Alert Details

Corn rootworm hatch is predicted to continue in fields from northeast Colorado into Nebraska, Kansas, Iowa, Missouri, Illinois, Indiana, and Ohio in the next five days. With average to above average temperatures expected across much of the corn-growing region in the next week, additional fields further north will likely be added by early next week. Growers included in the risk area are urged to monitor their fields closely for signs of rootworm larvae and take appropriate action where needed.
