Alert Details

The annual western bean cutworm peak flight has either subsided or will continue to subside across much of the corn-growing region over the course of the next week or so. High risks remain across portions of the Great Lakes region and into Canada where moth captures and field reports indicate the presence of western bean cutworms and also where potential damage may still occur. Fields from Wisconsin remain in the High risk for another day while fields in northern lower Michigan and southern Ontario, Canada remain in the High risk through the balance of the five day period. Moderate risks remain in place from west of Lake Michigan east into Michigan, northern Ohio, northwest Pennsylvania and New York, and southern Ontario and southwest Quebec, Canada. Growers that have late planted fields especially in the Great Lakes region and southeast Canada should continue to monitor their fields for signs of western bean cutworms and take appropriate action, if warranted.
