. Be sure to use these and other insecticides in a manner that avoids resistance development and ensures long term effectiveness. Follow label directions, don’t use the same insecticide in back to back applications and rotate between insecticides with different modes of action. Check with your supplier to see what the availability of Beleaf will be for this season. Feel free to contact Dr. Jim Barbour with questions (phone: 208.722.6701, email: jbarbour@uidaho.edu).

corn earworm

Corn    Treasure Valley - Idaho

Posted on: July 13, 2007 by Jerry Neufeld

The University of Idaho CIS 366 entitled “Timing Corn Earworm Control,”states that summer moths will begin laying eggs in fresh corn silk at approximately 1300 growing degree days (GDD). Egg hatch and larvae attack will begin about 73 GDD later.

According to the Oregon State University GDD model for Corn Earworm (http://pnwpest.org), we are currently at 1189 GDD in the Caldwell area, 1107 GDD in the Nampa area and 1185 GDD in the Parma area. We are accumulating approximately 28 GDD per day. We will hit 1300 GDD in the Caldwell and Parma areas around July 17, and hit 1300 GDD in the Nampa area around July 21. Those fields silking at 1300 GDD are most vulnerable to attack from corn earworm larvae.

The following information was taken from CIS 366 regarding corn earworm.

Corn can be “scouted” for corn earworm eggs to predict possible infestation levels. Examine 10 silk masses (about 2-day old) on each edge of a field but only in those fields which are beginning to silk or are silking. Examining a field in late silk for the first time is worthless; most of the eggs, if any were present, are already hatched, and the damage cannot be prevented.

When the egg counts average 1 per 2 masses, about 100% ear infestation will occur in the field and other fields of like maturity in the vicinity. With 1 egg per 2 silk masses, about 1 inch of each ear tip will be damaged; 1 egg per silk mass will result in about 2 inches of the ear tip damage, etc. When the days and nights are warmer than usual, the damage may double because the earworm will develop faster than the corn.

Fields should be scouted about every 2 to 4 days, depending on temperatures. Once economic egg levels are reached, determined on the basis of damage expected, further scouting is unnecessary. All fields which silk after that time in that vicinity will be subject to damage.

No chemical control will control worms in the ears, so sprays must be timed to control the larvae on the silk before the worms enter the ears. Make the first application when the plants are 50 percent silk, and repeat in 5 to 7 days or as necessary.

Iris Yellow Spot Virus

Onion    Treasure Valley - Idaho

Posted on: July 13, 2007 by Jerry Neufeld

Lynn Jensen from the Oregon State University, Malheur County Cooperative Extension Office is reporting that Iris Yellow Spot Virus has been identified in onion fields in the Fruitland/New Plymouth and Ontario, Oregon areas. There are currently no known fungicide treatment options for this virus. The virus is transmitted by onion thrips. Growers should keep their fields as stress free as possible by keeping thrips populations in check and by maintaining good irrigation practices.

assail 24c label

All Crops    Treasure Valley - Idaho

Posted on: July 3, 2007 by Jerry Neufeld

Assail 70WP (acetomiprid) has received a 24c (special local needs) registration for lygus bugs in alfalfa seed. The material is moderately effective (population suppression) on lygus and has potential as a tank is partner in cleanup or bloom sprays when lygus pressure is heavy, or as a standalone spray when lygus pressure is light and sweep counts consist largely of 1st to 3rd instars. Assail is relatively soft on parasites and predators, and safe to leaf cutting bees when applied in the evenings after the bees have stopped foraging. Assail has good activity on aphids.

stripe rust

Small Grains    Treasure Valley - Idaho

Posted on: June 21, 2007 by Jerry Neufeld

Dr. Brad Brown is reporting some stripe rust on the UI Parma R and E station in some susceptible wheat varieties. Rust was found especially in a hard red winter wheat called Moreland. It would be appropriate to scout for stripe rust in late planted winter wheat and any spring wheat if you aren’t sure of the susceptibility of the varieties to stripe rust. Depending on the growth stage, it may or may not be too late to apply a fungicide.

Coddling Moth and Cherry Fruit Fly Update

Tree Fruits    Treasure Valley - Idaho

Posted on: June 7, 2007 by Tony McCammon

As of
June 5th:                                         
Coddling Moth DD  
Biofix ACC.DD. 340dd 920dd(END Hatch)
Emmett    25-Apr 510.6    13-May 27-Jun

Larval emergence for the first generation of codling moth is 69-79% completed for Southwest Idaho. Keep fruit protected from newly emerging codling moth larvae through the projected end of the 1st generation. Currently, the codling moth model predicts that egg hatch for the 1st generation will end between June 22 and June 26. A critical period for codling moth control is 340-640 DD after biofix (first adult activity). The percentage of egg hatch (larval emergence) for the first generation changes from 12 to 80% during this period. This relatively short 300 DD window of time (approx. 10-15 days in length) will see the greatest amount of codling moth pressure. It is important to have adequate residues of insecticide present on fruit during this period. There will be a 5-7 day “break” between the 1st and 2nd generation where fruit protection is not necessary.

Based on numerous years of observation in Idaho, fruit is not susceptible to egg-laying from cherry fruit fly females until it changes from yellow to a salmon or blush color. When the earliest maturing fruit on the tree takes on a blush color, protect cherries with an insecticide application. Based on research, adult females are not ready to lay mature eggs until 7-10 days after first catch of the season. Use these two pieces of information for your location to initiate insecticide sprays to protect fruit from cherry fruit fly. Flies will develope according to temperatures like most insects. Spray timing can also be based on 190 Degree Days. Use the temperatures from the top of this page to time your applications.
Insecticides effective for WCFF:
- Spinosad GF-120 NF (apply with an electric pump sprayer mounted on a 4-wheeler; reapply every 7 days; excellent adulticide; not rainfast)
- Provado (moderate adulticide, excellent larvicide, can kill larvae within fruit; reapply every 14 days; watch for mite flare-up with repeated applications)
- Success and Entrust (reapply every 7 days)
- Dimethoate (Be careful follow instructions closely)
- Guthion (reapply every 14 days; 15 day PHI)
- Sevin (reapply every 7 days; watch for mite flare-up with repeated use)
- Diazinon (reapply every 7-10 days; 21 day PHI)
- Malathion (reapply every 3 days; watch for mite flare-up with repeated use)

Western Cherry Fruit Fly (Sweet and tart cherry): Western cherry fruit fly adults have been caught in locations of Emmett May 25th and Sunny Slope May 29th. Based on numerous years of observation in Idaho, fruit is not susceptible to egg-laying from cherry fruit fly females until it changes from yellow to a salmon or blush color. When the earliest maturing fruit on the tree takes on a blush color, protect cherries with an insecticide application.

