New Requirements to Address Corn Rootworm Resistance to Bt Corn

In response to signs that the corn rootworm is becoming resistant to single trait Bt products, the Environmental Protection Agency is announcing new, more protective requirements designed to delay corn rootworm resistance to genetically engineered “Bt corn.” Bacillus thuringiensis (Bt) corn produces a Bt pesticide, long used as part of organic farming, as part of the plant itself, to address corn rootworm pests.

When EPA registered Bt corn, EPA ensured that mid-course corrections could be made if additional restrictions on the use of the pesticide were needed to address evolving issues. For example, these corrections could include requirements for additional measures or use restrictions if a specific Bt pesticide begins to lose its effectiveness to kill the corn rootworm. EPA is adding additional requirements to delay pests from becoming resistant.   Continue reading
