Kolkata Govt creating buffer zone near Indo-Bangla border to combat wheat blast In the wake of the deadly wheat blast disease destroying wheat on 8,00 hectare land in Nadia and Murshidabad earlier this year with the fungus sneaking in from Bangladesh, the state government is creating a buffer zone in the border area to prevent the entry of any contaminated crop from the neighbouring country. The state has already banned wheat cultivation within five km from the Bangladesh border and ensure that the farmers in the borders who cultivated wheat on that affected land in the two districts produce crops of such nature that have minimum chances of contamination. We are holding talks with experts seeking their opinion on the nature of crops that can be cultivated there. Pulses can be an option as it needs less water. There is usually paucity of water in the border.
