This picture taken on June 15, 2015 shows a bottle of Monsanto’s ‘Roundup’ pesticide in a gardening store in Lille. French Ecology Minister Segolene Royal announced on June 14, 2015 a ban on the sale of American biotechnology giant Monsanto’s popular weedkiller from garden centres, which the UN has warned may be carcinogenic. The active ingredient in Roundup, glyphosate, was in March classified as “probably carcinogenic to humans” by the UN’s International Agency for Research on Cancer (IARC).
