Alert Details

A persistent stretch of favorable weather conditions for corn earworm migration is predicted through the next five days and likely beyond. South to southwest winds originating from northern Texas, Oklahoma, Kansas, southwest Missouri, and Arkansas are expected to blow north into much of the corn-growing region starting tonight and continuing into next week. Moderate risks, as a result, are in place every night through the next five days. Moderate risks will initially be focused over the western corn-growing region but will spread east into the Great Lakes and portions of the eastern Midwest by early next week. Fields in Kansas, Nebraska, South Dakota, North Dakota, Minnesota, Iowa, Missouri, Illinois, Wisconsin, Michigan, Ohio, Indiana, and Kentucky are all under a Moderate risk at some point in the next five days. Growers with late planted crops that may still have fresh silks or vegetables that are at susceptible stages to damage should monitor their crops very closely in the next week for increased corn earworm moth presence.
