A study of the commercial growing of Bacillus thuringiensis (Bt) cotton
in India, compares the performance of over 9,000 Bt and non-Bt cotton
farm plots in Maharashtra over the 2002 and 2003 seasons. Results show
that since their commercial release in 2002, Bt cotton varieties have

performance of cotton growers. Regional variation showed that, in a very
few areas, not all farmers had benefited from increased performance of
Bt varieties.
