Dr. Hornby's Piranha colonizes the root zone with 24 beneficial fungi. These fungi are 8 species of trichodermia and 16 species endo and ecto mycorrhizal. Trichodermia are very aggressive colonizers that enhance root mass, and provide excellent control from root rot, pythium and pytophethoria.
Dr. Hornby's Piranha Beneficial Fungi is an effective foliar spray against fungi that attack plant foliage. (ie. Pythium spp., Rhizoctania solani, Fusarium spp., Botrytis cinerea (bud rot), Sclerotium rolfsii, and Sclerotinia homoeocarpa)
The mycorrhizal fungi excrete powerful
chemicals that dissolve mineral nutrients,
absorb water, retard soil pathogens,
and glue soil particles together into
porous structure. Mycorrhizal can expand
the surface area of the root mass by 700%.
Both plant and fungus benefit from the
symbiotic relationship.
