Chaetomium spp. are isolated, identified and screened to control plant pathogen isolated in China. Disease interacting pathogens were found in peach diseases which were Pythium, Rhizoctonia solani (twig die back), Fusarium spp (wilt) Phomopsis, Colletotrichum dematium, Colletotrichum gleosporiodes, Phoma, Fusarium, Fusarium, Phomopsis, and Alternaria. The main primary organism caused infection to peach supposing to be Phomopsis and Fusarium destroying roots and vascular bundle, and the pathogens infected above peach tree in stem, twigs and leaves found Colletotrichum dematium, Colletotrichum gleosporiodes, and Alternaria. Bi-culture test between Chaetomium antagonistic fungus and phytopathogens was evaluated to know the control mechanism which tended to give good results. Futher testing bioproduct of Chaetomium had been also tested in tea, peach, grape and old trees with different phytopathogenic isolates and reveiced a good result to control and recovery plants from disease incidence.
