Alert Details

No risk of corn earworm migration is predicted until early next week when low pressure is predicted to develop across the Plains and deepen with time. As high pressure moves from the Great Lakes into the eastern United States, south to southwest winds will likely increase especially by Monday of next week especially across the central portion of the corn-growing region. At this time, the only real insect migration risk is focused in intentionally late-planted processing and fresh-market crops across the upper Midwest, so Low risks are in the forecast from northern Iowa and Illinois into Minnesota and Wisconsin next Monday night into Tuesday morning to cover the risk for some isolated moth flights into fields still at a susceptible stage to damage. Even though we are getting late in the growing season, growers with crops still at susceptible stages to damage should continue to monitor fields and traps, as needed, as we move into next week.
