Syngenta, one of the main producers of thiamethoxam, a pesticide used to coat seeds before germination, has launched a legal challenge against the European Commission’s decision to temporarily ban the chemical overs fears it harms bees.

The Swiss seeds and pesticides producer has sought legal recourse with the European Court of Justice claiming that the EU executive had based its decision on a flawed process.

The Commission, on the advice of the European Food Safety Authority (EFSA), banned in April three widely-used pesticides known as neonicotinoids judged to pose “high acute risks” to honeybees in certain crop uses. Thiamethoxam, one of the neonicotinoids, is an active ingredient in Syngenta’s Cruiser seed treatment.

Announcing the legal challenge, the Swiss agriculture giant claimed that EFSA’s assessment was “inaccurate and incomplete” and that the Commission imposed the ban without the full support of EU countries.

Syngenta CEO John Atkin said in a statement: “We would prefer not to take legal action but have no other choice given our firm belief that the Commission wrongly linked thiamethoxam to the decline in bee health. In suspending the product, it breached EU pesticide legislation and incorrectly applied the precautionary principle.”
