Alert Details

Southerly wind flow is expected to return initially to the Plains states and western corn-growing region by mid-week in response to high pressure moving east from the northern corn-growing region east into the Great Lakes and eastern United States, but also as low pressure develops in southern Canada. The primary concern at this point in the growing season is with processors and fresh market crop growers in the northern corn-growing region where corn earworms may still be a continuing threat. Low migration risks are predicted late Wednesday into Thursday mainly west of the Mississippi River, with the risk eventually spreading as far east as southwest lower Michigan and into northern Indiana by late week and into the start of next weekend. Growers with crops still at critical stages of growth where corn earworms could cause damage should continue scouting and trapping efforts until harvest.
