Corn Earworm
A low pressure system and attendant cold front are predicted to develop in the Plains states over the next few days and eventually move northeast into the upper Midwest and Canada by early next week. A Low corn earworm migration risk will exist along/east of the front in a corridor of south to southwest winds and at least scattered areas of precipitation. The risk is initially focused on the I-35 corridor from near Kansas City northeast into Minnesota Sunday night into Monday, and then across the southern Great Lakes and upper Mississippi River valley Monday night into Tuesday. While these early flights generally do not cause any problems to any crops, they can result in additional generations later this summer that could result in crop damage. As a result, growers should still monitor for signs of new corn earworms as we move into next week.