Posted on: May 18, 2007 by Tony McCammon

I wanted to update Coddling moth Spray dates. The morning of May 15th was the 250DD or first Hatch Date for coddling moth in Fruitland, Snake River Valley, Parma, and Sunny Slope. Emmett hit first hatch yesturday morning, May 17th. Coddling moth maximum larva hatch will be between May 21 and June 10 applications of insecticide are critical during this time period. Chemical applications

eggs: Horticultural oil, Esteem, Confirm, Intrepid, Azatin

larvae: Assail, Asana, Calypso, Carbaryl, Clutch, Diazanon, Guthion, Codling Moth Granulosis Virus, Imidan, Warrior, Sevin, Malathion
*Reapply insecticides based on the residual period (i.e., protection interval) of the product used, and be sure to rotate among pesticide classes.

Western Cherry Fruit Fly Control

Method 1: Fruit Maturity
Cherry fruits are not susceptible to egg-laying by adult females until they ripen to a salmon blush in color. Green fruits will not be attacked. Consider the maturity of the ripest fruit in an orchard, not the average.

Method 2: Adult Trapping
Adult flies do not use sexual pheromones, but are attracted to certain colors and odors. Yellow sticky panel traps (Pherocon AM®) with an external bait of ammonium carbonate (AC) are a moderately effective monitoring tool; unbaited traps should not be used. Place traps in cherry orchards before the first fly is expected [750-800 degree-days (DD)]in Sunnyslope flies were seen May 10, or by mid-May. Apply the first insecticide treatment 5 - 7 days or (190 DD-May 19) after first catch (females require 5 - 7 days for ovaries to mature.

For home and commercial orchards:
• spinosad (GF-120, Success, Entrust) – reapply every 7
days
• carbaryl (Sevin) – reapply every 7 days
• malathion (Malathion) – best when used just before
harvest as it lasts approximately 3 days
• synthetic pyrethroid insecticides – reapply every 7-14 days
∙ cyfluthrin (Baythroid) – commercial use only
∙ esfenvalerate (Asana, Ortho products)
∙ lambda-cyhalothrin (Warrior) – commercial use only
∙ permethrin (Ambush, Pounce, Ortho products)

For commercial orchards only:
• imidacloprid (Provado) – reapply every 14 days
• azinphosmethyl (Guthion) – reapply every 14 days
(scheduled for phase-out by 2012 by the U.S. Environmental Protection Agency)
• phosmet (Imidan) – reapply every 14 days; do not
use on sweet cherry
• chlorpyrifos (Lorsban) – reapply every 14 days; do
not use on sweet cherry
• diazinon (Diazinon) – reapply every 10-14 days

Lygus

Alfalfa Seed    Treasure Valley - Idaho

Posted on: April 30, 2007 by Jerry Neufeld

Right now the lygus degree day model is predicting that the 1st and 2nd instar lygus populations will peak May 6. Since we are expecting a cool down by mid-weak this may get pushed back some, but you should be getting ready to check seed fields for lygus and other early season pests. Unless you are treating with Rimon alone, you should consider treating if Lygus populations exceed 4 to 5 per sweep. If you are treating with Rimon alone you should treat before large numbers of large lygus nymphs appear. If you have 8 to 10 nabids (damsel bugs) plus geocoris (bigeyed bugs) per sweep, which is not likely this time of year, you may not need to treat. Treatment recommendations (other than Rimon) can be found in the Pacific Northwest Insect Management handbook (online at: http://pnwpest.org/pnw/insects ). We have some fields in the area that show resistance to bifenthrin (Capture/Discipline, etc.), so be sure to rotate chemistries to minimize resistance problems. In fields that have bifentrin resistance problems, bifentrin will tend to work best early season.

Onion Bulb Mites

Onion    Treasure Valley - Idaho

Posted on: April 27, 2007 by Jerry Neufeld

Lynn Jensen, Potato and Onion Specialist with OSU at the Malheur County Extension Office is reporting Bulb Mites have been identified in an onion field in the Adrian, Oregon area. At least some stand reduction has occurred because of the mites.

According to the PNW Insect Management Handbook, Bulb mites are shiny, creamy white, bulbous, and about 1⁄32 inch long. They generally occur in clusters, inhabiting damaged areas under the root plate of onion bulbs or garlic cloves. They have a wide host range, feed on many kinds of bulbs, roots, and tubers, and can infest bulbs in storage or in the field. Bulb mites can survive on decaying vegetation in the field until it is completely decomposed.
Bulb mites damage bulbs by penetrating the outer layer of tissue and allowing rot organisms to gain entry. This pest is most damaging when plant growth is slowed by mild, wet weather. Bulb mites can reduce plant stands, stunt plant growth, and promote rot of bulbs in storage. On seeded onions, they can cut off the radicle before the plant becomes established.

Onion Maggot

Onion    Treasure Valley - Idaho

Posted on: April 27, 2007 by Jerry Neufeld

Lynn Jensen, Potato and Onion Specialist with OSU at the Malheur County Extension Office is reporting an Onion Maggot infestation has been found in an onion field in the Cairo production area near Ontario. Onion maggot larvae attack germinating seedlings, feeding on the developing roots and epicotyl, and can continue to feed on the expanding bulbs during later stages of growth. This results in increased rot in bulbs held in storage.

IDAHO STATE DEPARTMENT OF AGRICULTURE’S NORTH IDAHO SPRING PESTICIDE DISPOSAL PROGRAM

Collections scheduled for southwestern Idaho are safe, legal and free

NAMPA, Idaho – Southwest Idaho agricultural producers, dealers, applicators and homeowners who are storing unusable pesticides will have a safe, legal and free opportunity to dispose of them this May when the Idaho State Department of Agriculture conducts pesticide disposal collections in Canyon County and Washington County.

Participation is free for the first 1,000 pounds of unusable pesticides per participant. Anyone with unusable herbicides, insecticides, fungicides and rodenticides should bring them to the closest collection site between the hours of 9:00 a.m. and 1:00 p.m. on the date and location listed below (sorry no fertilizer, micronutrients, paint, solvents or motor oil can be accepted):

“These collections provide a mechanism for disposing of pesticides in an environmentally sound manner,” said Victor Mason II, manager of the department’s pesticide disposal and container recycling programs.

Since 1993, the Idaho State Department of Agriculture has safely disposed of more than three quarters of a million pounds of unusable pesticides. Pesticides become unusable for many reasons, including loss of potency, exposure to temperature extremes, cancellation or suspension by state or federal authorities, or growers’ decisions to change their cropping rotations or practices.

lygus bug

Alfalfa Seed    Treasure Valley - Idaho

Posted on: April 23, 2007 by Jerry Neufeld

The Lygus degree day calculator hosted by Integrated Plant Protection Center at Oregon State University and the IPM Centers - PNW Coalition (http://pnwpest.org/cgi-bin/ddmodel.pl?spp=lyg) shows that we have accumulated about 160 growing degree days (GDD) since January 1, 2007. Peak emergence of lygus bug 1st and 2nd instar nymphs should occur right around 275 accumulated GDD. This usually, but not always, occurs around mid-May and is the time monitoring for lygus bugs in alfalfa seed fields should begin. The model is currently predicting we will hit 275 approximately May 6. In 2006, we hit 275 GDD on May 15, so we are currently running about 9 days ahead of last year.

