Alert Details

Corn earworm migration risks return to the forecast beginning tomorrow night into Wednesday morning mainly across the southwest portion of the corn-growing region as the next low pressure system and cold front develop in the Plains states. South to southwest winds are likely east of the front and they are expected to be rather gusty, so Low migration risks are predicted tomorrow night into Wednesday morning mainly along/south of US 12 in South Dakota and Minnesota southeast to near Milwaukee, Wisconsin and primarily west of the I-55 corridor in Illinois. Low risks continue in the forecast mainly east of I-35 Wednesday night into Thursday morning as the front slowly moves southeast. The front looks to stall out for a day or so late this week, so Low migration risks remain in the forecast mainly east of I-35 and along/south of I-80 by late week with the risk focusing mainly east of I-55 in central Illinois by Friday night into Saturday morning as the front finally pushes to the east. Fresh market and vegetable growers should pay close attention to traps and scout their fields/gardens as sweet corn and other vegetables reach critical growth stages as new moth flights may result in damage in the next few weeks.
