Alert Details

A cold front is expected to move southeast through much, if not all, of the corn-growing region by the end of the week. To the southeast of the front, primarily modest south to southwest winds may allow for some isolated corn earworm moth migrations to occur especially tomorrow night into Thursday from Texas northeast into the heart of the corn-growing region in Iowa, Illinois, southern Wisconsin, and adjacent states. As the cold front moves southeast, the risk area also shifts southeast but winds weaken rather considerably, so the migration risk is not all that great but still not zero for areas mainly east of the I-55 and I-57 corridors in far southeast Missouri and central/eastern Illinois. The main concern at this point in the growing season is with fresh market and garden crops, and these growers should monitor traps and scout their produce and plants especially if in or near a critical growth stage.
