One promising method to reduce the use of chemical fertilizers is the application of plant growth-promoting rhizobacteria PGPR as microbial inoculants in agriculture.
Antagonistic activity of plant growth promoting rhizobacteria isolated from tomato rhizosphere against soil borne fungal plant pathogens. Views Read Edit View history. The motility of the bacteria was checked using hanging drop method. A new, naturally occuring soil bacterium that offers control of a wide range of plant fungal pathogens.
Its ability to exhibit various PGP traits at higher temperature shows that the isolate may prove effective as an inoculant.
