Not AvailableRhizobacteria have been described as plant growth promoting as they offer their plant hosts an addit ional fortification against pathogen by expression of multiple activities that directly and indirectly inhibit pathogens. Most microbial diversity of the soil ecosystem is confined to the rhizosphere. These rhizospheric microbes have the potential to stimulate plant growth and manage soil and plant health. Nowadays, management of the rhizosphere bacterial population has advanced toward the concept of plant growth promoting rhizobacteria (PGPR) owing to emergence of fungicide-resistant pathogens and health concerns for the producers and consumers. Using PGPR as bio-fertilizer is an efficient approach to replace chemical ferti...
