Cereal Leaf Beetle
Small Grains Treasure Valley - Idaho
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.
Potato cyst nematode in eastern Idaho

Posted on: April 21, 2006 by Jeff Miller
An ealier alert posted today erroneously reported that potato cyst nematode was easy to control and that it caused little damage to the potato crop. This was misleading. Potato cyst nematode can cause serious yield reductions in potato. Additionally, control can be difficult for various reasons.
Information on the status of this problem will be forthcoming as more solid data becomes available.
Potato cyst nematode in eastern Idaho

Posted on: April 21, 2006 by Jeff Miller
The potato cyst nematode has been confirmed in Idaho from a tare dirt sample in eastern Idaho. The confirmation did not come from plant material. Further work is underway to learn more about the source of this potential source of the soil sample. This nematode is not particularly difficult to control, and does not cause extensive crop damage. The problem is that the nematode is a quarantine pest. All official information concerning this finding can be found at:

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. 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 they 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 change the calculator mode settings, but do enter 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 period.

UC Statewide Integrated Pest Management Program releases pest management guide for potatoes
Growers and pest management professionals can now find the latest integrated pest management guidance for the potato tuberworm, a new, troublesome pest in the Pacific Northwest, in Integrated Pest Management for Potatoes in the Western United States, 2nd Edition.
The tuberworm has been recorded in California since 1856, and several times in the last 20 years it was found in the Columbia Basin of Oregon and Washington. However, it was not a major concern for growers in the Pacific Northwest until 2002, when a field with severe potato tuberworm damage was documented in Oregon. The pest is difficult to control and over the years, many farmers have relied extensively on the use of insecticides to control it.
Tuberworm is just one of many pests described in the updated IPM manual by the University of California Statewide IPM Program. Growers can find information on diagnosis and treatment for more than 120 potato pests and disorders—ranging from black scurf, which causes superficial damage, to late blight, which can destroy a whole crop. The guide includes 51 new color photos (bringing the total to 210), 58 tables and line drawings, a section on organic potato production, and a comprehensive index.
Protecting potatoes from insect infestations and diseases is essential to the production of a high-quality crop. The manual contains a new section on general predators and extensively revised sections on aphid management and virus transmission, leafhoppers and phytoplasma transmission, late blight, bacterial early dying, necrotic strains of Potato Virus Y, black dot, silver scurf, and using cover crops for nematode management. Included in the new edition are information on testing Colorado potato beetle populations for insecticide resistance, and a detailed discussion of differential host tests for identifying root knot nematode species and races.
Forty university researchers and Cooperative Extension specialists from across the West contributed to making this revision an up-to-date and essential reference for potato growers and pest management professionals.
More information on the potato tuberworm is also available on the UC Statewide IPM Program’s Web site at http://www.ipm.ucdavis.edu/PMG. Look under “potatoes.”

Stripe Rust in Small Grains
Small Grains All Locations
Posted on: April 11, 2006 by Jerry Neufeld
Recent weather conditions in the Pacific Northwest are once again favorable for the development of stripe rust in small grains. Diana Roberts, PhD, Area Extension Agronomist with Washington State University predicted stripe rust presence from a forecasting model based on winter temperatures. The results were presented by Scott Yates in his article “Rust Expected to Hit Later This Year” in the Capital Press (February 24, 2006). The forecast results indicate that stripe rust will likely develop on susceptible varieties as severely as last year.
Although the forecast model indicates as equally severe stripe rust for 2006 as it was in 2005, Dr. Roberts says the disease will most likely start at least 2-3 weeks later in 2006. This is because of the following two factors. First, due to the lack of moisture last fall during planting time many winter wheat fields were planted in late October. The late plantings should have reduced stripe rust infection before the winter. Second, the cold weather last December prevented further development of stripe rust during the winter months. The cold period in mid February has further slowed winter wheat growth and should have also slowed rust development in infected plant tissue. Therefore, based on the forecast model and these considerations, we will likely have another severe stripe rust year in the PNW. The disease will start later than last year and the damage should not be as great as last year because the initial rust pressure will not be as high in 2006 and the growth period for stripe rust development will be shorter. However, stripe rust is capable of quickly developing and spreading if temperatures and moisture conditions are favorable. Recent Treasure Valley weather conditions were similar to those used in Dr. Robert’s stripe rust prediction model.
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. According to Dr. Brad Brown from the University of Idaho’s Parma Research and Extension Center, it is not too early to scout your earliest fall planted winter grain fields for this disease. In addition, Dr. Brown expects later planted spring wheat will be the most susceptible to stripe rust in 2006.

NRCS Cost sharing for biofumigation and field scouting
Announcements All Locations
Posted on: November 8, 2005 by Jerry Neufeld
The Natural Resources Conservation Service has approved two pest management practices for EQIP cost sharing. Producers must sign up by NOVEMBER 22, at their local NRCS Field Office.
The two Pest Management practices are:
1. Biofumigation. This is the planting of either radish or mustard as a green manure crop preceding potatoes or sugarbeets. The crop is planted following an early harvest crop such as wheat. Trials conducted in 2003 and 2004 show biofumigation costs the farmer about $120 to $140 per acre. Farmers using biofumigation have seen significant decreases in nematode populations and increases in potato yields, without using chemical fumigants. The practice will pay a flat rate of $50/Ac and is limited to a maximum of 160 acres.
2. Field Scouting. It was agreed that NRCS needs to promote the use of field scouting for insects to determine if threshold numbers are exceeded prior to making the decision to apply pesticides. This practice is limited only to insect pests -- not weeds. The scouting must be done by a qualified (certified) individual (likely a crop consultant or CCA). Submission of scouting and insecticide records will be required. This practice will pay $10/Ac and is limited to 160 acres.
Producers should contact their County NRCS Field Office by NOVEMBER 22 and sign up to participate in an EQIP contract. After the signup, NRCS will contact interested producers and work with them to develop an EQIP contract. These two pest management practices will be part of their contract along with other conservation practices they may be interested in.
Potato Tuberworm
Potato All Locations
Posted on: October 14, 2005 by Jerry Neufeld
Potato tuberworm, also commonly called the tuber moth, is a relatively new pest of concern in the Pacific Northwest. Several tuber moths were recently collected near Parma in a trapping system established by the University of Idaho with funding from the Idaho Potato Commission. The Idaho State Department of Agriculture has responded by developing a more extensive set of traps throughout southern Idaho. While we don’t yet know what these isolated findings of tuberworm adults in Idaho mean, we do know that tuberworm damage if left unchecked can reduce the value of a potato crop more drastically than just about any other pest. Therefore, it is important that growers and fieldrepresentatives stay informed about this pest and focus on the best management practices that have been established for the control of potato tuberworm. Background information on the pest and results of the University of Idaho trapping program are available at http://www.uidaho.edu/so-id/entomology/. Best management practices and general information on potato tuberworm can be found at www.agri.state.id.us/Categories/PlantsInsects/RegulatedAndInvasiveInsects/Insectsformreports.php#Potato. Results of the Idaho trapping network are scheduled to be posted at that website in the near future. Information on tuber moth trap counts for the Columbia Basin of Washington and Oregon can be found at www.potatoes.com/mapthing/plotmap1.cfm. This information was provided by Dr. Mike Thornton from the University of Idaho.
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
