Alert Details

A strong cold front will continue to push east through the corn-growing region today. The front serves as a dividing line between south to southwest winds to the east of the front and increasing west to northwest winds, and much cooler air, to the west. Any corn earworm migration will occur to the east of the front across the eastern Great Lakes region and eastern Midwest, or roughly from I-69 east from far northeast Indiana into southeast lower Michigan, northern Ohio, northwest Pennsylvania, southern Ontario, Canada, and western New York. No additional corn earworm migration possibilities are in the forecast through early next week, but fresh market and processing growers in the upper Midwest should continue to monitor fields still at susceptible stages to damage as moth flights in recent weeks have resulted in high moth captures and increased larval activity in fields.
