Summary

Survey-based study of chemical usage and yield in Bt and non-Bt cotton in the southern US. Difference in yields in favor of Bt cotton. Only significantly affected pesticide use in a few of the cases. Adoption of Bt decreased the application of insecticides that were normally targeted by Bt. Adoption of Bt cotton did lead to a significant increase of usage of insecticides targeted at insects that were not targeted by Bt
