Governments of cotton growing states have spiked proposals by companies to increase prices for genetically modified (Bt) cotton seeds. Makers of Bt seed have asked for a rise in the price they could charge for a 40-seed packet of the BG1 variety to Rs 850 (from Rs 650 now) and for the BG2 variety to Rs 1,050 (up from Rs 750), as input and labour costs had gone up by 35 per cent. All the governments in question — Andhra, Maharashtra, Gujarat and Punjab — have declined to do.
