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 fluorescent pseudomonads for the management of coleus and ashwagandha root diseases
