High corn rootworm hatch risks continue across virtually the entire corn-growing region from Colorado into Kansas, Nebraska, South Dakota, North Dakota, Minnesota, Iowa, Missouri, Wisconsin, Illinois, Michigan, Indiana, Ohio, and southwest Ontario, Canada. Additionally, corn rootworm emergence risks exist primarily in fields along and south of I-80 through the next five days. Growers all across the corn-growing region should monitor their fields closely for signs of corn rootworm and take appropriate action if and when needed.
