Farmers' unions and green activists have strongly opposed the ongoing field trials of genetically modified Bt maize in Haryana, demanding immediate suspension of such trials. Bhartiya Kisan Union on Wednesday threatened to launch a state-wide agitation against the move, claiming that many states, including Rajasthan, Uttar Pradesh and Madhya Pradesh, have already denied permission for such trials. ”We may even destroy such crops,” announced Gurnam Singh, state president of BKU, adding that this is just an attempt of multinational companies to control Indian crops and agricultural operations through the genetically modified seeds and patents.
