PARIS 鈥 France鈥檚 constitutional court blocked the re-introduction of a pesticide accused of harming bees, in the latest twist in a fierce political battle in the European Union鈥檚 biggest agricultural producer.

The court said the re-authorization of acetamiprid, part of the neonicotinoid group of pesticides banned in France, as proposed under a farming bill passed last month did not provide sufficient safeguards on the use of the crop chemical.

The planned relaxation of France鈥檚 neonicotinoid ban fueled opposition to the legislation, with a petition against it gathering over 2 million signatures, a record for a petition on the website of France鈥檚 National Assembly.

The court鈥檚 ruling is a setback for supporters, including most of France鈥檚 farming unions and conservative politicians, including Senator Laurent Duplomb who gave his name to the bill.

They had argued that acetamiprid is authorized elsewhere in Europe, as it does not pose the same risks as other neonicotinoids banned at EU level, and without it crops like sugar beets and hazelnuts face severe disease losses.

However, the FNSEA and JA, two of France鈥檚 main farmer unions, welcomed the court鈥檚 approval of most of the legislation, including steps to simplify planning permission for livestock buildings and water reservoirs for irrigation.

President Emmanuel Macron, whose centrist allies in parliament were divided over the legislation, would sign the bill into law 鈥渁s soon as possible鈥 in line with the court鈥檚 decision, the Elysee said. 鈥 Reuters
