In a major setback to the proponents of genetically modified technology in farm crops, the Parliamentary Committee on Agriculture on Thursday asked the government to stop all field trials and sought a bar on GM food crops (such as Bt. brinjal). The committee report, tabled in the Lok Sabha, demanded a ”thorough probe” into how permission was given to commercialise Bt. brinjal seed when all evaluation tests were not carried out. It said there were indications of a ”collusion of the worst kind from the beginning till the imposition of a moratorium on its commercialisation in February, 2010, by the then Minister for Environment and Forests.”
