Alert Details

High pressure is expected to keep most of the corn-growing region a little cooler over the weekend, but heat along with an increase in southerly winds is likely initially across the Plains states this weekend before spreading east into the heart of the area by early next week. Even though the majority of host plants and field crops are not at a susceptible stage to corn earworm damage at this point in the growing season, a favorable pattern for migration is expected late in the weekend into early next week before a cool front passes by Tuesday/Wednesday. Given these factors, a Low risk is warranted as some moth flights are still possible and any plants at susceptible stages to damage (vegetables, etc.) may see some localized pressure. Low risks are predicted from Kansas, Nebraska, and South Dakota east as far as Lake Michigan and into Illinois and as far north as Minnesota and Wisconsin from late Sunday into Tuesday.
