Jeremy Greene: BT cotton, commercially available since 1996, produces its own insecticide. It does not have to have an insecticide applied to it for caterpillar pests. The economic impact of BT cotton to our producers is that they do not have to spend as much money on caterpillar control. That is provided by the technology that is in the plant. They can focus their efforts on other pests, other agronomic inputs. In doing that, yields have improved, varieties have improved, production practices have improved. Extension's role has been to test those technologies and we continue to do that over the years as those technologies improve and there are very good technologies today.
