Alfalfa Seed Treasure Valley - Idaho
Posted on: May 16, 2003 by Jerry Neufeld
Mike Huff from Dairyland Seed is reporting that 1st and 2nd instar lygus have been found in alfalfa seed fields in the Homedale area. A few ahpids (~10-15 sweep) are also being found.
Onset of First Lygus Bug Hatch in Alfalfa Seed
Alfalfa Seed Treasure Valley - Idaho
Posted on: May 15, 2003 by Ben Simko
Lygus bug degree-day model, through May 13, indicates Ontario and Parma areas have accumulated 220 and 238 degree-day units respectively. Peak first hatch (1st & 2nd instars) is predicted at about 275 degree-days and the current forecast indicates peak hatch to occur on or near May 20-22. Temperature regimes experienced this spring compared to last year (2002) show similar hatch dates. In 2002 the peak hatch occurred around May 18. Jim Barbour and I have observed small nymphs
( mostly 1 and 2 instars) at the U of I Parma Experiment Station alfalfa seed test plots. Traces of floral buds are starting to also show in some established fields.

Sugarbeet Root Maggot
Sugarbeets Treasure Valley - Idaho
Posted on: May 13, 2003 by Jerry Neufeld
According to the growing degree day model for sugarbeet root maggot developed by Dr. Ed Bechinski from the U of I, peak flight of maggot flies will occur in the next few days. Shortly after emergence the flies will lay eggs in the soil next to the sugarbeet plants. Larvae that hatch will then begin feeding on the sugarbeet taproot. Representatives from the Amalgamated Sugar Company say that if you haven?t yet applied a treatment for sugarbeet root maggot, now is the time to do so. Consult your crop advisor or field representative for treatment options.
Stripe rust in Wheat
Small Grains Treasure Valley - Idaho
Posted on: May 9, 2003 by Jerry Neufeld
Stripe rust has been found in wheat in Connell WA and Pendleton OR at levels not seen in years. Brad Brown from the UI Parma R and E Center has not seen stripe rust in western Idaho as yet, but he is starting to take a closer look. Brad says "Most of our current varieties have good adult plant resistance but we should be on the lookout nonetheless." Stripe rust flourishes in continued cool rainy weather with wind. We have had some environmental conditions conducive to this pest. Whether it becomes a serious issue for western Idaho remains to be seen but we should be vigilant.
Cereal Leaf Beetle Larval Hatch Starting
Small Grains Treasure Valley - Oregon
Posted on: May 8, 2003 by Ben Simko
Cereal Leaf Beetle (CLB) larval hatch is just beginning in spring grains near Adrian, OR and in winter wheat near Fruitland, ID. Adults, eggs and a few 1st instar larvae were observed in preferred hosts of spring barley but also in Brundage variety winter wheat. CLB counts collected in a Steptoe barley field near Adrian had average egg numbers at 3 per plant. A winter wheat field near Fruitland had average egg levels at 0.8 per stem or tiller. Based on thresholds established in eastern US production areas the barley field has reached an economic threshold but the winter wheat is at sub economic levels at this stage. Fieldmen and growers are advised to monitor populations of CLB and the larval hatch to assess potential economic damage to grain crops. See CLB Reference Page for more information on identification, action thresholds and crop protection chemicals. USDA APHIS staff are looking for a fields in Oregon for potential biocontrol release site of beneficial CLB parasites. For more information contact the Malheur County extension office at 541.881.1417.
Pea Weevil
Peas Treasure Valley - Idaho
Posted on: May 7, 2003 by Jerry Neufeld
Phil Allison from Landview Fertilizer is reporting heavy infestations of Pea Weevils in seed pea fields southeast of Nampa. Chewing on leaves has been observed. It is important to control adults before they lay eggs on the pea pods. Once eggs are laid it is too late to prevent weevily seeds.
Spider Mites in Mint
Mint Treasure Valley - Idaho
Posted on: May 7, 2003 by Jerry Neufeld
Terry Drye from Simplot Company is reporting low levels of Two Spotted Spider Mites in mint fields in the Star area. At the present time the number of mites does not require treatment. However, fields are being monitored in the event the mite numbers grow to the point that treatment is needed.
Pea Leaf Weevil
Alfalfa Seed All Locations
