VitiSan is a biological contact fungicide based on the active ingredient potassium bicarbonate. It has preventive and curative effects against a wide range of fungal diseases.

VitiSan is well suited as a preventive agent creating a “disease-inhibiting barrier” on the plant surface. The product also has a good curative effect in the early stages of infestation. Flexible miscibility and a short pre-harvest interval make VitiSan easy to integrate into IPM or residue-free spraying programs.
