New requirements for Bt corn

The EPA has proposed framework intended to delay the corn rootworm pest from becoming resistant to Bt corn.


Here are the proposed requirements on the manufacturers of Bt corn:


  • In areas at risk of corn rootworm resistance, require crop rotation; use of corn varieties containing more than one Bt toxin; or other Integrated Pest Management (IPM) strategies and stewardship for corn rootworm.
  • Develop and implement a strategy to better detect and address areas of resistance as they emerge.
  • Use different and improved scientific tests and sampling requirements to study the problem and more reliably ensure that resistance to the Bt corn toxin is identified.
