True. Trichoderma is a genus of fungi known for its ability to promote plant growth and control plant pathogens through various mechanisms, including the production of secondary metabolites. These metabolites can inhibit the growth of harmful pathogens, thereby reducing infection levels in plants. This makes Trichoderma a valuable agent in biological control strategies.
The direct biological control method involving Trichoderma may be effective if secondary metabolites that can inhibits the growth oof pathogens and reduce infection levels in plants are produced.
