Corn Rootworm
Corn rootworm hatch risks extend across virtually all of the corn-growing region, with the greatest number of hatches expected in higher heat unit accumulating areas and also more intensive corn crop acreage regions from Kansas into eastern Nebraska, southeast South Dakota, southern Minnesota, Iowa, northern/central Missouri, much of Illinois, central and southern Wisconsin, Indiana, Ohio, and into southern lower Michigan. More scattered risks are expected from eastern Colorado into western Kansas, central/western Nebraska, central and southeast/eastern North Dakota, northwest into central Minnesota, and on east into northern Wisconsin, central lower Michigan, and also into southern Ontario, Canada. Growers across the corn-growing region are encouraged to dig up roots and even look for signs of lodging in the more advanced crops that may indicate rootworm presence. Corn rootworm beetles may become more of an issue in the most advanced/silking crops in the southern corn-growing region in the coming weeks, as well, and risks will be continued to account for this generational risk.
