Alert Details

The annual western bean cutworm peak flight has subsided in most fields in the corn-growing region for this growing season. There are still some higher moth counts especially in portions of the eastern Great Lakes region but otherwise risks are quickly being reduced especially as crops move past critical growth stages next week with the expected heat and a continued decline in trap counts and moth activity in fields. High risks remain in northeast lower Michigan for another day with High risks remaining in southern Ontario, Canada where counts appear to be consistently the highest. Moderate risks remain through tomorrow morning in the central sands region of Wisconsin but even there, risks are being quickly removed as moth presence is dwindling. Moderate risks are maintained through the middle of next week from northeast lower Michigan into southern Ontario and southwest Quebec, Canada. Growers especially in the eastern Great Lakes region should monitor their fields for western bean cutworms and take appropriate action if fields are still at susceptible stages to damage.