When using most insecticides, fields should be treated when numbers of lygus bugs reach 4-5 lygus bug nymphs per 180 degree sweep. Growers using Rimon as a stand-alone spray should treat as soon as early instar nymphs are detected. You can monitor degree day accumulation using the link provided above and selecting:

1) The” lygus bug [alfalfa seed]Ben Simko 2000” degree day model from the drop down box at the top of the form
2) None in the ‘Oregon, Canada, Alaska” and “Montana, Wyoming” location boxes
3) “Parma ID Agrmt” in the “Washington ,Wyoming” location box
4) “Caldwel ID” from the “Forecast”…“weather.com” drop down box
5) The defaults for the other boxes should work fine: just be sure that the start date is January 1, 2007 and the ending date covers the time you are interested in forecasting.

6) Finally, click the “Calc” near the bottom of the form. The degree day accumulation to date plus the forecast extending to whatever ending date you selected will appear in a new window. I will provide additional updates as the 275 degree day accumulation approaches.

Dr. Brad Brown from the UI Parma Research and Extension Center is reporting he has found a large number of cereal leaf beetle eggs in the first planted spring oats. Spring planted small grains are preferred by CLB over winter planted small grains. It is not too early to scout for CLB eggs as an indication of potential larvae populations.

Stripe Rust and Cereal Leaf Beetle

Small Grains    Treasure Valley - Idaho

Posted on: April 19, 2007 by Jerry Neufeld

According to Dr. Brad Brown, from the U of I Parma Research and Extension Center, most spring wheat varieties planted in the Treasure Valley have good stripe rust resistance; however, this does not preclude the need for field scouting to determine actual rust conditions in your fields. This is particularly true if you are growing a small grain variety that is not commonly grown in our area and you are not sure of its stripe rust susceptibility. Basically, it is not too early to scout for stripe rust, especially in your earliest fall planted winter grain fields. Any rust incidence should be reported to Brad at 722-6701, ext 216 or Jerry Neufeld at 459-6003.

When you are scouting for stripe rust, you should also be on the lookout for Cereal Leaf Beetle eggs. Some CLB adults are evident in local grain fields, but not in very high numbers. In his scouting Brad hasn’t found any CLB eggs yet. The egg count is what is used for a spray threshold.

Promar Insurance Feedback Sessions

Tree Fruits    Treasure Valley - Idaho

Posted on: December 7, 2006 by Tony McCammon

INVITATION TO FEEDBACK SESSIONS
ON PERENNIAL CROP INSURANCE

(Apples, Grapes, Pears, Peaches, Cranberries, and Blueberries)

USDA¡¦s Risk Management Agency has contracted with Promar International, a food and agricultural consulting firm based in Virginia, to evaluate the insurance programs for those perennial crops for which the insurable value is based on a grower¡¦s actual production history. While they are looking at all aspects of these programs, Promar has been directed to focus particularly on the adjustments made to approved yields for instances of either alternate bearing or down trending yields. Key questions include:

„Ï How often are growers¡¦ approved yields being automatically reduced by the RMA formulas that trigger these adjustments?
„Ï Have the adjustments been appropriate?
„Ï Should all of these crops be subject to adjustments for alternate bearing?

The states covered by RMA¡¦s Spokane Washington Regional Office include Washington, Oregon, Idaho, and Alaska. The insured perennial crops of interest in this region are apples, grapes pears, peaches, cranberries, and blueberries. Feedback sessions for growers, insurance providers, agents, and extension staff are being conducted in Washington and Idaho because of the concentration of growers in that state, but the sessions are open to interested parties from any of these states, and all are invited.

Feedback sessions have been scheduled as follows:

corn earworm

Corn    Treasure Valley - Idaho

Posted on: July 27, 2006 by Jerry Neufeld

The second generation of corn earworm moths will begin laying eggs in corn silking between 1450 and 1650 growing degree days (GDD). GDD accumulations for Caldwell and Parma are 1391 and 1461 respectively. We are accumulating about 25 GDD per day. If you have corn silking during this time period you will want to continue scouting for earworm eggs.

Iris Yellow Spot Virus

Onion    Treasure Valley - Idaho

Posted on: July 21, 2006 by Jerry Neufeld

Lynn Jensen from the Oregon State University, Malheur County Cooperative Extension Office is reporting that Iris Yellow Spot Virus has been identified in onion fields in the Ontario, Oregon area. There are currently no known fungicide treatment options for this virus. The virus is transmitted by onion thrips. Growers should keep their fields as stress free as possible by keeping thrips populations in check and by maintaining good irrigation practices.

corn earworm

Corn    Treasure Valley - Idaho

Posted on: July 21, 2006 by Jerry Neufeld

The University of Idaho CIS 366 entitled “Timing Corn Earworm Control,”states that summer moths will begin laying eggs in fresh corn silk at approximately 1300 GDD. Egg hatch and larvae attack will begin about 73 GDD later.

According to the Oregon State University Growing Degree Day (GDD) model for Corn Earworm (http://pnwpest.org), we are currently at 1221 GDD in the Caldwell area and 1276 GDD in the Parma area. We are accumulating approximately 24 GDD per day. Those fields silking at 1300 GDD are most vulnerable to attack from corn earworm larvae. We should reach 1300 GDD in the next few days.


The following information was taken from CIS 366 regarding corn earworm.

Corn can be “scouted” for corn earworm eggs to predict possible infestation levels. Examine 10 silk masses (about 2-day old) on each edge of a field but only in those fields which are beginning to silk or are silking. Examining a field in late silk for the first time is worthless; most of the eggs, if any were present, are already hatched, and the damage cannot be prevented.

When the egg counts average 1 per 2 masses, about 100% ear infestation will occur in the field and other fields of like maturity in the vicinity. With 1 egg per 2 silk masses, about 1 inch of each ear tip will be damaged; 1 egg per silk mass will result in about 2 inches of the ear tip damage, etc. When the days and nights are warmer than usual, the damage may double because the earworm will develop faster than the corn.

Fields should be scouted about every 2 to 4 days, depending on temperatures. Once economic egg levels are reached, determined on the basis of damage expected, further scouting is unnecessary. All fields which silk after that time in that vicinity will be subject to damage.

No chemical control will control worms in the ears, so sprays must be timed to control the larvae on the silk before the worms enter the ears. Make the first application when the plants are 50 percent silk, and repeat in 5 to 7 days or as necessary.

UI's Parma R and E Center Field Day

Announcements    Treasure Valley - Idaho

Posted on: June 27, 2006 by Jerry Neufeld

The University of Idaho's Parma Research and Extension Center will showcase its work in small grains, forages and row crops at a July 7 field day for the public.

Beginning at 9 a.m. and concluding at lunch with a sandwich meal, this year's field day will highlight ongoing studies in wheat, barley, triticale, onions, potatoes, beans and alfalfa seed. Visitors will tour trials of promising new small grains in various market classes and will hear about the effects of harvest dates on triticale and wheat forage. They will learn about fertilizer management in small grains, including fall-planted waxy spring barleys and low-phytate spring barleys.

Participants interested in potatoes will see trials of new varieties for the Treasure Valley and studies focusing on phosphorus, groundcover effects, pesticide placement and seed physiology.

