unsable pesticide collection
Announcements All Locations
Posted on: October 11, 2002 by Jerry Neufeld
ISDA conducts unusable pesticide disposal collection from agricultural producers, dealers, homeowners and applicators throughout the state. Although pre-registration was required in the past, it is not required this year. Prospective participants need only bring their unusable pesticides to the Canyon County landfill from 9:00 a.m. to 1:00 p.m. on Wednesday, October 23, 2002. ISDA 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 or animal exposure. This program provides the agricultural producer and homeowner a safe, convenient, and environmentally friendly way to dispose of unusable pesticides. This program is free for the first 1,000 pounds of unusable pesticides per participant. Contact Victor Mason Agricultural Program Manager at ISDA if you have questions (465-8442).

corn earworm
Corn All Locations
Posted on: August 19, 2002 by Jerry Neufeld
Earworm in sweet corn seed has been a problem in the Treasure Valley this summer. The third generation was estimated to emerge at about 1450 to 1650 growing degree days (August 3 to August 15). Fourth generation emergence can?t be predicted with the current GDD model; however, it usually appears in late August to early September. Keep up your scouting program for this pest.
Western Yellowstriped Armyworm
Alfalfa none
Posted on: August 7, 2002 by Steven Reddy
Western Yellowstriped Armyworm has been reported in new seeded, second cutting alfalfa east of Weiser. Numbers have been high enough in some fields to cause defoliation and have required treatment. Armyworms rest at night but can be seen feeding and moving during the day.

Posted on: July 29, 2002 by Jerry Neufeld
The next generation of corn earworm moths will begin laying eggs in the silk of corn between 1450 and 1650 growing degree days (gdd). In Nampa/Caldwell and Parma we are currently at 1389 and 1390 gdd respectively. The Oregon State University IPM model is predicting we will hit 1450 gdd in Nampa/Caldwell on August 2 and in Parma on August 1.
Corn Blotch Leafminer

Posted on: July 29, 2002 by Jerry Neufeld
A new corn pest, the corn blotch leafminer (Agromyza parvicornis), was discovered last week in a northeastern Idaho field near Rigby. To the best of our knowledge, this is the pest?s first occurrence in Idaho, although it has been reported previously in Southeastern and Midwestern states and, in 1995, in Nebraska. The current scientific literature indicates that corn is its only known host plant. Click on the "More Information" button for additional information and images.

Posted on: July 23, 2002 by Jerry Neufeld
Numerous corn earworms are being found in sweet corn fields south of Lake Lowell and between Nampa and Caldwell. Worms are in the tassels and silk. Worms in the tassels are probably the first generation. Worms in the silk are probably the second generation. Infestations are severe enough to require treatment. Information provided by Producer's Supply Coop.
Iris Yellow Spot Virus in Onions
Onion All Locations
Posted on: July 23, 2002 by Brad Geary
Iris Yellow Spot Virus symptoms are becoming very prevelant in onion fields where the symptoms were not obvious a couple of weeks ago. Once the virus is in the plant, minimize damage by reducing stress - particularly water stress. Fungicides will not control viral pathogens, so do not apply fungicides unless you are targeting a fungal pathogen.
cereal leaf beetle
Corn none
Posted on: July 16, 2002 by Jerry Neufeld
Large numbers of adult cereal leaf beetles are being found in sweet corn seed fields that border spring wheat fields. Beetles seem to concentrate on corn plants that are under stress. Thanks to Fred Butler for this information.

