The modern agricultural system has issues with the reduction of productivity due to a wide range abiotic and biotic stresses. It is also expected that in future entire world population may rapidly increase will surely demand more food. Farmers now utilize massive quantity synthetic fertilizers pesticides for disease management food production. These badly affect environment, texture soil, plant productivity, human health. However, safety sustainability depend on an ecofriendly inexpensive biological application. In contrast fertilizers, soil inoculation plant-growth-promoting rhizobacteria (PGPR) one excellent alternative options. this regard, we focused best PGPR genera, Pseudomonas, which exists rhizosphere as well inside plant's body plays role sustainable agriculture. Many Pseudomonas spp. control pathogens play effective through direct indirect mechanisms. fix amount atmospheric nitrogen, solubilize phosphorus potassium, produce phytohormones, lytic enzymes, volatile organic compounds, antibiotics, secondary metabolites during stress conditions. compounds stimulate growth by inducing systemic resistance inhibiting pathogens. Furthermore, pseudomonads protect plants different conditions like heavy metal pollution, osmosis, temperature, oxidative stress, etc. Now, several Pseudomonas-based commercial products have been promoted marketed, but there are few limitations hinder development technology extensive usage systems. variability among members draws attention huge research interest genus. There need explore potential native biocontrol agents use them biopesticide support
