Alert Details

Black cutworm risks return to the forecast beginning next Monday night as low pressure develops in the Plains states and high pressure moves into the southeastern United States. In between the two pressure centers, we expect south to southwest flow to develop. At this point in the growing season, we expect the greatest pressure from any new black cutworm moth flights to be focused across the northern portion of the corn-growing region. Low risks are predicted mainly along and north of I-80 from eastern Nebraska and South Dakota east into Wisconsin and Illinois Monday night into Tuesday morning, and then primarily from Minnesota and Iowa east into the southern Great Lakes region Tuesday night into Wednesday morning. Growers all across the corn-growing region, however, should monitor and scout fields closely as larvae may now be affecting some emerged corn given the high number of moths captured in portions of the corn-growing region in the last month and a half.
