Trichoderma is a genus of fungi that is commonly found in the soil and rhizosphere region. It is a biocontrol agent that is used to control a variety of soil-borne pathogens by producing toxic metabolites. Trichoderma is mainly used to control soil-borne diseases as well as some leaf and panicle diseases of various plants. It is also used to stimulate plant growth by improving the growth of seedlings and causing resistance against abiotic stress. Trichoderma secretes an enzyme that dissolves the cell wall of other fungi, which allows it to get inside and consume them. It is effective against pathogens causing various diseases of the root region of plants, such as collar rot, foot rot, and damping off. Trichoderma is different from seed-applied fungicides because it multiplies on its own and grows to continually cover the roots, protecting them for the whole growing season. Overall, Trichoderma is used for biocontrol of fungal phytopathogens and stimulation of plant growth in agriculture.
