Laboratory and greenhouse experiments (using sterile and non- sterile soil) were conducted at the potato brown rot project (PBRP), Giza, Egypt to evaluate the ability of some strains of plant growth promoting rhizobacteria (PGPR) to control the pathogen microorganism causing potato brown rot disease. Two bacterial strains (Ralstonia solanacearum) were isolated from naturally infected potato tubers and identified by PCR and Real - time PCR technique as Ralstonia solanacearum race 3 biovar 2. Results of the antagonistic activity of the tested bio - agents against Ralstonia solanacearum showed that all of the tested PGPR strains exhibited variable antibacterial effects against ralstonia solanacearum
