Alert Details

A strong cold front will move through the corn-growing region over the next 24-48 hours. East of the front, however, there will be continued gusty south to southwest winds and areas of showers/thunderstorms may provide a focal region for insect drop-out. Given these factors, Moderate black cutworm migration risks continue in the forecast tonight into tomorrow from central Missouri, far eastern Iowa, and southeast Wisconsin and points east into the I-75 corridor from lower Michigan into western Ohio and central Kentucky. The front looks to move through the eastern corn-growing region by tomorrow night, greatly limiting any further migration risks as winds switch to the west and northwest. Little additional migration risk is predicted for the rest of the week and into early next weekend. Growers should continue to monitor traps and also scout fields with emerging corn, looking for signs of black cutworm larvae and damage.
