Wireworms continue to impact cereal production in Idaho. Typically we expect a reduction in wireworm activity later into the summer. This year, however, we continue to collect the insect in considerable numbers in cereal fields. Not much damage is expected at this point since wheat and barley crops are at later stages of development. Delayed growing season, and early-season rainfalls, may explain continued wireworm activity.
If you think that you might have wireworms in your field please contact us for monitoring instruction. Seed treatment and proper rotation are recommended.
Be aware of safflower susceptibility to wireworm damage. Click for information about wireworms and their management.
Late blight has been reported on-farm in Minidoka county. Molecular confirmation is in progress by the University of Idaho.
While the potato psyllids are generally low in numbers in eastern Idaho, their presence is not uncommon. However, keep an eye for any potential zebra chip disease symptoms in potato fields. The disease is not common but it has been reported from Magic Valley and Treasure Valley areas on occasions in previous years.
We have received several reports of Hessian fly infestation in Northern Idaho and Eastern Washington. Our screening program to identify sources of resistance in spring and winter wheat genotypes. These efforts are in collaboration with University of Idaho and Washington State University wheat breeding programs. Click for information about Hessian flies. Contact us for resistant PNW varieties.
