Tenet WP is a highly effective biofungicide containing two strains of Trichoderma. These beneficial fungi work by colonizing soil and roots, competing with pathogenic (disease causing) fungi for space and nutrients, while also attacking the cell walls of these pathogens with enzymes. Provides preventative control of Armillaria, Fusarium, Phythophthora, Pythium, Rhizoctonia, Rosellinia, Sclerotinia, Sclerotium, and Verticillium spp.
