Alert Details

Western bean cutworms are expected to continue to cause scattered problem areas but especially focused closer to the Great Lakes region and further northeast into Canada as time goes on. High risks remain from northeast Nebraska into far southeast South Dakota, northern Iowa, southern Minnesota, and central Wisconsin to the west of Lake Michigan. Further east, High risks remain from central and northern Michigan into southern Ontario, Canada where pressure appears to be the greatest at this time. Moderate risks remain in place from Nebraska into South Dakota and points further northeast into Iowa, Minnesota, Wisconsin, northern Illinois, lower Michigan, northern Indiana, northern Ohio, northwest Pennsylvania, northwest New York, and southern Ontario into southwest Quebec, Canada. Growers in the High and Moderate risk areas should continue to monitor their crops for western bean cutworm activity and take appropriate action if needed.
