Wireworm Webinar Offered to Idaho& Washington Wheat Growers


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.

For those who cannot view the webinar in real time, it will be recorded and available at: www.idahowheat.org.

Growers’ help needed to improve crop insurance
Sprout damage from heavy rains in southern and eastern Idaho at the end of the 2014 growing season made evident the inadequacy of current crop insurance for wheat growers, which is based on yields and not quality.

USDA’s Risk Management Agency has expressed a willingness to make changes to the quality standard for wheat by addressing the low falling number scale, but the agency wants to address the issue nationwide and needs strong data to support any changes.
Growers can assist the effort by providing multiple years of settlement data, at least the last six years but preferable the last 10 to 12.

RMA does not need and would prefer not to receive growers’ names, addresses and tax ID numbers.

The data must contain: the year; county and state where the crop was grown (not sold/delivered); quality of production; gross price received; net payment (gross less any dockage, but not considering any storage or shipping fees); test weight; and protein.

In addition, the agency needs at least one of the following: DON/VOM; falling number; or other quality spec of interest.
Growers are asked to send info to Blaine Jacobson at blaine@idahowheat.org.
