Insecticides for Control of Wireworms in Wheat

Updated May 6, 2006 by Gary Hein and John Thomas
Wireworms will feed on the roots of wheat plants and will cause significant damage only when populations are extreme.
Healthy, well-fertilized plants will outgrow wireworm damage.
Treatments would be recommended only in very high-risk situations (e.g. planting into heavily-infested sod).
