Alert Details

A cold front is expected to make progress southeast through at least a portion of the corn-growing region by the middle to end of this week. Southerly wind flow in advance of this front, however, is not expected to be very strong and with mid-south and southern states source regions still favorable hosts than further north, any risks higher than a Low risk in the main corn-growing region are not warranted at this time. Low migration risks are predicted mainly west of the Mississippi River tomorrow night into Wednesday morning ahead of this front, with the risk then focusing mainly east of a Dodge City, Kansas to Duluth, Minnesota line and west of Lake Michigan by Wednesday night into Thursday. The front is expected to push further southeast, but winds should lessen even more as the front weakens so no additional risks are predicted after midday Thursday. Fresh market, processing, and garden growers with vegetables and other hosts at susceptible stages to damage from corn earworm, including sweet corn growers, should monitor traps and scout fields as some localized flights could still occur in some areas.