Posted on: April 22, 2003 by Jerry Neufeld
Brad Chambers from Pioneer is reporting Pea Leaf Weevils are being found in spring seeded alfalfa seed fields. Insects have been found around Caldwell, Nampa, and Melba. Brad is reporting these insects have been around for a few weeks and he has seen stand reductions in fields with high populations. Pea Leaf Weevils feed on the cotyledons of the seedling after it emerges and then on older growth. Leaves with half circle notches in them should alert the grower that they are present (they can be confused with cut worm damage). 2003 Insect PNW is reporting there are no products registered for this pest.
Cereal Leaf Beetle Seminar
Announcements none
Posted on: April 21, 2003 by Ben Simko
A special seminar is schedule for noon, Tuesday, April 22 at the OSU Malheur County Extension Office, Ontario. The topic will be Cereal Leaf Beetle Biology and Management Update. Two factors may contribute to increasing infestations and control decisions relative to this new small grains pest. One is the general dispersion and increase of the insect in the western Treasure Valley region over the last few years. Another factor for concern is that with limited irrigation water supplies many producers are replacing row crops with spring wheat and barley. These are favored host for this pest.
Please join us for an informal session at our office. Bring your own lunch, drinks and share question and ideas for management of CLB. Mike Cooper, IDA entomologist, is also planning to attend and will give an update on CLB bio-control efforts in SW ID.
ISDA pesticide disposal program
Announcements All Locations
Posted on: April 21, 2003 by Jerry Neufeld
Here is information from Victor Mason at ISDA regarding pesticide disposal in the Treasure Valley.
April 21, 2003
To: PESTICIDE USERS IN IDAHO
RE: PESTICIDE DISPOSAL PROGRAM (PDP)
The Idaho State Department of Agriculture (ISDA) is preparing for the annual unusable pesticide collection programs in your area this spring. Since 1993, when the pesticide disposal program (PDP) began, it has safely disposed of over a half a million pounds of unusable pesticides.
Collections are going to be held in: Caldwell - May 19,2003; Weiser- May 20, 2003; Lewiston ? May 21, 2003, and Coeur d' Alene ? May 22, 2003. All collection times are from 9:00 AM- 2 PM.
This program is specifically designed with the agricultural pesticide user in mind; however, we accept pesticides from virtually all sources including farmers, homeowners, pesticide applicators, researchers, or pesticide dealers, etc. We include herbicides, rodenticides, fungicides, insecticides and all other "icides" in our definition of pesticides, however, we are unable to accept fertilizers, spent motor oil, antifreeze, paint or similar waste in these pesticide collections. There is no cost to the participant for the first 1,000 pounds of pesticide. We would appreciate your promoting the program to other pesticide users in your area.
The department is not concerned with who has what pesticide, since the program is simply a service provided by the department to prevent possible contamination of the environment or avoid potential human and animal health exposure. Although pre-registration prior to collection will not be required it will be necessary for the participants to sign a release, transferring the ownership of the products to the ISDA at the collection site in accordance with the PDP rules.
It is the responsibility of the participant to follow all Federal and state laws and rules pertaining to the transportation of these materials and to over-pack all torn or leaky containers to prevent a release of product into the environment during transportation. ISDA staff is available to provide assistance in over-packing torn or leaking containers provided that sufficient time is available for arrangements to be made prior to the collections (the sooner the better).
The WEB Page address for the program is http://www.agri.state.id.us/agresource/pdptoc.htm
Local ISDA staff is also available to answer any questions you may have about these collections. The phone numbers and office addresses can be obtained by calling the Boise office at (208) 332-8610, or if you or anyone has questions, I can be reached by phone at (208) 465-8442 or E-mail at vmason@agri.state.id.us

