Alert Details

Black cutworm migration risks are in the Low category tonight into tomorrow morning as a cold front moves east across the central and eventually eastern corn-growing region. Risks mainly focus along/east of the I-55 corridor from southeast Missouri into Illinois where south to southwest winds are expected to be more widespread. As one system departs, another develops in the Plains states and this one may bring a more widespread black cutworm migration risk to the corn-growing region. Low risks are predicted generally along/west of the Mississippi River tomorrow night into Friday, but then expand east and risk upgrades in the Moderate category are in store for Friday night into Saturday from Nebraska and eastern South Dakota as far east as southwest lower Michigan and Indiana. Moderate risks continue in the forecast Saturday night into Sunday mainly across the southern Great Lakes region and central/eastern corn-growing region east of I-35 as a cold front begins to push southeast. Growers should be advised that while there is no threat to crops right now, these flights may result in generations especially in May that may impact newly-planted corn so flights should be documented at this time.
