Description

POLYVERSUM WP is a product containing a living organism, intended to protect the root and above-ground zones against fungal diseases.

The non-pathogenic fungus Pythium oligandrum is a parasite of some pathogenic fungal species.

Pythium oligandrum decomposes the hyphae of pathogenic fungi through enzymatic breakdown, while simultaneously stimulating the immune mechanisms of the protected plant by introducing phytohormones as well as phosphorus and sugars into them. This stimulation begins during direct contact between the mycelium and young plant tissue.

POLYVERSUM WP Active substance content: 10⁶ oospores of the fungus Pythium oligandrum per 1 gram of product.

The product is intended for use with field sprayers, orchard sprayers, steam generators, as well as for watering and soaking plants.
