Alert Details

Low pressure and an attendant cold front are predicted to continue to develop across the Plains and upper Midwest throughout this week. By late week, the cold front is predicted to pass through the entire corn-growing region while low pressure moves northeast and deepens across the upper Midwest and eventually into Canada. South to southwest winds are predicted to become more widespread in between the cold front and high pressure which should move further east into the eastern United States by mid-week. Low corn earworm migration risks are predicted initially across southern and central Minnesota as well as far western/northwestern Wisconsin tomorrow night into Wednesday morning and across Wisconsin and eventually lower Michigan and southwest Ontario, Canada by late week. There are still some processing fields at risk of seeing corn earworm damage across the risk area, so growers should continue to monitor moth activity and treat, as needed, in the coming week.
