Alert Details

A very persistent weather pattern featuring primarily light southerly winds, near to above average temperatures, and little precipitation chance is expected to envelop much of the corn-growing region in the next five days. For corn earworm migration purposes, the result will be continued nightly chances of isolated moth flights throughout much of the corn-growing region. The lack of stronger southerly winds and precipitation, however, does not justify higher risks at this time. Initially, the Low risk region focuses mainly across the Plains and western Midwest, but the risk does spread east to include fields as far east as Michigan, Indiana, and Kentucky by Saturday night into Sunday. Fresh market and commercial growers all across the corn-growing region should monitor their crops for signs of corn earworm moths in the next five days as many fields are now or will be at susceptible stages to damage.
