Corn rootworm.AMES, Iowa – Farmers, other agricultural professionals and interested parties who work with corn following a previous corn crop can attend a corn rootworm management webinar on March 26 at 10 a.m., hosted by Iowa State University Extension and Outreach, the University of Illinois Extension, and the University of Wisconsin Extension.

“The strong winds of last summer’s storms caused damage to many corn fields. Inspections of those fields revealed that many continuous corn fields had roots severely damaged by corn rootworms,” said Virgil Schmitt, field agronomist with ISU Extension and Outreach. “Those damaged roots have caused many growers, input suppliers and independent crop consultants to re-evaluate the corn rootworm management strategies in those fields.”

Webinar topics include a background and a research update on corn rootworms by Erin Hodgson, professor and extension specialist in entomology at Iowa State.

Other topics will include Bt resistance and corn rootworm management by Nick J. Seiter, assistant professor and field crop entomologist, University of Illinois; and diversifying corn rootworm management to delay Bt resistance by Bryan Jensen, entomologist with the Integrated Pest Management Program at the University of Wisconsin-Madison.
