Is corn rootworm a big problem?
• Corn rootworm used to be a significant insect pest when growing continuous corn was a common practice. Rootworm eggs are able to overwinter in fields and re-infest when corn is returned to the same field. Crop rotation is an effective control measure – and sound agronomic practice – to reduce corn rootworm. However, as the economics of growing corn continue to improve, the temptation to grow consecutive corn crops in the same field also rises – increasing the threat of corn rootworm infestation.
