Environmentalists scored a victory in Canada on Wednesday, securing restrictions on two pesticides that have been posing threats to bees and aquatic insects. The Canadian government’s Pest Management Regulatory Agency (PMRA), branched under the division ‘Health Canada,’ has agreed to impose constraints on the crop chemicals, slowly phasing out their use over the next three to five years. Thiamethoxam, produced by Syngenta AG, and Bayer AG’s clothianidin are common farming applicants to protect crops such as corn, soybeans and canola from damage caused by insects.
