Technology and US Farm Policy changes are producing the most rapid and significant changes in cotton IPM systems in the last 20 years. Bt cotton, boll weevil eradication, new insecticide chemistry, and large fluctuations in crop averages have set the stage for this rapid, large scale change. The evolving new cotton production/cotton IPM systems will require a variety of system components. In some production systems ovicides will be used for cheap effective reductions in worm hatch while preserving beneficial arthropods and providing resistance management benefits. Ovicides may take on a larger role post-eradication and in Bt cotton to control worms, and maintain insecticide susceptibility in worm populations without decimating natural enemies. They may be increasingly used in Bt cotton during the bollworm susceptible bloom stage for low cost worm suppression and resistance management.
