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