Abstract：In order to obtain bio-control endophytic bacteria, sixteen endophytic bacteria were isolated from Areca catechu L. by conventional surface disinfection method. The strain BLG1 showed excellent antimicrobial activities,especially,the inhibition rate against Rhizoctonia solani reached 95. 00%. Crude extracts from endo- and extra-cell of the strain were tested, and the result showed that the active components mainly were distributed in extracellular part extracted by n-butyl alcohol. Pot experiment test showed that the strain BLG1 had good control effect (67. 05%) against Rhizoctonia solani,which was the same as 10% Jinggangmycin aqueous solution (66. 47%). Therefore,the strain BLG1 has values of further research and development.
