Plant growth promoting rhizobacteria, having multiple activities directed toward plant growth promotion vis-a -vis exhibiting bio remediating potentials by detoxifying pollutants like, heavy metals and pesticides and controlling a range of phytopathogens as biopesticides, have shown spectacular results in different crop studies. The productive efficiency of a specific PGPR may be further enhanced with the optimization and acclimatization according to the prevailing soil conditions. In future, they are expected to replace the chemical fertilizers, pesticides and artificial growth regulators which have numerous side-effects to sustainable agriculture. Further research and understanding of mechanisms of PGPR mediated phytostimulation would pave the way to find out more competent rhizobacterial strains which may work under diverse agroecological conditions.
