Alert Details

Black cutworm migration risks are in the forecast tonight into tomorrow from Kansas and Missouri as far north as South Dakota, Minnesota, and Wisconsin and as far east as Illinois as south to southwest winds blow from source regions especially in Texas and Oklahoma northeast. Precipitation may serve as isolated to scattered drop zones in this area. The overall risk level is being kept in the Low category, however, as winds are not expected to be overly strong and the source region not optimal. Little to no additional migration risk is in the forecast this week despite a somewhat active weather pattern across the corn-growing region, again mainly due to rather weak winds but also some uncertainty in the forecast confidence with the track/strength of an upper level low pressure system by late week. Growers with newly-emerged corn are encouraged to scout fields and look for signs of black cutworms especially given the numerous flights that occurred earlier this spring in many areas.
