France bans copper fungicide powders

France’s food safety agency Anses has revoked authorisation for 20 copper-based fungicides, a move that could significantly impact organic viticulture. Only two products remain approved under strict new rules.

The decision by Anses, announced via Vitisphere, targets all powdered copper products including widely-used brands such as Kocide 2000 and Kocide Flow. While Champ Flo Ampli and Héliocuivre are still allowed, usage limits include a 4kg/ha annual cap, minimum seven-day intervals between treatments, and buffer zones near homes and water. Application during flowering is now prohibited.

The agency cited health risks to vineyard workers and inadequate safety data from manufacturers. The ban is especially controversial as many growers had returned to powdered forms due to cost pressures.

French organic producers fear the changes could push them back toward conventional farming. Meanwhile, German organic growers aren't expecting similar restrictions. With more products up for renewal, further bans could follow in 2026.
