Alert Details

The overall weather pattern across the corn-growing region is expected to transition to more of a southwesterly flow by later this week and into the weekend. The result will be an increase in at least isolated black cutworm moth probabilities for a large portion of the area at some point during this time. Low risks are initially focused west of I-35 in the Plains and Missouri, Iowa, and Minnesota by as early as tomorrow night into Thursday, but then expand east to Lake Michigan and the I-57 corridor in eastern Illinois by Thursday night into Friday. Over the weekend, there is some disagreement in where frontal boundaries may lay out, but the general theme is the same with a broad-brushed approach to potential isolated moth flights anywhere generally along/west of the I-75 corridor in southeast lower Michigan and western Ohio. Growers should continue to scout fields especially where corn is newly emerging as larvae from earlier flights last month may now be present.
