The risk of 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 follow an Insect Resistance Management (IRM) plan. Growers must read the IRM Grower Guide prior to planting for details on planting a refuge, geographical restrictions, and other requirements of the IRM Plan.
