Alert Details

The strong low pressure system that developed last week in the Plains is finally pushing a cold front through the central and eastern corn-growing region. This front will limit any potential black cutworm migration events for the corn-growing region, thus little to no migration risk is predicted for much of this week as northwest flow returns in its wake. By late week and into next weekend, a new low pressure system and associated southerly winds are likely to return to a portion of the corn-growing region. Low migration risks are in the forecast from Kansas and Missouri as far northeast as Wisconsin and east into portions of Indiana. Details regarding this system are still being worked out but stay tuned for forecast updates this week. Regardless of any risk, growers should continue to monitor traps and document when flights have occurred as new generations from recent flights may affect newly-emerged corn next month in many areas given the number of potential moth flights that have occurred in the past several weeks especially in central and eastern portions of the corn-growing region.
