Farmers, ag professionals and other interested parties who work with corn after corn will want to attend a corn rootworm management webinar 10 a.m. March 26. It is hosted by Extensions from Iowa State University, the University of Illinois and the University of Wisconsin.

"The strong winds of last summer's storms caused damage to many cornfields. Inspections of those fields revealed that many continuous cornfields had roots severely damaged by corn rootworms," says Virgil Schmitt, ISU Extension field agronomist. "Those damaged roots have caused many growers, input suppliers and independent crop consultants to reevaluate the corn rootworm management strategies in those fields."

Webinar topics include:

  • Background and a research update on corn rootworms by Erin Hodgson, ISU professor and Extension entomologist

  • Bt resistance and corn rootworm management by Nick J. Seiter, U of I assistant professor and field crop entomologist

  • Diversifying corn rootworm management to delay Bt resistance by Bryan Jensen, entomologist at the UW-Madison's Integrated Pest Management Program

The webinar will be offered through Zoom. While there is no charge to attend, registration is required and can be completed at go.wisc.edu. After registering, participants will receive an email with instructions and a link for joining the webinar. Participants may join through their web browser, mobile phone or tablet. They will need to download a free app before joining. Participants should join the webinar at least 15 minutes in advance to ensure connections and software are working correctly.
