Abstract

Pseudomonas fluorescens is Plant Growth Promoting Rhizobacteria that aggressively colonize the root zone and promote plant growth are generally termed as Plant Growth Promoting Rhizobacteria (PGPR). P. fluorescens act as biocontrol agents as well as plant growth promoter as it produces different types of secondary metabolites likes iron chelating siderophores exoenzymes, phytohermones, antibiotic which helps to adopts the plants from various diseases and stressed conditions. It also induces systemic resistance. This review was carried on mechanisms of bio-control agent Pseudomonas fluorescens against plant pathogens, plant-growth-promoting qualities, plant-growth-promoting methods, antibiosis through production of antibiotics and secondary metabolites, act as competition for space and nutrients and the induction of systemic resistance by plant-growth-promoting rhizobacterium (PGPR) against several plant diseases and nematode pests. The article discusses the causes of induced systemic resistance to a variety of plant pathogens that cause bacterial, viral, and fungal illnesses as well as nematode pests

Conclusion

In the last few years, significant progress has been made in our understanding of how Pseudomonads fluorescens colonizes roots and the various ways in which it can suppress soil-borne phytopathogens. In the 21st century, remarkable progress has been made in the biotechnology of P. fluorescens as a biocontrol agent for the defense of crops. Chemical pesticides do not need assistance for proper establishment in the soil rhizosphere, while biocontrol agents do even after application. Therefore, in order to ensure biocontrol, it is important to consider the biocontrol agent's quality as well as how it competes with other pathogens. Future applications for P. fluorescens as a biocontrol agent and a plant growth promoter in sustainable management techniques are extremely promising. The main drawbacks of P. fluorescens in biocontrol are its short shelf life and inconsistent performance in different environments, both of which can be improved by future research efforts
