Increased corn earworm migration risks are in the forecast on an almost daily basis over the next weekend as a favorable migration pattern is predicted. A cold front is expected to push through at least the eastern two-thirds to three-quarters of the corn-growing region by Sunday into Monday, and along/southeast of this front is where the best migration probabilities will exist. Low risks are in the forecast tonight into tomorrow morning from mainly I-90 south and generally west of I-57, or from the central Plains east into Illinois, and as far north as southern Minnesota and Wisconsin. Moderate risks are the in the forecast for the next three nights and early morning hours. Friday night into Saturday morning finds the risk from northern Kansas and Missouri northward into eastern South Dakota, Minnesota, and far southwestern Wisconsin. Saturday night into Sunday morning the risk is located mainly east of a line from near Hays, Kansas to Minneapolis, Minnesota to extreme southwest lower Michigan and northwest Indiana. As the cold front pushes southeast into the Great Lakes region and eastern corn-growing region by Sunday night into Monday morning, Moderate risks are predicted generally along and east of I-57 in far eastern Illinois into Indiana, Ohio, lower Michigan, and also into southern Ontario, Canada. Growers are encouraged to monitor traps during the next week to monitor for new moth flights and take appropriate action when and where needed.
