Alert Details

Low corn earworm migration risks are predicted tonight into tomorrow from southeast Nebraska and northern Missouri northward into Iowa, Minnesota, western Wisconsin, and western Illinois as a fairly narrow corridor of southerly winds sets up east of a cold front. A few isolated moth flights will be possible in the Low risk area before the cold front sweeps through by the weekend. Little to no migration risk is predicted into early next week after tomorrow, but growers with crops still at susceptible stages to corn earworm damage, especially processors and fresh market growers in the northern growing areas, should continue scouting and trapping efforts until harvest.
