Alert Details

Corn rootworm beetle count risks continue in the High category for the next week across a large portion of the corn-growing region from eastern Colorado into Kansas, Nebraska, the Dakotas, Minnesota, Missouri, Iowa, Illinois, Wisconsin, Indiana, Ohio, lower Michigan, and into southern Ontario, Canada. Corn rootworms have and probably still are causing problems in the corn crop this year on a scattered basis, and growers should pay attention to where beetles are present even if counts are not at or above treatment threshold levels as that may affect next year’s planting intentions. The overall risk is diminishing on the south end of the corn-growing region as crop dries down and nears maturity, but continued scouting is encouraged further north for another few weeks.
