Corn Rootworm
Corn rootworm risks continue across much of the corn-growing region, with the risk now shifting away from hatching to increasing beetle populations given a higher percentage of the crop now entering into silking stages and beyond. Some remaining hatches may still be possible in the far north region especially along I-94 in North Dakota and Minnesota, but further south increasing beetle populations will be the predominant issue going forward. Growers should scout fields and take note of populations, and also take note where any lodging caused by rootworms may be occurring and note these locations for the future. High rootworm risks continue across intensive corn acreage from Kansas into Nebraska, the eastern Dakotas, much of Minnesota, Iowa, northern Missouri, central and northern Illinois, Wisconsin, central and northern Indiana and Ohio, lower Michigan, and into southern Ontario, Canada. Moderate risks for scattered issues remain in place across eastern Colorado and fringe acreage areas further east.
