Codling Moth Larval Emergence Date
Tree Fruits Treasure Valley - Idaho
Posted on: May 5, 2004 by Tim Davis
As of today May 5th we are currently any where from 150-185 degree-days for the Codling Moth. This range depends on when your biofix was set and the area you are in. The model is predicting larval emergence (250dd) any where from May 12-15 again depending on you local temperature and biofix date. The Fruitland/Payette area is on the earlier end of the prediction as it has been a bit warmer here this year. The Caldwell area is on the later end of this prediction. Plan your cover sprays accordingly and DONT BE LATE!
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.

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.
Cereal Leaf Beetle
Small Grains Treasure Valley - Idaho
Posted on: April 7, 2004 by Jerry Neufeld
Brad Brown, UI Crop Management Specialist, is reporting that adult cereal leaf beetles are beginning to emerge and have begun flying around the western Treasure Valley of Idaho. Overwintering adults begin flying and mating when daytime temperatures reach 66 degrees F. Egg laying on host plants will take place within about 10 days of emergence. Preferred hosts are spring seeded small grains, especially oats and barley. Eggs take from 4 to 23 days to hatch depending on temperature. Scouting for eggs early will give you an idea of the damaging larval population you can expect in May.
Sugarbeet Root Maggot
Sugarbeets Treasure Valley - Idaho
Posted on: April 7, 2004 by Jerry Neufeld
Dennis Searle, Agronomist with AMSCO is reporting that due to the warm weather we are running about 10 growing degree days ahead of last year. This means that very soon overwintering root maggot pupa will begin emerging as adults and begin flying. In 2003 the peak capture of maggot flies was about May 13 in the Caldwell vicinity according to the sugarbeet root maggot growing degree day model developed by Dr. Ed Bechinski from the U of Idaho. In 2004 the same model is predicting peak capture of maggot flies on about April 22. Dennis thinks we will see flies flying within about 10 days, and maggots feeding on sugarbeets by the end of April. 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.
