Corn rootworm. A pest which causes over a billion dollars’ worth of damage annually across the United States and has crept up in numbers in Wisconsin. Emily Bick, UW-Madison Entomology Professor explains what we can expect this year from this pest and how farmers can take proactive measures to mitigate its impact on their crops.

Corn rootworm beetle pressure persists. Based on the high adult corn rootworm pressure observed last August, southern and western Wisconsin corn producers have been advised to closely review their rootworm management plans for 2023.

“Corn rootworm can cause extensive damage to corn crops,” says Bick. “Larvae feed on roots in late spring and early summer, causing stalks to tip over. Adults feed on leaves and silks in the late summer, inhibiting pollination. The number of adults in your field in the fall is an indicator of the larvae to be there in the spring.”