Visitors will also tour research on plant spacing and available phosphorus in alfalfa seed, on seed inoculation and treatment in beans, and on neckrot incidence and control of sunscald, thrips and nutsedge in onions.

Attendance is free and lunch will be provided. The Parma Research and Extension Center is located 1 mile north of Parma on UI Road. For more information, contact Extension crop management specialist Brad Brown at (208) 722-6701, Ext. 216, or bradb@uidaho.edu.

Stripe Rust

Small Grains    Treasure Valley - Idaho

Posted on: June 23, 2006 by Jerry Neufeld

Dr. Brad Brown, Crop Management Specialist, at the U of I Parma Research and Extension Center has found very low levels of stripe rust infection in spring barley on the Parma station. He has found rust in Colter and 1550 and somewhat less in Baronesse and 451H barley. He has also found stripe rust in spring wheat. It is low enough infection, and sufficiently late that it likely will not be of consequence for production, except possibly in the most susceptible varieties that were planted particularly late.

Early and late blight forecast

Potato    Treasure Valley - Idaho

Posted on: June 21, 2006 by Jeff Miller

A total of 300 P-Days have accumulated for the Parma and Glenns Ferry areas. Research has shown that fungicide treatment for early blight is most effective when initiated at 300 P-days.

Additionally, early season weather in the Parma area has been conducive for late blight development. The University of Idaho forecast indicates a moderate probability of late blight in that area.

Powdery Mildew in Sugarbeets

Sugarbeets    Treasure Valley - Idaho

Posted on: June 19, 2006 by Jerry Neufeld

The Amalgamated Sugar Company Field Representatives (TASCO) are saying that now is the time to plan your treatments for powdery mildew in sugarbeets. While mildew has not yet been found in the Treasure Valley, TASCO Field Representatives say the modes of action of the mildew chemistries work best if treatments are applied before mildew is found in the field. TASCO is recommending mildew applications in the west end of the Treasure Valley by July 5, and applications in the east end of the Treasure Valley (Ada/Canyon County line) no later than July 10. Treatments should be made by these dates regardless of whether or not your fields are surface or sprinkler irrigated. THIS WEBSITE DOES NOT CONTAIN A REFERENCE PAGE FOR POWDERY MILDEW IN SUGARBEETS. CONTACT YOUR FIELD REPRESENTATIVE FROM TASCO FOR THEIR TREATMENT RECOMMENDATIONS.

Rimon for lygus control

Alfalfa Seed    Treasure Valley - Idaho

Posted on: June 1, 2006 by Jerry Neufeld

The following message was submitted by Dr. Jim Barbour from the U of I Parma Research and Extension Center.

Rimon® 0.83EC insecticide (novaluron; Chemtura Corp.), has received a section 24c approval for control of lygus bugs in alfalfa seed. Rimon is an insect growth regulator that controls insects by interfering with the molting process. As larvae or nymphs feed and begin to molt, the exoskeleton ruptures and the insect dies before reaching the next growth stage. Nymphs developing in eggs laid on Rimon residues are unable to hatch.

Rimon is easy on natural enemies of lygus bugs and other insect pests. It is also very easy on adult leafcutting bees. We do not yet have information on the effect of Rimon on alfalfa leafcutting bee larvae. Because of this selectivity Rimon looks like a good fit in an Integrated Management Program and may work well to keep lygus numbers low when applied during bloom.

Rimon has provided control of lygus in our field trials and has provided better seed yields than untreated control plots even when it didn’t appear to reduce lygus bug numbers. Here are a few guidelines for using Rimon.

• Scout the field so that you know the number and size of lygus bug nymphs present in your field.

• Applications of Rimon alone should only be made when low numbers of small (instars 1-3) are present in order to prevent lygus population from reaching damaging numbers, not to rapidly reduce damaging numbers of large lygus (instars 4 & 5 and adults).

• Because it is a growth regulator and slow acting, Rimon should not be used alone as a rescue treatment on fields with high numbers of large lygus nymphs and adults.

• When high numbers of adults and large nymphs are present, Rimon should be tank mixed with a traditional pesticide to lower numbers of larger instar lygus bugs and prevent development of eggs and small nymphs.

• Rimon may also control alfalfa weevil and caterpillars.

• Follow label directions. A copy of the label can be viewed or downloaded from ISDA using the following link:

http://www.agri.state.id.us/Categories/Pesticides/Documents/24c/Rimon%20on%20Alfalfa%20Grown%20for%20Seed.pdf

• I would recommend a minimum of 15 gallons per acre when ground applied even though the label allows a minimum of 5 gallons per acre.

Please let me know if you are using Rimon for lygus control this year. I would like to track the progress of fields treated with Rimon and get your input on the product.

lygus bug

Alfalfa Seed    Treasure Valley - Idaho

Posted on: May 12, 2006 by Jerry Neufeld

The current forecast is for the 1st and 2nd instar lygus number to peak on 16 May. Warm weather this weekend may move that up a bit. At any rate, next week would be a good time to start lygus monitoring activities. The threshold for lygus is 4-6 large lygus bugs (4th and 5th instars plus adults) per 180 degree sweep. Treatment options can be found in the printed or online (http://pnwpest.org/pnw/insects) editions of the PNW Insect Management Handbook.

Onion Root Maggot

Onion    Treasure Valley - Idaho

Posted on: May 12, 2006 by Steven Reddy

Poor germination and slow emergence of onions has been widespread in Washington County. There are probably several potential causes; however, onion root maggot has been identified and treated in an onion field east of Weiser. Our cool, moist spring has created ideal conditions for onion root maggot damage. Growers might want to take a second look at problem areas to see if onion maggot is involved.

sugarbeet root maggot

Sugarbeets    Treasure Valley - Idaho

Posted on: May 11, 2006 by Jerry Neufeld

Field representatives from the Amalgamated Sugar Company are reporting adult sugarbeet root maggot flies have emerged and are flying. Adult flies begin to lay eggs near sugarbeet plants 3 to 10 days after emergence. After the larvae hatch they will begin feeding on the young sugarbeets. If you haven’t applied a treatment for sugarbeet root maggot consult your crop advisor or field representative from AMSCO for treatment options.

lygus bug in alfalfa seed

Alfalfa Seed    Treasure Valley - Idaho

Posted on: May 4, 2006 by Jerry Neufeld

The current forecast is for the 1st and 2nd instar lygus numbers to peak on 20 May. We are still running very close to average, but cooler weather forecast for next week may slow things down a bit.

Remember that the lygus degree day model indicates when peak populations of first generation 1st and 2nd instar nymphs should occur, not when treatment would be necessary. The degree day model is really useful as a tool to pinpoint early season sampling efforts. Treatment decisions should be made based on lygus thresholds and the presence of susceptible stages of alfalfa when grown for seed (the presence of flowers and flower buds that contribute to seed yield). So just because lygus bugs show up doesn't necessarily mean that they will need to be treated. It just means you should be on the lookout for potential problems. You should also be on the look out for other early season pests such as the pea leaf weevil and cutworms, especially in new seedings.

