Alert Details

Despite daily corn earworm migration risks, the overall threat is rather low due to a predicted lack of stronger southerly winds and widespread precipitation that may serve as a potential drop zone region. Low risks are primarily focused across the southwestern portion of the corn-growing region for the next four nights (mainly from Kansas into Nebraska, Iowa, Missouri, and portions of Illinois) but do expand north into the upper Midwest (South Dakota, Minnesota, and Wisconsin) by the end of the five day period. With field corn tasseling/silking rates increasing across many areas and sweet corn fields already at critical stages, growers should continue to monitor their fields for isolated corn earworm moth flights especially across the southwestern corn-growing region in the next five days.
