However, not everybody agrees with this strategy. Govind Gujar, who retired as the head of entomology at the Indian Agricultural Research Institute, says moving back to BG is a bad idea because the problem was not with the BG trait but with long-duration cotton. And even if BG-2 doesn’t fend off the pink bollworm, it still protects against other pests like the tobacco cutworm and the American bollworm. The presence of two Bt genes in BG-2 means it will be more effective than BG in delaying resistance against these pests. He asks: When the whole world is moving to BG-3, why do we want to go back in time? The more critical question is, even if the government incentivises a return to BG, will all seed companies stop making BG-2 seeds? Some, like the Hyderabad-based Nuziveedu Seeds, say they will. But others, like the Aurangabad-based Ajeet Seeds, prefer BG-2 because of the superior stacked gene technology. If India cultivates both BG and BG-2, simultaneously, that can accelerate resistance among pests, studies predict. This could trigger the emergence of new cotton pests. India erred by not clamping down on long-duration crops when Bt cotton was first introduced. At least now it must base its policy on sound science and implement it stringently.
