Alert Details

The first corn earworm migration risks for this growing season enter the forecast next Tuesday night into Wednesday as a seasonably strong low pressure system is predicted to develop in the Plains states. As high pressure moves into the southeast United States, a favorable corridor for south to southwest winds is likely to develop from the mid-south region northward into especially the central portion of the corn-growing region. Low migration risks are in the forecast from eastern Kansas and far eastern Nebraska and Missouri north into Iowa, Minnesota, Wisconsin, Illinois, Indiana, southwest lower Michigan, and extreme western Ohio. While there is no threat to any crops at this point in the growing season, growers should be aware that early-season moth flights, especially those that are more intense, can lead to greater problems later in the growing season once the second generation develops.