Greg Willison, Chiquita Farms (New Plymouth) has been observing adult CLB infestations and feeding damage in field corn. Damage is most severe in corn fields adjacent to small grains, especially small grains that were not treated for CLB.
Adult CLB infestations of field corn are rarely of economic significance. However, growers may become alarmed at the amount of damage, especially near the field borders. The following web address links to a publication from Virginia Tech that has a section on CLB in field corn: http://ipm-www.ento.vt.edu/nipmn/VA-IPM/cereal_leaf_beetle/clb.html. In that publication it says:
"Adults emerge as the small grain crop is drying and migrate to other areas to find suitable food. Often, corn fields bordering small grain fields are attractive to the migrating beetles and these adults colonize the corn, especially along the edges nearest small grain. Cereal leaf beetles eat the leaf surface tissue on whorl stage corn plants. Narrow streaks are eaten between the leaf veins, usually on the surface but sometimes completely through the leaf. If beetle populations are very high, defoliation can reduce yield, but leaf feeding is usually cosmetic. Damage is often alarming to farmers even if it poses no economic threat. Beetles do not reproduce or remain for a very long time in corn fields and, therefore, damage is a single, short-term event that rapidly developing corn plants soon out-grow."
There has been rare case of economic damage of CLB in field corn in the eastern U.S.
corn earworm
Corn All Locations
Posted on: July 15, 2002 by Jerry Neufeld
Second generation corn earworm moths will begin laying eggs in the silk of corn that is silking at about 1300 growing degree days (gdd). According the Oregon State University gdd model, we are at 1032 gdd in Nampa/Caldwell and 1032 gdd in Parma. We are accumulating about 23 gdd per day. The model predicts we will be at 1300 gdd about July 25, 2002.
There is a possibility that a few overwintering or first generation moths may be laying eggs in the silk right now. However, the greatest threat will come from the second generation moths. You will want to scout your fields and take control measures as needed.

Powdery Mildew in Sugarbeets
Sugarbeets none
Posted on: July 9, 2002 by Jerry Neufeld
Agronomists from the Amalgamated Sugar Company have found Powdery Mildew in sugarbeet fields in the Ontario area. If you are planning to apply a preventative treatment for Powdery Mildew you may want to scout your fields for Black Bean Aphid prior to the treatment. Both treatments can be applied together if necessary. If more than one treatment per year is used, remember to alternate active ingredients since powdery mildew can build up chemical resistance quickly.
Black Bean Aphid in Sugarbeets
Sugarbeets none
Posted on: July 9, 2002 by Jerry Neufeld
Black Bean Aphids have been found in sugarbeet fields south of Nampa in numbers requiring treatment. Aphids can be found in the center of the whorl of sugarbeet leaves. This information provided by Landview Fertilizer.

Powdery Mildew on Potatoes
Potato none
Posted on: June 27, 2002 by Lynn Jensen
Powdery mildew was positively identified on a red potato variety from a garden in Ontario. This early for powdery mildew to infect potatoes. Potatoes grown under furrow irrigation, in particular are at risk and should be treated with a protectant, either sulfur or Quadris (or both).
Onset of Lygus Hatch in Alfalfa Seed Observed
Alfalfa Seed none
Posted on: June 26, 2002 by Ben Simko
At the U of I, Parma Experiment Station, Jim Barbour and I are conducting alfalfa seed insecticide efficacy research using Capture + dimethoate as a standard “clean up” treatment as well as evaluating the performance of some newer chemistries. At the Monday, June 24th, 14 days post treatment sweep counts, we are detecting a big hatch of small 1-2 instar Lygus nymphs (20-30/sweep) in the station plots. The onset of this first bloom period hatch is confirmed in other areas by Lynelle Drake’s, Andrews Seed Co. scouting program. Growers and seed company fieldmen are advised to begin regular sweep sampling to survey fields for this hatch and begin planning for their bloom period insecticide treatments. Proper timing of these bloom sprays is critical to maximize control of Lygus infestations using our limited set of bloom insecticides.
Corn Rootworms
Corn none
Posted on: June 25, 2002 by Jerry Neufeld
Corn Rootworm larvae have been found in several field corn fields south of Kuna. Larvae will feed on root hairs and tunnel into the roots for about a month before they reach maturity. Adults feed on tender portions of the plant, especially pollen and silks. Thanks to Jim Hipwell from Bio Flora Northwest for providing this information.
