Lower copper limit for organic wine producers. Maybe.

Being an organic winegrower means that you are obliged to spray with copper to prevent certain fungal diseases rather than using synthetic pesticides. Copper is effective primarily against mildiou.

Will copper be the next victim of the organic wave?

Copper and substances containing copper are frequently used to fight mildew. It is even permitted in organic farming (even though it can hardly be claimed to be a “natural” treatment).
