Alert Details

A cold front is still expected to move southeast through much of the corn-growing region over the next 2-3 days. Southeast of this front, winds are expected to be from the south or southwest and may lead to some isolated corn earworm moth flights overnight tonight into tomorrow from Kansas and Missouri northeast as far as southern Minnesota, Wisconsin, and also potentially into southwest lower Michigan and Indiana. Low risks continue in the forecast tomorrow night into Sunday mainly southeast of a line from Dodge City, Kansas to north of Milwaukee, Wisconsin as the front moves southeast. Given crop conditions and also harvest progress in the southern source regions (Texas, most notably), there is a potential for a few more intense flights in some areas as source region crops are either not in the greatest shape in many areas or have been harvested now so some moths are looking for new food sources and may be more inclined to fly north. Growers should monitor traps and scout fields diligently in the coming weeks as moths may appear a little sooner this year compared to the past given these factors.
