Alert Details

Corn rootworm hatch and emergence is expected to continue across virtually the entire corn-growing region in the next five days. Fields from eastern Colorado into the Dakotas, Nebraska, Kansas, Missouri, Iowa, Minnesota, Wisconsin, Michigan, Illinois, Indiana, Ohio, and southwest Ontario, Canada are all at risk. Emergence is most likely along and south of I-80 but some beetles have been reported further north in Wisconsin this week so growers should continue to monitor their fields closely and take appropriate action when and where needed.
