Alert Details

Corn rootworms are predicted to continue hatching in fields from northeast Colorado through Kansas, Nebraska, Iowa, Missouri, Illinois, Indiana, and Ohio in the next five days. Additionally, as air temperatures rise (and subsequently, soil temperatures increase) especially by this weekend and early next week, some fields in South Dakota, Minnesota, and Wisconsin may also see corn rootworm larvae show up in fields. Growers are urged to monitor their fields closely for signs of small larvae and take appropriate action when needed.
