The Idaho Wheat Commission and the Washington Grain Commission will be presenting a web-based grower education seminar (webinar) on wireworm identification, damage and solutions.
The webinar will be approximately one hour. Participation is simple and free! Log onto the website at http://connect.cals.uidaho.edu/wheat (requires Adobe Flash Player which is installed on most computers) and enter your name as a participant.
Friday, February 24, 8:00 a.m. MST – Guest Presenter Aaron Esser, Washington State University Extension will update participants on the latest research, scouting methods and appropriate grower response to the pest.
Wireworm populations and crop damage have been increasing in wheat (Triticum aestivum L.) production across eastern Washington and Idaho. Today nearly all spring cereal crop acres are treated for wireworms with neonicotinoid insecticides such as Cruiser® (thiamethoxam) or Gaucho® (imidacloprid). Neonicotinoids are toxic to wireworms but at sub-lethal doses, or in other words they repel or provide only seedling protection.
The webinar presented by Mr. Esser will focus on how to improve grain yield and profitability under wireworm pressure and reduce wireworm populations in the soil.
Esser will discuss his research on a series of large-scale on-farm tests (OFT) which were initiated in 2008 examining varied rates of Cruiser insecticide and a series of OFT examining a very high labeled rate of Gaucho insecticide to reduce wireworm populations in the soil. A series of small plot insecticide treatments have also been initiated examining multiple products with potential for control.
