GM Bt cotton has failed in India – new study

Researchers find GM Bt cotton leads to stagnant yields, high costs, increased insecticide use, low farmer incomes and farmer suicides

The conclusion of this study on GM Bt cotton in India speaks for itself: "The hybrid long-season Bt technology for rainfed and irrigated cotton is unique to India, and is a value capture mechanism. This technology is suboptimal, leading to stagnant yields, high input costs, increased insecticide use, and low farmer incomes that increase economic distress that is a proximate cause of cotton farmer suicides. The current GM Bt technology adds costs in rainfed cotton without commensurate increases in yield. Non-GM pure-line high-density short-season varieties could double rainfed cotton yield, reduce costs, decrease insecticide use, and help ameliorate suicides. The GM hybrid technology is inappropriate for incorporation in short-season high-density varieties."
