Fungicide for protection against powdery mildew and botrytis in grapes and vegetables as well as scab in pome fruit

Product description

VitiSan® is a fungicide based on potassium bicarbonate with compelling advantages against powdery mildew and botrytis in grapes. VitiSan® also controls powdery mildew in vegetables as well as scab and sooty blotch in pome fruit.


VitiSan® is a contact fungicide with both preventive and curative effect. Upon contact with the VitiSan® spray cover spores of fungal diseases disintegrate and dry out preventing infection of the plant. Furthermore the alkaline character of VitiSan® changes pH of the plant surface to the disadvantage of the fungi. Due to its unspecific mode of action the formation of resistance to VitiSan® is not possible.
