Growers from northeast Colorado into northern Kansas, Nebraska, South and North Dakota, Minnesota, Iowa, northern Missouri, central and northern Illinois, Wisconsin, Michigan, Indiana, Ohio, and Ontario, Canada all need to be on the lookout for corn rootworm beetles and take appropriate action if counts reach or exceed threshold values.
