Alert Details

As a cold front slowly pushes east through the corn-growing region, corn earworm migration risks will also focus more to the east across the eastern Midwest and southern Great Lakes region. Moderate corn earworm migration risks are predicted tonight into Saturday morning primarily east of I-57 in southeast Missouri and eastern Illinois into Indiana, southern Michigan, southwest Ontario, western and central Ohio, and Kentucky. Growers in these areas should be on the lookout for scattered moth flights and moth presence especially on host plants. A Low risk remains mainly across Indiana, Ohio, lower Michigan, Kentucky, and southwest Ontario Saturday night into Sunday morning as the front continues to move east but where southwest winds may still pose an isolated moth flight risk. Looking ahead to next week, the next weather system in a continued active pattern should be advancing east into the Plains, and Low migration risks are in place across Kansas and Nebraska by Monday night into Tuesday with the risk spreading north and east by Tuesday night into Wednesday.
