Corn earworm migration risks are predicted to continue for the next five days as an active weather pattern remains across much of the corn-growing region. Migration risks are focused primarily at sweet corn growers during this time period as commercial field corn crops are not at a stage where CEW damage would result. Low migration risks are in place tonight into tomorrow morning across the Great Lakes region and eastern Midwest as the first weather system and associated cold front moves through this region. South to southwest winds may result in some isolated moth flights into fields mainly east of I-55 and Lake Michigan. After tomorrow morning, focus then shifts back west across the Plains and western corn-growing region as the next weather system begins to develop. Low risks are in place across Nebraska, western Iowa, Kansas, and far western Missouri as southerly winds increase. Moderate migration risks return by Saturday night/Sunday morning and again Sunday night/Monday morning initially across the Plains but spreading east into the corn-growing region mainly west of Lake Michigan by Monday morning. Low risks encompass virtually all of the corn-growing region by the extended period so fresh market growers with early planted sweet corn that may be tasseling now should especially monitor their fields for new migrants in the next week.
