Alert Details

A slow-moving cold front is expected to move through the corn-growing region this weekend into early-mid next week. East of the front, rather warm to even hot conditions (for the time of the year) are expected as southerly winds increase into the region. These winds may also produce some isolated corn earworm moth flights, especially over shorter distances from the southern corn-growing region further to the north. Low risks are predicted from Saturday night into Sunday and then again into early next week across portions of northern Missouri, eastern Iowa, Wisconsin, central and northern Illinois, northern Indiana, northwest Ohio, and central/southern lower Michigan. Processing and fresh market growers are encouraged to continue to monitor traps and scout fields as these are the fields that are likely left to serve as suitable hosts for any migrating corn earworms at this time.
