Alert Details

Corn earworm migration risks are in the forecast on a daily basis all this week across at least a portion of the corn-growing region, but flights are predicted to be isolated and not affect crops at this point in the growing season. These flights, however, may result in additional generations later this summer so flight intensity should still be monitored despite no threat to crops at this time. Low risks are predicted tonight into tomorrow morning from eastern Kansas into Missouri and Illinois north into far eastern Nebraska, Iowa, Minnesota, and Wisconsin. The risk shifts along/south of I-80 tomorrow night into Wednesday morning. By late week into next weekend, the risk area begins to shift back north as low pressure develops in the Plains and a cold front moves east. Low risks extend as far north as Minnesota, Wisconsin, and Michigan by late Friday into Saturday morning.
