The European Union’s top court has upheld the EU’s partial ban on three insecticides linked to harming bees, preventing their use on certain crops. The European court of justice on Thursday dismissed an appeal by Bayer to overturn a lower EU court’s 2018 decision to uphold the ban. The ruling covers three active substances – imidacloprid, developed by Bayer CropScience, clothianidin, developed by Takeda Chemical Industries and Bayer CropScience, as well as Syngenta’s thiamethoxam. A Bayer spokesperson said it was disappointed by the verdict and stood by the safety of the products, which continue to be used in other regions with appropriate risk mitigation measures applied. “The verdict seems to allow the (European) Commission almost carte blanche to review existing approvals upon the slightest evidence, which need not even be new scientific data,” the spokesperson said. The commission in 2013 restricted the use of the neonicotinoids, meaning they could not be used on maize, rapeseed and some spring cereals. They could still be used for other crops, such as sugar beet. The commission had reviewed the approvals because of the loss of bee colonies due to the misuse of pesticides. Bayer had said there was insufficient new scientific knowledge to justify the restrictions. The EU’s highest court on Thursday dismissed that appeal and ordered Bayer to bear its own costs plus those of other parties. “The court of justice has reaffirmed that protecting nature and people’s health takes precedence over the narrow economic interests of powerful multinationals,” said the Greenpeace legal strategist Andrea Carta. Bayer and ChemChina-owned Syngenta had warned that banning the insecticides would mean farmers would revert to older chemicals and increased spraying. Despite the ban, 206 emergency authorisations were granted for the use of the substances in the EU between 2013 and 2019. EU auditors last year said this pesticide use, while legal, was thought to be responsible for honeybee losses. To protect bees, the commission has proposed targets to cut the EU’s use of chemical pesticides by 50% and to reduce fertiliser use by 20% by 2030.
