Alert Details

With the primary storm track focused across the far southern corn-growing region and into the mid-south, the risk for corn earworm migration is temporarily out of the forecast with a dominant northwest flow across much of the Midwest. A quick-moving cold front late this weekend into early next week, however, may bring an isolated corn earworm moth flight risk initially from Kansas and Missouri northeast into eastern Nebraska, Iowa, southern Minnesota, southwest Wisconsin, and western Illinois Sunday night into Monday. The risk then shifts east with the front mainly into the southern Great Lakes region and eastern corn-growing region. With corn beginning to tassel in some areas, growers should be on the alert for potential new moth flights especially as cold fronts pass. The quick-moving nature of these weather systems, however, may limit the overall coverage for the time being.
