Alert Details

A rather strong low pressure system developing in the Plains states with high pressure sliding into the southeastern United States is expected to set the stage for a potential early-season, first generation corn earworm moth flight over the next several days. While the threat to any crops at this point in the growing season is little to none, these early season flights can lead to greater pressure with additional generations later in the summer when crops are more likely to be at a susceptible stage to damage. Thus, it is important for growers to monitor traps even at this point early in the season. Low risks are predicted tonight into tomorrow morning from Kansas and Missouri northeast as far as eastern South Dakota, southern Minnesota, southwest Wisconsin, and western Illinois. Low risks then continue mainly across the southern Great Lakes region from I-35 east tomorrow night and Wednesday night, with risks then ceasing after a cold front clears much of the corn-growing region by the end of the week.
