Alert Details

A rather tranquil weekend with predominant northwest flow is expected to greatly limit any black cutworm migration prospects so little to no migration risk is in the forecast through next Monday morning. By next Monday and into the middle of next week, however, the weather pattern changes back to zonal or even southwesterly again, and southerly winds may result in isolated black cutworm migration events in the Plains and western corn-growing region by Monday night into Tuesday, and as far east as the southern Great Lakes region by Tuesday night into Wednesday. With more advanced planting progress this year, the primary focus with black cutworms is now focusing more across the northern corn-growing region and anywhere else that is late or in need of re-planted corn. Growers with newly-emerged corn should be scouting fields now and looking for signs of black cutworm larvae damage (holes in leaves or plants broken/cut off) until the crop advances in enough growth that cutworms are no longer of concern.
