Alert Details

Until the very end of the five day period, no risk of corn earworm migration is predicted. Persistent northwest to southeast flow is predicted to hold across much of the central United States through this weekend, and not until next week should southerly flow that may potentially result in at least isolated corn earworm migration return to the corn-growing region. By early next week, a low pressure system should begin organizing in the central Plains. High pressure is expected to advance southeast into the southeastern United States which may result in southerly winds blowing from the mid-south into primarily the southern Midwest. Low migration risks are predicted for a good portion of Kansas east into Missouri next Monday night and Tuesday morning. Corn in the risk area is not at a stage where damage could occur, but growers should be aware that some isolated moth flights may be possible next week especially in the southern Midwest.
