Molecular Mechanism of Biological Control of Trichodermaspp.

Trichoderma spp.is an effective bio-control agent for controlling fungal plant pathogen.On the basis of a brief introduction of Trichoderma and its bio-control mechanism,the interaction between Trichoderma and pathogens was summarized.Through the competition for nutrients and space,the growth and propagation of pathogens were inhibited,the hyperparasitism of Trichodermaspp.to pathogenic fungi,Trichoderma spp.produced antibiotics to inhibit or kill pathogenic fungi,Trichoderma spp.promoted plant growth and induced plant systemic resistance responses,etc,in order to provide a theoretical guidance for the role of Trichoderma spp.in biological control mechanisms for plant fungus diseases.
