Low corn earworm migration risks remain in the forecast for the next three nights as southerly wind flow ahead of a cold front is likely to persist. The greatest risk for any potential migration events tonight through tomorrow is mainly along and south of I-90 west of the Mississippi River and then further east, northeast across Wisconsin into lower Michigan and adjacent portions of the southern Great Lakes region. The primary focus tomorrow night into Sunday is mainly along and south of I-90 west of the Mississippi River, and then east through central/southern Wisconsin and into southern lower Michigan. As the cold front begins to move southeast by late in the weekend and early next week, any migration chances by Sunday night into Monday should lie mainly east of the I-35 corridor from central Iowa northeast into southeast Minnesota and Wisconsin and points southeast. The front moves southeast of the corn-growing region by Monday into Monday night, so no further risks are needed thereafter. Growers, however, are encouraged to monitor traps and scout susceptible fields at this time, especially fresh market and vegetables as these are the most likely fields to see potential problems.
