Alert Details

The weather pattern is expected to become more favorable for at least isolated corn earworm moth flights especially in the western and central corn-growing region starting Friday night and continuing into next week. South to southwest winds will increase from source regions in Texas later Friday initially across the Plains states as high pressure in the upper Mississippi River valley moves into the eastern Midwest. Low risks are predicted across Kansas and Nebraska for Friday night into Saturday morning, and then risks spread north and east into far southern South Dakota, southwest Minnesota, western Iowa, and far western Missouri by Saturday night into Sunday. The risk area continues to spread east into the Mississippi River valley and eventually to the western shores of Lake Michigan southward into eastern Illinois by early next week. While crops in much of this region have either just been planted or are in very initial growth stages, growers should still monitor potential host plants nearby for signs of first generation moths.
