Alert Details

Moderate black cutworm migration risks are in the forecast the next two nights as gusty southerly winds to the east of a cold front in the Plains states may result in scattered moth flights into portions of the central and northern corn-growing region. Moderate risks are in place tonight into tomorrow morning across portions of Nebraska, South Dakota, Minnesota, Iowa, and Wisconsin with Moderate risks also continuing in the forecast tomorrow night into Friday across Iowa, Minnesota, Wisconsin, and into northern Illinois. Low risks extend further east into the southern Great Lakes and eastern corn-growing region mainly the west of I-75 where southerly winds are expected to be weaker and any flights more isolated. Only Low risks remain in the forecast Friday night into Saturday as the front continues to push southeast but southerly winds to its east really diminish. Growers are encouraged to monitor traps and be prepared for potential new generations once crops emerge and enter into early vegetative growth stages later this month and potentially into June given average late planting progress ongoing this year.
