Alert Details

High corn rootworm risks remain in place for this week especially in fields along and north of I-90. Continued adult beetle emergence and field activity will be possible but the threat is largely over for many corn fields all across the corn-growing region for this growing season. Growers should continue to scout for corn rootworm and take note of beetle populations as high beetle populations may signal a need for a change to 2015 growing season planting intentions. Fields from the eastern Dakotas into Minnesota, far northern Iowa, Wisconsin, lower Michigan, and southwest Ontario, Canada are included in the risk area this week.