If you want to know more about degree days or to monitor degree days yourself, go to the "OSU On-Line Phenology and Degree Day" web page at: http://ippc2.orst.edu/cgi-bin/ddmodel.pl?spp=lyg. Select the lygus bug [alfalfa seed] Ben Simko 2000 model (or any other model you might be interested in) in the drop down box at the top of the page. Don't mess with the calculator mode settings, but do select the start and end dates and locations that are appropriate for you then hit the calculate button at the bottom of the page. You should get a print out of the degree day accumulations for the times selected and, at the bottom of the page, a graph of the data selected along with a graph showing the historical average for the same time.

Posted on: April 25, 2006 by Jerry Neufeld

Dr. Brad Brown from the U of I Parma Research and Extension Center was scouting a Cereal Leaf Beetle insectary yesterday and found a few CLB flying and signs of adult feeding on the leaves. He also found eggs on about 5% of the plants. The eggs were in early spring planted oats and not in adjoining winter oats that were further along in development. It is not too early to scout for CLB eggs as an indication of potential populations of the larvae.

lygus bug in alfalfa seed

Alfalfa Seed    Treasure Valley - Idaho

Posted on: April 20, 2006 by Jerry Neufeld

Dr. Jim Barbour, Research Entomologist with the U of Idaho at the Parma R and E Center provided the following information about lygus bug in alfalfa seed.

Degree days, also known as heat units or thermal units are the accumulation of temperature over time. Usually degree-days are only counted above a lower temperature threshold and below an upper threshold. Degree-days are used in agriculture and natural resources management to predict events and time management activities, such as when to sample or control a pest problem. In alfalfa seed we can use degree day units to predict the occurrence of peak populations of 1st and 2nd instar lygus bugs hatching from eggs laid by overwintering adult lygus. This event takes right at 272 degree days. On average we reach 272 degree days about mid-May, but there is considerable year-to year variation. Right now we are sitting at 78 Degree Days. That's just about right on the historical average for this time of year and well below last year when we were at 177 degree days on this date (about the time it started raining and didn't stop for a month). The forecast is for the 1st and 2nd instar lygus number to peak on 21 May, but stay tuned for more information.

Remember that the lygus degree day model indicates when peak populations of first generation 1st and 2nd instar nymphs should occur, not when treatment would be necessary. The degree day model is really useful as a tool to pinpoint early season sampling efforts.

Pesticide Disposal in Canyon County

Announcements    Treasure Valley - Idaho

Posted on: September 16, 2005 by Jerry Neufeld

NEWS RELEASE

ISDA ANNOUNCES FREE PESTICIDE DISPOSAL PICKUP AT CANYON COUNTY LANDFILL

(BOISE) Agricultural producers, dealers, applicators and homeowners who are storing unusable pesticides will have a safe, legal and free opportunity to dispose of them on September 23, 2005 when the Idaho State Department of Agriculture conducts an unusable pesticide collection. The event is being held in conjunction with Canyon County’s 3rd annual Household Hazardous Waste collection at the Pickles Butte Landfill, 15500 Missouri Ave., Nampa, in rural Canyon County.

Participation is free for the first 1,000 pounds of unusable pesticides per participant. Anyone with unusable herbicides, insecticides, fungicides and rodenticides should bring them to the collection site on September 23.

Additionally, on September 24, Canyon County residents will be able to dispose of household quantities of hazardous wastes including fertilizer, micronutrients, paint, solvents, or equipment motor oil.

Both collections will take place between 9 a.m. and 2 p.m.

“This is a great opportunity for disposing of potentially harmful chemicals in an environmentally sound manner,” said Victor Mason II, manager of the department’s pesticide disposal and container recycling programs. “These chemicals will be collected, rather than dumped down a storm drain or tossed in the landfill.”

Since 1993, the Idaho State Department of Agriculture has disposed of more than 600,000 pounds of unusable chemicals. Pesticides become unusable for many reasons, including loss of potency, exposure to temperature extremes, cancellation or suspension by state or federal authorities, or growers’ decisions to change their cropping rotations or practices.
Assistance and other information about the collection is available at: http://www.agri.state.id.us/Categories/Pesticides/pdp/indexdisposalmain.php

Corn Earworm

Corn    Treasure Valley - Idaho

Posted on: July 29, 2005 by Jerry Neufeld

According to the Oregon State University Growing Degree Day (GDD) model for Corn Earworm (http://pnwpest.org) we are currently at approximately 1110 GDD in the Treasure Valley. Summer moths will begin laying eggs in fresh corn silk at approximately 1300 GDD. The GDD model is predicting egg hatch will begin on August 4. Those fields silking at this time are most vulnerable to attack. University of Idaho CIS 366 entitled “Timing Corn Earworm Control” states that “no chemical control will control worms in the ears, so sprays must be timed to control the larvae on the silk before the worms enter the ears. Make the first application when the plants are 50 percent silk, and repeat in 5 to 7 days or as necessary.”

Posted on: July 19, 2005 by Jerry Neufeld

According to the Oregon State University Growing Degree Day (GDD) model for Corn Earworm (http://pnwpest.org) we are currently at 941 GDD in Caldwell and 954 GDD in the Parma area. We are currently accumulating about 22 GDD each day. First generation summer moths will begin laying eggs in fresh corn silk at approximately 1300 GDD. Eggs will hatch a few days after reaching 1300 GDD and the larvae will then begin feeding on the ears. Those fields silking after 1300 are most vulnerable to attack.

The GDD model is predicting we will reach 1300 GDD on July 31 or August 1 and that earworm eggs will begin hatching about August 4 or 5 in both the Parma and Caldwell areas respectively. As we approach the start of egg hatch you will want to step up your field scouting and take the appropriate control measures to treat the larvae before they enter the corn ears.

Stripe Rust in Small Grains

Small Grains    Treasure Valley - Idaho

Posted on: June 16, 2005 by Jerry Neufeld

Dr. Brad Brown, Cereals Specialist with the U of Idaho at the Parma Research and Extension Center is reporting that stripe rust in spring grains is developing quite rapidly and we are approaching the growth stages that limit spray options. According the to “2005 PNW Plant Disease Handbook,” Headline and Quadris are the only products that can be used to the ”end of flowering” growth stage. In order to maximize yields in cereals it is important to protect the flag leaf from infection.

According to Dr. Brown, the most susceptible soft white spring cereals in the variety trial at the Parma R and E Center are Penewawa, Treasure, White Bird and Jubilee. If you are growing these varieties and haven’t yet scouted your fields, you should do so as soon as possible.

Onion Thrips

All Crops    Treasure Valley - Idaho

Posted on: June 6, 2005 by Jerry Neufeld

According to the UC Davis IPM Website (http://www.ipm.ucdavis.edu/PHENOLOGY/ma-onion_thrips.html), over-wintering adult thrips lay eggs in the tissue of plants in the spring. The subsequent generation of onion thrips become adults at about 323 growing degree days. We reached that threshold a few days ago. Right now, both adults and nymphs are being found in onion fields. You should scout your fields now to determine the extent to which you have these pests because thrips populations must be kept in check early to prevent further damage when the onions move into the bulbing stage. If you are one of the growers using drip irrigation and have had success applying Vydate through the drip system now is the time to do so again. For growers using furrow irrigation now is the time to scout your fields and make treatments as necessary.

