The United States Environmental Protection Agency (EPA) has made specific insect resistance management recommendations and requirements as part of the BollgardJ cotton registration since 1995. Refuge size, structure, and deployment are important to the success of the high dose/structured refuge strategy. New insect resistance management requirements that focus on deployment and structure of the refuge for BollgardJ cotton go into effect for the 2001 growing season. These requirements are: 95:5 external unsprayed refuge (at least 150 feet wide and planted within 1/2 mile), 95:5 embedded refuge (at least 150 feet wide), and 80:20 external sprayed refuge (planted within 1 mile, but preferably within 1/2 mile). Other refuge strategies are also under consideration. EPA will continue to examine the insect resistance management requirements as part of its current reassessment of the human health and environmental risks associated with BollgardJ cotton. The current registration for BollgardJ cotton expires September 2001. |
