Low corn earworm migration risks are predicted as early as tomorrow night mainly west of Lake Michigan and the I-57 corridor in eastern Illinois. A cold front is expected to push southeast into the northern and western corn-growing region later today and into tomorrow, with an increasing south to southwest wind regime east of the front. The pressure gradient overall is not expected to be overly strong, thus only Low risks are in place at this time. Low risks continue into the weekend mainly across the southern Great Lakes and eastern corn-growing region ahead of this front. Growers with crops still at a susceptible stage to corn earworm damage, including processors and fresh market growers, should continue trapping and scouting efforts until either the threat has passed or harvest is complete.
