Alert Details

Western bean cutworms will continue to pose a threat to crops, mainly on a scattered basis, across lower Michigan east into Ontario and southwest Quebec, Canada as well as potentially into upstate New York and Vermont in the next week. High risks remain in place across southwest Ontario, Canada where the greatest pressure and earliest crop stages are located. Moderate risks for more scattered problems remain in the forecast across central and eastern lower Michigan with Low risks in place from lower Michigan east into parts of New England, as well. All risks have been removed west and south of the Great Lakes as the majority of crops are past critical stages of growth and also where peak flight has largely ended for this growing season. Growers in the Great Lakes region, however, are advised to continue to monitor traps and scout fields as damage will still be possible to corn and other vegetables/crops in the next week or so until the annual flight subsides.
