Alert Details

Black cutworm migration risks will continue for the next 24 hours especially over the southern Great Lakes and eastern corn-growing region as a cold front makes its way to the east. Southerly wind flow east of the front may lead to some isolated moth flights from mid-south and lower Mississippi River valley source regions into eastern Missouri, Illinois, and far southeast Wisconsin and points eastward. Little to no risk is predicted for the rest of the week, but Low risks have been introduced to the extended forecast as another weather system develops in the Plains and results in the potential for yet another opportunity for some moth flights by Saturday and into early next week. Initial risks with the weekend system are mainly west of Lake Michigan. Growers are encouraged to continue scouting efforts and also monitor any peak moth captures in April and early May as some new larvae are likely appearing in newly emerged corn fields especially in the central and eastern portion of the corn-growing region.
