Abstract
The objective is to present the economic
impact of producers adopting Bt cotton and the rapid
diffusion on the main producing countries: USA, China
and India. The existing literature about this type of
transgenic crop has been revised and the results of
different research are presented. Bt cotton varieties have
been quickly adopted by the countries in this study. Data
show that this technology helps reduce production losses
and significantly decrease the use of pesticides, thus
saving their cost and the associated labour cost. But the
total cost reduction is weak due to the high prices of the
seeds incorporating this technology.
