Alert Details

Low corn earworm migration risks are in the forecast beginning Sunday night and continuing into next week as an active weather pattern focuses across the corn-growing region. A battle zone between heat and humidity in southwest areas and cooler/drier air to the north will result in a warm front draped from west to east across the heart of the corn-growing region. South to southwest winds south of the front in combination with precipitation, some heavy, along the front may lead to some isolated moth flights near and south of the front. For now, Low risks are in the forecast from roughly I-90 and points south and as far east as I-69 in eastern Indiana. With crops now in or entering critical growth stages, it will be important to monitor traps and scout fields to determine if treatment is necessary based on local/in-field conditions.
