Abstract
AbstractA comparative analysis of conventional and insect protected or “Bt” cotton varieties in farmers fields in the Argentine cotton production area during the 1999/00 and 2000/01 growing seasons was conducted. Use of Bt cotton provided farmers with benefits such as increased crop yields and a considerable reduction in the number of insecticide applications. The average additional benefit obtained in both growing seasons was 57.98 $/ha, equivalent to 16 US$ (July 2002).Key Words: Transgenic Bt cottoneconomic benefitdirect cost incomesinsecticide useArgentina
