ABSTRACT

Studies were carried out from 2013 to 2015 with the objectives to isolate and identify some indigenous rhizobacterial strains against major soil-borne pathogens of brinjal. Seventy thizobacterial isolates were characterized based on colony characters, morphological and biochemical test and identified as Pseudomonas flourescens (30), P. aeruginosa (13), P. aureofaciens (2) and Bacillus subtilis (25). In vitro bioassay of the seventy rhizobacterial isolates revealed that the isolate I-58 was the most effective rhizobacterial isolate, followed by I-30 and I-55 isolates in inhibiting the radial growth of test pathogens.
