摘要：

This paper describes the method and findings of a survey designed to explore the economic bene fits of the adoption of Bacillus thuringiensis (Bt) cotton for smallholder farmers in the Republic of South Africa. The study found reason for cautious optimism in that the Bt variety generally resulted in a per hectare increase in yields and value of output with a reduction in pesticide costs, which outweighed the increase in seed costs to give a substantial increase in gross margins. Thus, these preliminary results suggest that Bt cotton is good for smallholder cotton farmers and the environment.
