Alert Details

With a persistent pattern of south to southwest winds expected across a large portion of the corn-growing region in the next five days, corn earworm migration risks are on the increase as well. Moderate risks are in place for scattered moth flights tomorrow night into Sunday morning across portions of Kansas, Nebraska, South Dakota, Minnesota, Wisconsin, Iowa, and Missouri. Moderate risks are also predicted for Monday night into Tuesday morning primarily across Kansas, Nebraska, southeast South Dakota, southern Minnesota, Iowa, and Missouri as enhanced southerly winds in addition to precipitation areas potentially serving as drop zones are expected. Low risks cover much of the corn-growing region for the next five days. Growers across the entire Midwest are urged to monitor for signs of new migrant moths and fresh-market growers are especially cautioned to watch for increased moth counts on their crops.
