Alert Details

A cold front will be pushing to the southeast through roughly the southeastern half of the corn-growing region over the next few days. Ahead of the front, clusters of showers and thunderstorms along with southwest winds are likely. The combination of these two features may lead to some isolated corn earworm moth flights northward from source regions in the mid-south region tonight into tomorrow and again tomorrow night into Saturday morning before the front clears the region. Low risks are in place tonight through midday Friday from eastern Kansas into Missouri, southeast Iowa, far southern Wisconsin, Illinois, Indiana, Ohio, southern lower Michigan, and also into southern Ontario, Canada. Low risks are focused mainly along and east of the I-57 corridor in far eastern Illinois tomorrow night into Saturday morning. No additional risks are currently predicted after midday Saturday, but fresh market and vegetable growers are urged to monitor traps closely and take any appropriate action should moth counts meet or exceed threshold values.
