The cotton crop in Haryana, especially Bt cotton, is under threat from mealy bug, which may cause extensive damage to the crop if not controlled in time, said sources in the Haryana Agriculture Department. In the past, the cotton crop in the state had often been damaged by the American Bollworm. [...] However, now a threat by another bug looms large. It was generally believed that Bt cotton was pest-resistant, but B.S. Duggal, Additional Director, Haryana Agriculture, says Bt cotton is safe only from bollworm and not mealy bug.
