Abstract: 

In a survery conducted in 2000, 184 bacterical is olates were collected from rhizosphere of different rice fields. To assess, Their antagonistic activities against Rhizoctonia solani To assess their antagonistic activities,all strains were screened against R. solani usingPark test in dual cultures. Results showed that 47 isolates mostly belong to Gram-posivtive bacteria and some fluorescent pseudomonads, the antagonistic bactera were identified as The strains encoded 5, 93, Ifu, B29 and T42 were identified as Pseudomonas fluorescens, strain 24 as Bacillus cereus, strains 29 and 120 as B. subtilits,on the basis of biochemical, physiological and morphologicaland characters. Of these, strains with strong and promising antagonistic activity were select for further studies. In total Strains 5, 93, T42, 24, 29, 120 inhibited normal mycelia growth of the fungus, whereas the strains 5 and T42 showed super antagonistic activities. In greenhouse trial, both bacterial strains as well as Tilt treatments did reduced variably sheath blight of rice plants. All strains infirst and second experiments could promote the plant height, whereas strains both of 5, T42 could increase the numbers of tillages. Increasing the root length by strain T42 and plant dry weights by strains 5, 93, T42, 24 were some othere promising results, otained in these experiments.
