Alert Details

The overall forecast has changed little from the past few days, with isolated corn earworm migration possibilities still expected generally from Kansas, Missouri, and southern Illinois northward into Iowa, the remainder of Illinois, and perhaps far southern Minnesota and Wisconsin the next couple nights. There is some concern that the northern limit of the migration chances may be further south especially given where the active storm track is at the present time (generally along/south of I-80), but still a few moths may make it further north into the I-90 corridor. As a cold front moves east, the migration risk also shifts east into lower Michigan, Indiana, Kentucky, and Ohio by Sunday night into Monday. While there is little to no threat to field corn especially at this growth stage given late planting, vegetable and fresh market growers should check traps and monitor their gardens/fields as some new moths may appear in the coming days. Little to no migration risk is anticipated once this front clears the corn-growing region by Monday or Tuesday next week.
