Corn rootworm hatch is predicted to continue across a good chunk of the corn-growing region in the next five days. Fields from Colorado into Kansas, Nebraska, southeast South Dakota, southern Minnesota, Iowa, northern Missouri, Illinois, southern Wisconsin, southwest Michigan, Indiana, and Ohio are all at risk of seeing hatch and small larvae potentially causing problems in corn fields. Growers are urged to monitor their fields closely for signs of small larvae and take appropriate action when and where needed.