Stripe Rust

Small Grains    Treasure Valley - Idaho

Posted on: May 31, 2005 by Jerry Neufeld

Recent weather conditions in the Pacific Northwest have been favorable for the development of stripe rust in small grains. Dr. Brad Brown, Cereals Specialist with the U of Idaho at the Parma Research and Extension Center is reporting that small amounts of rust have been found in spring wheat and barley at the Parma Station. In addition, rust has been found in grower fields in the Parma area. The rust infestation in the varieties planted at Parma was minor and would not require control with a fungicide. Most spring wheat varieties planted in the Treasure Valley have good adult plant stripe rust resistance; however, this does not preclude the need for field scouting to determine actual rust conditions in your fields. That is particularly true if you are growing a small grain variety that is not commonly grown in our area and you are not sure of its stripe rust susceptibility.

Cereal Leaf Beetle

Small Grains    Treasure Valley - Idaho

Posted on: May 31, 2005 by Jerry Neufeld

Ben Simko, Entomologist with the Idaho State Department of Agriculture has been conducting field work related to Cereal Leaf Beetle at the U of I Parma Research and Extension Center. Ben is reporting that adult CLBs are still mating and laying eggs. In addition, several instars of CLB larvae are finally starting to appear. The cool rainy spring weather we had probably stretched out and flattened the egg hatch peak and subsequent larval instar phenology. This year we haven’t experienced a sharp and distinct CLB egg hatch. Therefore, scouting on spring grain hosts is still recommended over the next couple weeks to assess population levels and potential yield loss.

As of today, peak numbers of 1st and 2nd instar lygus are predicted to occur early next week (May 15). You can keep track of degree day accumulations using the OSU web site (http://ippc2.orst.edu/cgi-bin/ddmodel.pl?spp=lyg). Use degree day accumulations as a queue to start lygus scouting activities. Early season lygus threshold is 4-5 lygus nymphs or adults per 180 degree sweep.

Cereal Leaf Beetle

Small Grains    Treasure Valley - Idaho

Posted on: May 6, 2005 by Jerry Neufeld

Phil Allison from Landview Fertilizer, Inc is reporting that significant numbers of adult cereal leaf beetles and eggs are being found in grain fields south and east of Nampa. Adults are small beetles about 1/4 to 3/8 inch in size, with a metallic blue head and wing covers, red pronotum, and yellow-orange legs. Eggs are never laid in clusters, but are deposited singly or in rows of up to three or four close to the mid rib on the upper leaf surface of hosts. Eggs can hatch in 4- 23 days depending on the temperatures. Larvae are yellow to yellow-brown with a dark mass of slimy fecal material on their backs. Both adults and larvae feed on leaves. Feeding causes a characteristic stripping of the leaves. Economic thresholds are three larvae or eggs per plant, or one larva per flag leaf.

Posted on: May 2, 2005 by Jerry Neufeld

According to a representative from Amalgamated Sugar Company, growing degree day models indicate that adult sugarbeet root maggot flies will begin their spring emergence and begin flying in the very near future. Adult flies will lay eggs near sugarbeet plants. After the larvae hatch they will begin feeding on the young sugarbeets. AMSCO representatives have not seen any adult flies yet, but warn they will be flying any day now. Look for these pests to appear in the western end of the Treasure Valley first. If you haven’t applied a treatment for sugarbeet root maggot, now is the time to do so. Consult your crop advisor or field representative from AMSCO for treatment options.

Lygus

You can keep track of degree day accumulations using the OSU web site (http://ippc2.orst.edu/cgi-bin/ddmodel.pl?spp=lyg). Use degree day accumulations as an indicator of when to start lygus scouting activities. The early season lygus threshold is 4-5 lygus nymphs or adults per 180 degree sweep.

Onion Bulb Mite

Onion    Treasure Valley - Idaho

Posted on: April 22, 2005 by Jerry Neufeld

Charlie Robinson with Western Farm Service in Parma is reporting that onion bulb mites have been found in onion fields southwest of Caldwell. In one case there is an estimated 30% stand loss. The mites were positively identified by U of I Extension Pathologist Krishna Mohan. Dr. Mohan said that with the wet/cool weather we have been having, a stand loss such as that caused by the mites can be confused with ”damping off.” He warns that if you are experiencing onion stand loss, it may not be “damping off” it may be bulb mites. Positive identification of mites needs to be made by using a microscope to examine either undecayed vegetation from the field or the onions. Fields that have a history of bulb mite problems, or onion fields with undecayed vegetative matter are more prone to these pests. No treatment thresholds exist and there are no in-season treatments available. Preventative soil fumigation treatments can help to control this pest.

Cereal Leaf Beetle

Small Grains    Treasure Valley - Idaho

Posted on: April 14, 2005 by Jerry Neufeld

The cereal leaf beetle larval hatch will start in the very near future. Brad Brown from the U of I’s Parma Research and Extension Center has found adults on the ground. He has seen a few adults in flight. In addition, Landview Fertilizer field representatives have seen a few adults in grain fields south of Nampa. As temperatures warm up we can expect to see the adults become very active.

Adult Cereal Leaf Beetles will lay eggs in winter grains first. However, as spring grains (oats, barley, wheat) grow larger, the beetles will move to spring grain fields because they are the preferred hosts. Adults are small beetles about 1/4 to 3/8 inch in size, with a metallic blue head and wing covers, red pronotum, and yellow-orange legs. Eggs are never laid in clusters, but are deposited singly or in rows of up to three or four close to the mid rib on the upper leaf surface of hosts. Eggs can hatch in 4- 23 days depending on the temperatures. Scouts should be looking for adults and eggs at this point and not the larvae. Larvae are yellow to yellow-brown with a dark mass of slimy fecal material on their backs. Both adults and larvae feed on leaves. Feeding causes a characteristic stripping of the leaves. Economic thresholds are three larvae or eggs per plant, or one larva per flag leaf.

Cutworms

Representatives from Amalgamated Sugar Company are reporting they have found a few sugarbeet fields around the valley that are being damaged by cutworms. Weedy spots and field borders are typically “hot spots” for these pests.

Cereal Leaf Beetle

All Crops    Treasure Valley - Idaho

Posted on: April 14, 2005 by Jerry Neufeld

The cereal leaf beetle larval hatch will start in the very near future. Brad Brown from the U of I’s Parma Research and Extension Center has found adults on the ground. He has seen a few adults in flight. In addition, Landview Fertilizer field representatives have seen a few adults in grain fields south of Nampa. As temperatures warm up we can expect to see the adults become very active.

Adult Cereal Leaf Beetles will lay eggs in winter grains first. However, as spring grains (oats, barley, wheat) grow larger, the beetles will move to spring grain fields because they are the preferred hosts. Adults are small beetles about 1/4 to 3/8 inch in size, with a metallic blue head and wing covers, red pronotum, and yellow-orange legs. Eggs are never laid in clusters, but are deposited singly or in rows of up to three or four close to the mid rib on the upper leaf surface of hosts. Larvae are yellow to yellow-brown with a dark mass of slimy fecal material on their backs. Both adults and larvae feed on leaves. Feeding causes a characteristic stripping of the leaves. Economic thresholds are three larvae or eggs per plant, or one larva per flag leaf.

