The paddy soil samples used for bacterial iso-lation were collected from different counties ofJiangsu and Anhui Provinces.Nine hundred andfifty-one bacterial isolates were obtained by dilu-tion isolation.All these isolates were tested fortheir ability in inhibition against Rhizoctonia solaniand Fusarium moniliforme in vitro.The resultsshowed that the isolates possessing antagonisticability against R.solani and F.moniliforme were 60 The paddy soil samples used for bacterial iso-lation were collected from different counties of Jiangsu and Anhui Province.
