Isolation and Screening of Antagonistic Fungi against Colletotrichum gloeosporioides

In order to prevent and control oil-tea anthracnose,pathogen strain was isolated from the leaves and fruits infected by oil-tea anthracnose.According to the Kohn's rule and morphological characteristics,the strain was pathogen of oiltea anthracnose,and it was identified as Colletotrichum gloeosporioides.Three strains of fungi with strong antagonistic action to C.gloeosporioides were obtained from oil-tea leaves collected through isolation and screening,the NO.of which were C5,S2,H18,respectively.The inhibition rates of three strains against C.gloeosporioides were 60.7%,60.0% and 58.0%,respectively.
