Alert Details

The next in what appears to be a potential series of weather systems begins moving into the western corn-growing region by the weekend. As high pressure moves to the east, south to southwest winds are expected to return to the Plains states initially by Saturday and then spread east. Low black cutworm migration risks are predicted mainly along and south of I-90 by Saturday into Sunday morning, with the Low risk continuing in the forecast until at least Tuesday when the cold front moves through. A possible upgrade to a Moderate risk may be warranted for early next week but lower confidence in forecast details this far out precludes the risk at this time. Growers should continue monitoring traps and checking heat unit accumulations especially if corn is beginning to emerge as flights from earlier this spring may now be producing larvae.
