Trichoderma harzianum strain T-22 is a fungus that protects plants from disease-causing fungal pathogen. It is a beneficial fungus that out competes plant pathogenic fungi for space and nutrients, colonizing the plant roots ahead of the pathogens. It also acts as a mycoparasite by producing enzymes that break down the hyphae of the plant pathogenic fungi. The mechanisms of biocontrol with T. harzianum are complex and generally considered in competition with plant pathogens for space and substrates in the rhizosphere, mycoparasitism and the secretion of cell wall degrading enzymes, production of antifungal substances, and induction of systemic resistance.
