Alert Details

High corn rootworm risks remain in the forecast across much of the whole of the corn-growing region in the next week. Over threshold beetle populations have been reported in scattered areas of the corn-growing region in the past week or so, with some fields warranting treatment and/or the need for potential crop rotation changes next growing season. If corn rootworms have been a problem in the past few years locally, growers are advised to scout fields and assess beetle populations. Risks continue across Kansas, Nebraska, North and South Dakota, Minnesota, Iowa, northern Missouri, Illinois, Wisconsin, lower Michigan, Indiana, Ohio, and into southern Ontario, Canada, as well.
