Single-gene Bollgard technology and related variety types (B and BR) expires September 30, 2009. Over 90% of Georgia's cotton acreage is planted to BR (Bollgard® plus Roundup-Ready®) technology. Approximately 86% of the state is planted to a single variety- Deltapine 555 BR which has offered a strong and consistent yield advantage compared to other varieties. Georgia producers have not embraced available two-gene technologies Bollgard II (B2) and Widestrike (W). Upon expiration of single-gene Bollgard technology and producers then having to switch to other technology(ies), in addition to any yield and fiber quality effects, cost of production could also change. Such cost changes could include seed and associated technology fees, insect control, and weed control. Cost estimates conducted for this study conclude that total seed and technology-related production costs for two-gene varieties could be similar to DP555BR. Yield will likely continue to be the major factor in choosing a variety after expiration of single-gene Bollgard technology. Two-gene technology packaged with Roundup-Ready Flex offers added protection and management flexibility for the producer. In terms of cost, however, differences in cost per acre are relatively minor in terms of yield. Yield will likely be at least as important as any other factor as Georgia cotton producers decide how to adjust to the loss on single-gene Bollgard technology. [ABSTRACT FROM AUTHOR] |
