Alert Details

With northwest flow returning to much of the corn-growing region, no risk of black cutworm migration is predicted until early next week when the next weather system begins to develop in the Plains states. By next Monday into Tuesday, high pressure is likely to move into the eastern or southeastern United States as low pressure develops over the southern Plains. Low pressure should emerge into Kansas by Monday, and southerly winds are likely to return to at least the southern and central portion of the corn-growing region by Monday. Low black cutworm risks are predicted as far north as southeast South Dakota, southern Minnesota and Wisconsin, and also into southern lower Michigan by next Monday night and Tuesday morning with the risk extending from eastern Kansas and Nebraska into western Ohio by that time. In the meantime, growers especially across the eastern corn-growing region should monitor for signs of new additional flights, especially in areas where corn planting has been delayed by wet weather in the past several weeks.
