Abstract:: Some rhi zobacteria w ere chosen to test their a bili ty to suppress so ybean cy st nematodein ma tural soi l which had been infested by SCN for sev era l years ( 50 cy st s /100gdry soi l) in the g reenhouse. Four o f them, namely JN JQ1- P( 1) , JN JQ1 - A5- 1 , SYNS and QSG- LD- 6, showed promising cont rol ef ficacy , the number of SCN o n soybean ro ot s w as reducedov er71. 8% ( p= 0. 01) , 69. 3% ( p= 0. 01) , 65. 8% ( p= 0. 05) a nd 57. 5% ( p=0. 05) by those 4 iso lates. The seco nd stag e juv eniles of SCN w ere killed when treatedw ith fementatio n solution of four bacteria abov e 93. 3% .
