As the rapid development of Genetically Modified crops, Chinese government has been increasing its efforts in GM crop biosafety management. However, the rapid expansion of Bacillus thuringiensis (Bt) cotton varieties and less regulated seed industry also resulted in a large amount of Bt cotton...

The overall goal of this study is to determine the extent by which genetically engineered (GE) crops in China can lead to reductions of pesticide use, the nature and source of the reductions, and whether or not there are any non-pecuniary externalities. One of the first studies of the effect of...

A sample of 283 cotton farmers in Northern China was surveyed in December 1999. Farmers that used cotton engineered to produce the Bacillus thuringiensis (Bt) toxin substantially reduced the use of pesticide without reducing the output/ha or quality of cotton. This resulted in substantial...
