Alert Details

Corn rootworm hatches will remain possible across especially far northern corn-growing region fields from North Dakota into northwest Minnesota and eastward into Minnesota, northern Wisconsin, portions of central lower Michigan, and into Ontario, Canada. Elsewhere, beetle presence will eventually become the primary concern and where fresh silks are present, growers are encouraged to count beetles and take note if counts meet or exceed threshold values for this insect. Virtually the whole of the corn-growing region is at risk of seeing some corn rootworm issues in one form or another from Kansas north into North Dakota and as far east as Ohio, Michigan, and into southern/southeastern Canada, as well.
