[Objective] The aim was to explore the interaction between fungi separated from leaves of tea gardens and Colletotrichum camellia.[Method] The method of plate confrontation culture was used to culture the fungi and C.camellia.The interaction between fungi separated from leaves of ecological tea garden and ordinary tea garden and C.camellia were studied through comparison.[Result] According to the effect of leaf fungi on the pathogens,the pathogen could be divided into 3 kinds of antagonistic fungi,symbiotic fungi and assistant fungi.The composing proportion of the 3 kinds of fungi in the 2 tea gardens had no obvious difference.The 3 kinds of fungi in the ordinary tea garden were 72.9%,5.1% and 22.0%,resp.and that in the ecological tea garden were 72.5%,4.4% and 22.1%,resp.The strains with weak antagonism on in the ordinary tea garden were dominant strains,which were 9.8% higher than that in the ecological tea garden,but the proportion of the strains with strong antagonism in the ordinary tea garden was 7.4% lower than that in the ecological tea garden.The constitution of strains with obvious promotion effect on C.camellia in the 2 tea gardens was not same,that in the ecological tea garden was 6.8% and 5.9% in the ordinary tea garden.[Conclusion] The research provided theoretical basis for the biological control of tea garden diseases.
