Two interactions between Pseudomonas and plants have attracted significant attention: plant parasitism by plant pathogenic Pseudomonas syringae ; and stimulation of plant growth and induced systemic resistance (ISR) by plant growth‐promoting Pseudomonas fluorescens and Pseudomonas putida (66; 49). However, exploiting the benefits of PGPRs requires knowledge of bacterial function and an in-depth understanding of plant-bacteria associations.

Diverse mechanisms are involved in the suppression of plant pathogens, which is often indirectly connected with plant growth. Among the method of application tested in our study, soil application was found to be the best in yielding better results of plant growth promotion. P > 0.05.

A free living Plant growth promoting rhizobacteria (PGPR) Pseudomonas fluorescens are able to colonize around plant root and incorporate free atmospheric molecule into plant absorbable nutrient form along with improved plant growth and crop yield. Many of these rhizobacteria are symbionts and provide plant growth promotion (PGP) services, protecting the plant from biotic and abiotic stresses and increasing plant productivity by providing access to nutrients that would otherwise be unavailable to roots. A promising alternative to agrochemicals is the use of plant growth-promoting rhizobacteria (PGPR), which are commonly associated with many, if not all, plant species.