Posted on: April 12, 2005 by Jerry Neufeld

Brad Chambers from Pioneer Hi-Bred is reporting that cutworms and pea leaf weevils are starting to show up in new stands of alfalfa seed. Adult pea leaf weevils are grayish brown, slender weevils about 5 mm long, with a short snout. Adults chew notches out of alfalfa leaflet margins and sometimes can defoliate new seedling alfalfa causing serious stand loss. First reports of damage were in the Wilder area, but both pests have been found in the Nampa area also.

lygus bug

All Crops    Treasure Valley - Idaho

Posted on: March 17, 2005 by Jerry Neufeld, information provided by Jim Barbour

Degree days, also known as heat units or thermal units are the accumulation of temperature over time. Usually degree-days are only counted above a lower temperature threshold and below an upper threshold. Degree-days are used in agriculture and natural resources management to predict events and time management activities, such as when to sample or control a pest problem. In alfalfa seed we can use degree day units to predict the the occurrence of peak populations of 1st and 2nd instar lygus bugs hatching from eggs laid by overwintering adult lygus. This event takes right at 272 degree days. On average we reach 272 degree days in about mid-May, but there is considerable year-to year variation. Last year, for example, we had a very warm year and reached 272 degree day units on April 27, a bit more than two weeks ahead of the mid-May average. If you were thinking it has been warm this winter you're right. For the period beginning January 1, 2005 and ending today (March 17, 2005), we are are at 52 degree day units. That's about about 12 degree day units more than the same time period last year. If things don't cool down a bit we will be reaching peak lygus numbers even earlier this year than last.

Remember that the lygus degree day model indicates when peak populations of first generation 1st and 2nd instar nymphs should occur, not when treatment would be necessary. The degree day model is really useful as a tool to pinpoint early season sampling efforts. Treatment decisions should be made based on lygus thresholds and the presence of susceptible stages of alfalfa when grown for seed (the presence of flowers and flower buds that contribute to seed yield). So just because lygus bugs show up early doesn't necessarily mean that they will need to be treated early. It just means you should be on the lookout for potential problems. The warm weather means that other insects, such as the pea leaf weevil and cutworms could be making an early appearance as well, so be on the lookout for these as well, especially in new seedings.

If you want to know more about degree days or to monitor degree days yourself, go to the "OSU On-Line Phenology and Degree Day" web page at: http://ippc2.orst.edu/cgi-bin/ddmodel.pl?spp=lyg. Select the lygus bug [alfalfa seed] Ben Simko 2000 model (or any other model you might be interested in) in the drop down box at the top of the page. Don't change with the calculator mode settings, but do select the start and end dates and locations that are appropriate for you then hit the calculate button at the bottom of the page. You should get a print out of the degree day accumulations for the times selected and, at the bottom of the page, a graph of the data selected along with a graph showing the historical average for the same time.

Cull Onion Disposal in Idaho

Onion    Treasure Valley - Idaho

Posted on: March 2, 2005 by Jerry Neufeld

Below is a Press Release from Micheal E. Cooper, Chief of the Bureau of Feeds and Plant Services at the Idaho State Department of Agriculture. The Press Release deals with the disposal of cull onions. For additional information on this subject, click on the “Crop Info” button on the left side of the TVPestAlert.net home page. Then click on “Onion” and finally “Cull Onion Memorandum.”


FOR IMMEDIATE RELEASE
February 25, 2005

DEPARTMENT OF AG REMINDS THE ONION INDUSTRY OF THE CULL ONION DISPOSAL FOR ONION MAGGOT CONTROL


BOISE, Idaho --- We are expecting it to be a big year for cull onions. The market was depressed to the point that many fields were never harvested are there are a lot of onions still in farm and commercial storage. March 15th is the deadline for disposal of cull onion piles in Ada, Canyon, Gem, Payette, Owyhee and Washington Counties, according to rules of the Idaho State Department of Agriculture (ISDA). Mike Cooper, Chief, Bureau of Feeds and Plant Services, Division of Plant Industries, ISDA said the potential for damage to Idaho's onion crop is the basis for the regulations." The larval stage of the onion maggot attacks and destroys portions of the onion bulb providing an avenue for fungi and bacteria to cause bulbs to rot during storage. With consecutive years of wet springs, the insect has been known to destroy 80% to 90% of the crop. We frequently find the onion maggot in cull onion piles."

According to state rules, cull onions – those not useable for human consumption or deemed waste - must be disposed of by March 15th of each year or within one week of sorting after March 15th. Trucks transporting onions should be covered to prevent spillage along roadsides. Such spilled onions create good breeding sites for the onion maggot.

A civil penalty of up to $1,000 per violation has been in effect since 2000. There are also new disposal methods such as dumping, feeding, composting, spreading, chopping and shredding. The University of Idaho “Best Management Practices” for the dumping or pit disposal of culls is referenced in the rules and is available through the University of Idaho Extension Service.

The onion maggot adult flies emerge in April and May and are attracted to the volatile odors given off by sprouting onions and new seedlings. The onion maggot can destroy up t two dozen seedlings during its two week life span, so damage to a field can be substantial. If not properly disposed of, culls serve as breeding and egg-laying sites for the adult flies.

A copy of the cull onion disposal rules, as well as other ISDA rules, can be obtained from the State of Idaho Homepage at:

http://www.state.id.us/adm/adminrules/rules/idapa02/02index.htm.

Double click on the cull onion disposal rules numerical designation of 02.06.17 and download it to your computer. You will need a copy of Acrobat 3.0 or better to read it. See the instructions at the top of that Web page to obtain a free copy of Acrobat.

Cooper said the regulations have been in effect for several years and the program is working well. "We have received excellent cooperation from the onion industry. Let us continue to work together to protect Idaho’s onion industry.

PRE-REGISTRATION NO LONGER REQUIRED FOR PESTICIDE DISPOSAL
Collection scheduled for southwest Idaho is safe, legal and free

BOISE, Idaho – Agricultural producers, dealers, applicators and homeowners who are storing unusable pesticides will have a safe, legal and free opportunity to dispose of them this October 22nd when the Idaho State Department of Agriculture conducts an unusable pesticide collection in conjunction with Canyon County’s 2nd annual Household Hazardous Waste collection. Both collections will take place at the Canyon County Landfill located at Pickles Butte.

Participation is free for the first 1,000 pounds of unusable pesticides per participant. Anyone with unusable herbicides, insecticides, fungicides and rodenticides should bring them to the collection site between the hours of 9:00 a.m. and 2:00 p.m. (Sorry no fertilizers, micronutrients, paints, solvents or motor oil can be accepted. These will be collected in household quantities on October 23rd during the Canyon County’s Household Hazardous Waste Collection).

“This collection provides a mechanism for disposing of pesticides in an environmentally sound manner. The unusable pesticides collected in October will be incinerated or otherwise destroyed. Plus, Canyon County is hosting its 2nd annual Household Hazardous Waste Collection. This collection gives the homeowners of Canyon County an opportunity to properly dispose of hazardous materials that they may have as well.” said Victor Mason II, manager of the department’s pesticide disposal and container recycling programs.

