Alert Details

A cold front will work its way southeast over the next 24-48 hours and will usher in a return to northwest flow across especially the central and eastern corn-growing region. South of the front, however, south to southwest winds are expected to continue and may pose an isolated corn earworm migration risk overnight tonight into midday tomorrow. The risk area lies generally along and south of I-80. Some of these areas already have corn earworm moths present due to being an overwintering region and/or from earlier flights this growing season so the risk level is kept in the Low category. No further risks are in place through early next week, but we encourage growers to continue to scout fields and monitor traps especially given the critical growth stage of many crops at this time.
