Alert Details

A cold front is predicted to pass through the corn-growing region over the course of the next few days. South to southwest winds in advance of the front may provide an isolated corn earworm migration risk, but the source region is expected to be in a less active corn earworm region in Texas and Oklahoma. As a result, only Low migration risks are predicted from Kansas into Nebraska and South Dakota as well as southern Minnesota, Iowa, and Missouri tonight into tomorrow morning and from Kansas and Missouri northeast into Iowa, Illinois, southern Wisconsin, Indiana, southern lower Michigan, western Ohio, and far northern Kentucky tomorrow night into Saturday morning. The cold front moves southeast through much of the corn-growing region on Saturday and Saturday night so no further risks are being predicted as northwest winds and high pressure once again lock in across the heart of the corn-growing region next week. Growers throughout the corn-growing region are advised that despite a higher migration risk, there are still corn earworm larvae present in many areas and with crops at susceptible stages to damage, continued scouting and management practices, if needed, are still encouraged.
