Alert Details

A continued progressive weather pattern is predicted to remain in place across the corn-growing region in the next week. As a result, corn earworm migration risks will continue on a periodic basis, but the overall threat will only be in the Low category given the limited number of fields remaining with a potential risk and the late point in the growing season. Processors and fresh market growers should continue to monitor traps and take appropriate action where needed. Low risks are in place from northern Iowa into Minnesota, Wisconsin, and northern Illinois tomorrow night into Friday morning as the next cold front moves southeast. This risk area shifts into the southern Great Lakes region from eastern Illinois into southern lower Michigan, northern Indiana, northern Ohio, and southwest Ontario, Canada Friday night into Saturday morning. An additional Low risk is back in the forecast already by Sunday night into Monday especially across northern Iowa into Minnesota as the next cold front begins charging southeast through the corn-growing region.
