Plant growth promoting rhizobacteria (PGPR) were isolated from rhizospheres of coleus (Coleus forskohlii) and ashwagandha (Withania somnifera) from different parts of Karnataka. Isolated PGPR strains were screened for their efficacy against three soil-borne pathogens like Fusarium, Ralstonia and Meloidogyne in coleus and ashwagandha. Meloidogyne incognita causes root-knot disease complex and in conjunction with other two pathogens. Plant growth promoting activity of rhizobacteria having been tested, their phenotypic as well as biochemical characterization of these potent PGPR strains showed them to be fluorescent pseudomonads. Talc-based bioformulations of these fluorescent pseudomonads were utilized in replicated pot and field experiments to determine their efficacy to suppress the disease complex and enhance plant growth parameters of coleus and ashwagandha. Among the seven potent strains RB-50 and RB-31 decreased root knot index and incidence of disease complex while increasing plant height, number of branches, fresh and dry biomass; tuber yield in respect of both coleus and ashwagandha.
