The increasing demand of the agricultural produce can be attained by optimizing the productivity potential and by minimizing the losses caused by notorious plant-parasitic nematode of the crops. Chemical based nematode control is an effective strategy to combat this biotic stress, but inappropriate and inadequate application of synthetic pesticides has exerted an adverse effect on bio-flora, fauna and natural enemies. Due to the environmental and regulatory pressure, use of potential biocontrol agents is the most welcomed way for nematode management by the farming community. There is an emerging market for Plant growth promoting rhizobacteria (PGPR) mediated eco-friendly biopesticides for plant-parasitic nematode biocontrol. Moreover, PGPR strains can enhance the plant growth through the production of various plant growth promoting substances. Based on the fact stated above, the present review focused on PGPR based nematodes biocontrol strategies, the direct and indirect mechanism of PGPR for nematode biocontrol and future prospect of PGPR based biocontrol agents against nematodes are discussed.
