Eminent scientist P.M. Bhargava Friday called for a moratorium of at least 15 years on genetically modified (GM) crops in the country. [...] ”Only after extensive research should any GM product be considered as a commercial product in the country. Whenever a drug is to be launched, it requires 15 years of testing period. However, the drugs can still be recalled from the market. But the plants once released can’t be recalled,” he said.
