French growers concern over copper restrictions

French winegrowers are voicing strong concerns over tighter restrictions on copper-based products, vital for controlling vineyard diseases. Organic producers warn the new rules could force them to abandon sustainable practices amid rising climate-related risks.

Producers say the move by France’s health agency, Anses, which will block 17 copper-containing products from 2027, threatens the tools they rely on to fight downy mildew. While the sector has already halved its copper use over the last 20 years, growers argue that wetter seasons demand more, not less, treatment. Organic representatives warn the restrictions could push some to abandon organic farming entirely.

Groups, including FNAB and France Vin Bio, are calling for regulatory support and plan legal action alongside manufacturers. Anses maintains copper is essential but toxic in excess, highlighting the challenge of balancing environmental safety with practical vineyard needs. The debate could reshape organic wine production across France.
