The modern agricultural system has issues with the reductionofagricultural productivity due to a wide range of abiotic and bioticstresses. It is also expected that in the future the entire worldpopulation may rapidly increase and will surely demand more food.Farmers now utilize a massive quantity of synthetic fertilizers andpesticides for disease management and to increase food production.These synthetic fertilizers badly affect the environment, the textureof the soil, plant productivity, and human health. However, agriculturalsafety and sustainability depend on an ecofriendly and inexpensivebiological application. In contrast to synthetic fertilizers, soilinoculation with plant-growth-promoting rhizobacteria (PGPR) is oneof the excellent alternative options. In this regard, we focused onthe best PGPR genera, Pseudomonas,which exists in the rhizosphere as well as inside the plant'sbody and plays a role in sustainable agriculture. Many Pseudomonas spp. control plant pathogens and play an effective role in diseasemanagement through direct and indirect mechanisms. Pseudomonas spp. fix the amount of atmospheric nitrogen, solubilize phosphorusand potassium, and also produce phytohormones, lytic enzymes, volatileorganic compounds, antibiotics, and secondary metabolites during stressconditions. These compounds stimulate plant growth by inducing systemicresistance and by inhibiting the growth of pathogens. Furthermore,pseudomonads also protect plants during different stress conditionslike heavy metal pollution, osmosis, temperature, oxidative stress,etc. Now, several Pseudomonas-based commercial biologicalcontrol products have been promoted and marketed, but there are afew limitations that hinder the development of this technology forextensive usage in agricultural systems. The variability among themembers of Pseudomonas spp. draws attention to thehuge research interest in this genus. There is a need to explore thepotential of native Pseudomonas spp. as biocontrolagents and to use them in biopesticide development to support sustainableagriculture.
