Alert Details

A couple of cold fronts moving through some or all of the corn-growing region may pose isolated corn earworm migration risks in the next five days. The first cold front is predicted to pass through most of the corn-growing region between late Saturday and early Monday. South to southwest winds in advance of the front may pose an isolated migration risk initially for the Plains states Friday night into Saturday and across portions of Kansas, Nebraska, South Dakota, Minnesota, Iowa, Wisconsin, Missouri, Illinois, Indiana, and Michigan Saturday night into Sunday morning. Another Low risk is in the forecast at the end of the forecast period next Monday night into Tuesday across the Plains and western Midwest as the next cold front begins advancing into the western Plains and as southerly winds east of the front increase. At greatest risk at this point in the growing season are fresh-market and late planted processing crops. Growers with crops still at susceptible stages should continue to monitor their fields for signs of corn earworm and the potential for some new migrants through early next week.
