Insect Management

The risk of developing insect resistance is real but may be reduced with proper planning. To help preserve the effectiveness and benefits of Bacillus thuringiensis ("B.t.") technology, growers are required to develop and follow an insect resistance management ("IRM") plan.

Growers who purchase corn seed (and in some cases cottonseed) that contains B.t. technology must plant a refuge as part of their IRM plan. Refuge size, configuration, and management are described in detail in the IRM Grower Guide found on corn seed bag tags and in the Corn and Cotton sections of the Bayer TUG.
