A quick-moving but rather potent area of low pressure and associated cold front is predicted to advance from west to east across the corn-growing region late this week and into the weekend. South to southwest winds are expected to be prevalent to the east of the cold front and may pose a Low corn earworm migration risk especially for processing and fresh market fields still at susceptible stages of growth in the upper Midwest. Low risks are in place from eastern South Dakota into far northern Iowa, central and southern Minnesota, and Wisconsin tomorrow night into Saturday morning, and across lower Michigan and southern Ontario, Canada Saturday night into Sunday morning as the cold front moves east. Precipitation along and east of the front may result in some insect drop-out along and east of the front during these time periods. Growers with crops still at susceptible stages to damage are encouraged to monitor traps and field activity in the next week for signs of new moths.
