Alert Details

Corn earworm migration risks return to the forecast by late in the weekend and early next week as another weather system develops in the Plains states. High pressure is likely to move into the southeast United States, setting up a favorable corridor for southerly winds along with hot temperatures once again in the western and central corn-growing region. Low corn earworm migration risks are predicted from Kansas, Nebraska, and eastern South Dakota as far east as Lake Michigan and the I-57 corridor in Illinois, and also as far north as central Minnesota and Wisconsin. While many field crops are not at susceptible stages to damage, other plants/hosts such as vegetables, etc. may be closer or at a critical growth stage and usually in these early-season flights, the earworms find those fields and local high pressure can and does occur but problems are much more isolated, thus only Low risks despite a favorable weather pattern for migration.
