Headquarters Press Release Washington, DC. Date Published: 01/14/2000 Title: Bt. CORN INSECT RESISTANCE MANAGEMENT ANNOUNCED FOR 2000 GROWING SEASON FOR RELEASE: FRIDAY, JAN. 14, 2000 Bt. CORN INSECT RESISTANCE MANAGEMENT ANNOUNCED FOR 2000 GROWING SEASON EPA has announced new measures for resistance management in Bt. corn. The additional measures to fully manage insect resistance for the 2000 growing season include: registrants must require that growers plant a minimum structured refuge of at least 20 percent non-Bt. corn; for Bt. corn grown in cotton areas, registrants must ensure that farmers plant at least 50 percent non-Bt. corn; registrants will expand monitoring in the field as an early warning system to detect any potential resistance, and will communicate voluntary measures that will protect non-target insects, particularly the Monarch butterfly; and there will be sales and planting restrictions in certain limited geographic areas for some products. The industry has agreed to the Agency's conditions. For more information on EPA's biotechnology regulatory program for plant pesticides, see: http://www.epa.gov/pesticides/biopesticides.
