Bollgard® II Performance in the Southeast – 2003

Mike Baker, Mark Braxton, Dan Pitts, and Stew Sherrick


Large scale field trials were conducted on southeastern cotton farms in 2003 to compare the efficacy of Bollgard® II for lepidopteran control. Trials were set up as field length, non-replicated strips using three treatments, a Bollgard II variety, a Bollgard variety, and a non-Bollgard variety. Each treatment was managed independently for insect control and sprayed based on local thresholds. Data was collected from trial cooperators from forty locations across the Southeast. Results from these trials, which included yield, economic inputs, boll retention, and boll damage indicated that Bollgard II demonstrates strong protection against lepidopteran insects under commercial production conditions.