Victor Mason II, Agricultural Program Manager
Cereal Leaf Beetle
Small Grains All Locations
Posted on: April 15, 2003 by Jerry Neufeld
Brad Brown, UI Extension Crop Management Specialist, and Bob Trudel from Producers Supply Coop are both reporting they have seen cereal leaf beetle adults and adult feeding damage in small grains. Brad saw the adults and feeding damage approximately two miles east of Wilder.
Overwintering adults become fully active (mating and flight) when daytime temperatures reach 66 degrees F. Adults mate and begin to lay eggs on host plant leaves within 10 days of breaking diapause (spring emergence). Preferred hosts are spring seeded small grains, especially oats and barley. Eggs take from 4 to 23 days to hatch depending on temperature. Upon emergence, CLB larvae will begin feeding on host leaves.
Welcome and Thanks

Dear Pest Alert Subscriber;
As you already know, crop pests are appearing in the Treasure Valley. We have already posted a couple of alerts. Seems like the pests show up earlier each year.
Based upon the comments received in last year?s evaluation, the 2002 TVPestAlert.net operations were a success. With your help, we posted 51 alerts to approximately 195 subscribers in the Treasure Valley. Below are several comments received from subscribers on last fall?s evaluation:
Ø The alfalfa seed, corn, onion, and sugarbeet pest notifications helped me decide when to scout my fields and helped me to improve the accuracy and timing of my pesticide applications. (Grower).
Ø I used it to assist the crop advisors in watching what pests were coming into our area. I know the hatch information was of particular interest to the crop advisors and growers when they were trying to time spray applications. (Simplot Company Field Representative)
Ø Made me more alert to the possible danger of a certain pest or disease. I didn't have any major pest problems because through pest alert I caught them in time. (Grower)
The primary crops of Pest Alert subscribers are small grains, onions, corn, sugarbeets, forage, alfalfa seed, potatoes and mint. Presently, 38% of subscribers are growers, 35% are field representatives, 20% are government and 7% are other. There are currently 226 subscribers.
TVPestAlert.net wouldn?t be possible without our sponsors. Last year?s, and this year?s sponsors include the Idaho Alfalfa and Clover Seed Commission, the Sugarbeet Research Commission and the Idaho Potato Commission. We would like to extend a sincere thank you to them for their generous support.
As you can see from the comments above, TVPestAlert.net is a valuable service to the agriculture industry in the Treasure Valley. We would like to thank each of you who contributed to that success by submitting pest information last year. As we proceed through the 2003 growing season, please don?t forget to submit pest information to us. In addition, please tell your neighbors, or clients about the website.
Once again, thanks to everyone who helped to make TVPestAlert.net a success. We wish each of you a safe and prosperous production season.
Sincerely,
Jerry Neufeld, UI

Cutworms are increasing in numbers in alfalfa seed fields throughout the Idaho portion of the Treasure Valley and also in the Nyssa/Adrian area of Malheur county. Populations in the Parma, Wilder, Homedale, Nampa and Melba areas have been on the increase over the last week. New alfalfa seedings small enough to be affected by this pest should be inspected and if necessary proper treatment should be applied to avoid serious stand reduction. Brad Chambers from Pioneer provided this information.

To all Potato Growers:
POTATO GROWERS MEET TO DISCUSS FRY CONTRACTS.
All contract potato growers for the Idaho fry processing companies are encouraged to attend one of two meetings this week to discuss the current state of contract negotiations for the 2003 crop year. Meetings have been scheduled for 1:30 p.m. at the Burley Inn on Thursday, February 27 and 1:30 p.m. at the Shilo Inn Suites in Nampa on Friday, February 28. The Southern Idaho Potato Cooperative reports that meetings held to date with Idaho fryers indicate soft french fry demand which means a decrease in the amount of Idaho potatoes required for frozen processing. With no fry contract settlements to date in the Pacific Northwest and planting time rapidly approaching, growers should take a hard look at their options for displaced contract potato acreage.
