Alert Details

A weekend of northwest flow will limit corn earworm migration prospects, but by early to mid next week the next cold front is expected to move southeast and should provide a few days of southerly wind flow to its east as high pressure moves into the eastern/southeast United States. Low migration risks are predicted mainly west of the US 51 corridor or from Wisconsin and Illinois westward on Monday night with the risk shifting east across the southern Great Lakes and central/eastern corn-growing region primarily east of a line from near Springfield, Missouri to Wausau, Wisconsin but mainly west of I-75 in southeast lower Michigan and western Ohio on Tuesday night into Wednesday. Growers with crops at susceptible stages to damage should monitor traps and scout fields for signs of corn earworm. Flights thus far this summer into the corn-growing region have mainly been isolated but a few areas of higher moth captures have been reported.
