Alert Details

With the corn crop into or pushing to maturity in many areas and harvest commencing, the overall corn rootworm threat has decreases and is confined mainly to western and northern reaches of the corn-growing region where a higher percentage of fields are still proceeding through grain fill. Low risks are in the forecast for this week across northeast Colorado into Nebraska, the Dakotas, northern Iowa, Minnesota, Wisconsin, lower Michigan, and into southern Ontario, Canada but will be removed from the forecast later this week or by next weekend as the overall threat has passed and attention shifts from scouting to harvest.
