OSO 5%SC Fungicide - 1 quart

Preventative or curative treatment of fungal diseases, including Botrytis, Alternaria, Anthracnose, Powdery Mildew, Botrytis, and leaf and fruit rots in fruit and vegetable crops.

The active ingredient of OSO® is polyoxin D zinc salt derived from a natural fermentation process. Polyoxin D zinc salt is a chitin synthase inhibitor that controls plant pathogenic fungi by inhibiting the formation of chitin, a vital component of fungal cell walls. When the pathogen comes in contact with OSO, early growth or colonization is stopped and cannot spread to new plant tissue.

Effective against a wide range of diseases in a wide range of crops. Please see the label and technical sheet for more information.
