Alert Details

Isolated corn earworm moth flights may occur over the next 24 hours mainly along/east of the I-35 corridor in Missouri, central Iowa, and southeast Minnesota east into the I-69 corridor in south central Michigan southward into Indiana. A favorable corridor of southerly winds, originating in known corn earworm source regions in the mid-south, may result in a few moths flying north overnight tonight into tomorrow. Wind flow decreases thereafter so little to no risk is predicted mid-late week. This early season risk is mainly of concern to produce/fresh market and home gardens as field/sweet corn is not at susceptible stages to damage as of yet. Growers with crops at susceptible stages to damage should be monitoring traps and scouting plants for signs of corn earworm moths as a somewhat favorable pattern for at least isolated migration has occurred over the past few nights into portions of the corn-growing region.