Since 1993, the Idaho State Department of Agriculture has disposed of more than half million pounds of unusable pesticides. Pesticides become unusable for many reasons, including loss of potency, exposure to temperature extremes, cancellation or suspension by state or federal authorities, or growers’ decisions to change their cropping rotations or practices.

powdery mildew in sugarbeets

Sugarbeets    Treasure Valley - Idaho

Posted on: July 12, 2004 by Jerry Neufeld

Powdery mildew has been positively identified by Amalgamated Sugar Company Representatives in sugarbeet fields in the western Treasure Valley, Wilder and Star areas. In addition, black bean aphids and loopers have been found in several sugarbeet fields around the county. An insecticide for aphids and loopers can be tank mixed with a fungicide to treat both pests at the same time.

Laredo is not available this year to treat powdery mildew in sugarbeets. U of Idaho Sugarbeet Specialist Dr. John Gallian is recommending that you do not use chemicals with the same mode of action more than once a year on the same sugarbeet fields. In addition, Dr. Gallian is recommending the addition of 5 pounds of sulfur to each treatment in order to fight resistance. Contact your AMSCO field representative if you have any questions.

Amalgamated Sugar Company Field Representatives are saying that now is the time to be considering your treatment plan for powdery mildew in sugarbeets. While mildew has not yet been found in the Treasure Valley, the modes of action of the mildew chemistries work best if treatments are applied before mildew is even found in the field. Dennis Searle, AMSCO Agronomist is recommending mildew applications in the west end of the Treasure Valley by July 5 and applications in the east end of the Treasure Valley no later than July 10. Dennis says that treatments should be made by these dates regardless of whether or not your fields are surface or sprinkler irrigated. Also, loopers and other worms are being found in sugarbeet fields. Be on the look out for these pests. In many cases an insecticide can be tank mixed with your mildew treatment. CONTACT YOUR FIELD REPRESENTATIVE FROM AMSCO IF YOU HAVE ANY QUESTIONS.

soybean rust in beans

Dry Beans    Treasure Valley - Idaho

Posted on: May 5, 2004 by Jerry Neufeld

Following is information provided by Melodie Putnam of the Oregon State University Plant Clinic.

Soybean rust is an exotic pathogen that is not established in the continental U.S. It has recently moved north of the equator, and is currently in Brazil, Argentina and Paraguay. Like other rust diseases (such as wheat rusts), this disease can move long distances in air currents, and is expected to reach the U.S. soon.

Why should we in the West care about soybean rust? Because it also goes to yellow sweet clover (Melilotus officinalis), vetch (Vicia dasycarpa), lupine (Lupinus hirsutus), green and kidney bean (Phaseolus vulgaris), lima and butter bean (Phaseolus lunatus) and cowpea or backeyed pea (Vigna unguiculata). Soybean rust can cause severe defoliation and loss of yield in susceptible crops. Therefore, early detection is essential.

Soybean rust is a Federal quarantine status pathogen, but there are no plans for eradication of infected crops. Instead, it has been shown that once an infestation of soybean rust is detected, if early enough, effective control can be obtained with carefully timed fungicide applications. Detection early in the season with properly timed application of fungicides appears to present the best alternative for controlling soybean rust in the United States. It is particularly important to limit the spread of this disease, due to its destructive potential.

Please be alert to the possibility of this rust moving into bean, lupin and other susceptible crops. For more information on soybean rust, including a list of hosts and photographs of symptoms, see http://www.aphis.usda.gov/ppq/ep/soybean_rust/.

Oregon growers should contact the OSU Plant Clinic for information on how to proceed if soybean rust is suspected in their crops. Please contact:

Lygus bug

Alfalfa Seed    Treasure Valley - Idaho

Posted on: May 5, 2004 by Jerry Neufeld

According to the lygus bug degree day model we should be seeing peak numbers of 1st and 2nd instar lygus nymphs from the 1st generation lygus hatch right now. We are a full 10 -14 growing degree days ahead of average this year depending on your location. The 1st generation lygus hatch usually peaks in mid-May. Now is a good time to scout your fields and determine your treatment needs. With the continued heat insect growth will be rapidly proceeding. Check your fields at least once a week if possible, more if you are approaching the threshold of 4 lygus per sweep. Small instars (1, 2, & 3) are easier to control than large instars (4 & 5) or adults. Bigeyed bugs, damsel bugs and minute pirate bugs are also out early so watch for these beneficial insects. If the population of bigeyed bugs plus damsel bugs is twice the number of lygus bugs, and your lygus numbers are not increasing, you may not need to treat.

Lygus Bug in Alfalfa Seed

Alfalfa Seed    Treasure Valley - Idaho

Posted on: April 14, 2004 by Jerry Neufeld

Jim Barbour from the U of I Parma Research and Extension Center is reporting that the warm weather this spring has resulted in rapid lygus bug development. He is already seeing a few 1st and 2nd instars in alfalfa seed at the Parma R & E Center. The Lygus Degree Day Model (http://ippc2.orst.edu/cgi-bin/ddmodel.pl?spp=lyg) is predicting peak 1st and 2nd instar lygus nymphs from 1st generation lygus near April 29. This is about two weeks earlier than usual (last year’s date was May 23) and could change if the weather cools. Set back operations should lower lygus bug populations a bit, but it’s a good idea to be on the lookout for them. Jim has seen some predators, nabid bugs, minute pirate bugs, and bigeyed bugs early as well.

Lygu Bug in Alfalfa Seed

All Crops    Treasure Valley - Idaho

Posted on: April 14, 2004 by Jerry Neufeld

Jim Barbour from the U of I Parma Research and Extension Center is reporting that the warm weather this spring has resulted in rapid lygus bug development. He is already seeing a few 1st and 2nd instars in alfalfa seed at the Parma R & E Center. The Lygus Degree Day Model (http://ippc2.orst.edu/cgi-bin/ddmodel.pl?spp=lyg) is predicting peak 1st and 2nd instar lygus nymphs from 1st generation lygus near April 29. This is about two weeks earlier than usual (last year’s date was May 23) and could change if the weather cools. Set back operations should lower lygus bug populations a bit, but it’s a good idea to be on the lookout for them. Jim has seen some predators, nabid bugs, minute pirate bugs, and bigeyed bugs early as well.

Cereal Leaf Beetle

Small Grains    Treasure Valley - Idaho

Posted on: April 12, 2004 by Jerry Neufeld

Brad Brown from the U of I Parma Research and Extension Center is reporting considerable Cereal Leaf Beetle adult feeding and also CLB eggs in the New Plymouth area in fall planted triticale. He is also finding CLB eggs and adult feeding on spring oats in the Parma area. Feeding is more severe on spring planted oats than on the fall planted barley. Small grain producers should be scouting for the adult feeding and eggs to get some idea of the larvae populations to expect when the larvae emerge from the eggs. The egg threshold is three per plant including all the tillers on the plant. Images of eggs can be found on the CLB reference page.
