Alert Details

Corn rootworms will continue to cause problems in scattered fields all across the corn-growing region, but especially those that were planted late or are taking longer to mature where fresh silks are still available for consumption. Fields at the greatest risk at this time are located in the upper Midwest and Great Lakes region from the Dakotas east into Minnesota, Wisconsin, and Michigan. All fields in the corn-growing region, however, should continue be monitored for beetle populations as any known beetle problems now may signify a problem in that same area in 2014 if not treated now. Fields from northeast Colorado, northern Kansas, Nebraska, eastern North and South Dakota, Minnesota, Iowa, northern Missouri, central and northern Illinois, Wisconsin, Michigan, Indiana, Ohio, Michigan, and southwest Ontario, Canada are all at risk either now or if not treated where needed, next growing season.
