Abstract: Trichoderma spp. are widely studied biological control agents (BCA) and have been used worldwide for plant disease control. The application and control efficiency of Trichoderma in control of plant diseases was reviewed in this paper. The multiple biocontrol mechanisms of Trichoderma against pathogens, including competition, mycoparasitism and antifungal activity, as well as the interaction with plant (plant growth promotion and induced resistance), were summarized. More than 250 Trichoderma-based bio-products have been commercialized and successfully used in different area of the world, exploration of more potential Trichoderma isolates by screening or genetic improvement are still processing. The researches of Trichoderma-based biocontrol and the mechanism have outstanding contributions to the application of biocontrol and the reduction of chemical fungicide use.

Key words: Trichoderma, plant disease, biological control, Trichoderma-based commercial products
