A strong cold front is likely to push through the corn-growing region over the next several days. To the east of the front, south to southwest winds are expected to increase as is precipitation, so the potential for scattered corn earworm moth flights will exist across a large portion of the upper Midwest and Great Lakes region. Growers with crops at susceptible stages, especially processors and fresh market growers in the upper Midwest through the Great Lakes region, should monitor traps and scout fields in addition to being prepared to treat where new flights are anticipated. Moderate risks are predicted tonight into tomorrow morning across Nebraska, Iowa, far southeast South Dakota, southern Minnesota, and western Wisconsin. The risk shifts east and southeast with the front tomorrow night into Saturday morning, and includes eastern Iowa, southeast Wisconsin, northern and central Illinois, northern Indiana, far northeast Missouri, and extreme southwest lower Michigan. The Moderate risk area then focuses across central and northern Indiana and Ohio, lower Michigan, southern Ontario, Canada, western Pennsylvania, and western New York state by Saturday night into Sunday. No risk is predicted thereafter until likely sometime early-mid next week.
