Abstract: Oil tea (Camellia oleifera Abel) anthracnose caused by Glomerella camelliae is a serious disease. The pathogen of anthracnose in flowers can infect young fruits directly, A bacteria, Bucillus subtillis, isolated from old back of oil tea has strong ability to occupy the place in flowers, and thus prevents the pathogen to attact fruits. The proportion of diseased fruits were reduced about 60%.Colletotrichum gloeosporioides cul. Populus can penetrete young fruits of oil tea but without any sympotoms. Spraying suspensive solution of G. camelliae spores on the fruits inoculated by C. gloeosporioides cul. populus, the germination of G.camelliae spores were inhibited. In the stand, spraying C. gloeosporioides cul. populus spores on oil tea trees, the rate of diseased fruits were reduced obviously.In the field, using the bacteria during bloom of oil tea trees and using C. gloeosporioides cul. populus in the stage of young fruits continuosly, the effect of control was more obvious. This biological control method can avoid the chemical pollution.
