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.

Sugarbeet powdery mildew has been identified in the Magic Valley near Filer, Idaho, today (7/23/07) by Amalgamated Sugar Company fieldmen Nic Wittman and Dave Scantlin. Dr John Gallian confirmed the diagnosis. Growers in the
area are advised to begin their powdery mildew spray programs to minimize economic loss.
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.
Green peach aphids
Potato Magic Valley
Posted on: July 10, 2007 by Jeff Miller
A report was received today from a consultant that green peach aphids were seen in a couple of potato fields. Now would be a good time to intensify the scouting of fields. The best place to look is at the edge of fields on nightshade plants.
Spotted alfalfa aphid
Alfalfa Magic Valley
Posted on: July 10, 2007 by Dale Baker
Glenn Shewmaker has reported a sighting of spotted alfalfa aphid in the Mini-Cassia area. Growers need to scout carefully. This species can kill seedling stands and decrease yields in established fields.

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.
