The Pf-5 strain resides in the plant’s rhizosphere and produces a variety of secondary metabolites including antibiotics against soil borne plant pathogens. and Ustilogo spp. Pseudomonas fluorescens are Gram-negative rod shaped bacteria that inhabit soil, plants, and water surfaces. Pseudomonas fluorescens is an aerobic, gram-negative, ubiquitous organism present in agricultural soils and well adapted to grow in the rhizosphere. ... Pseudomonas fluorescens and represses the pro-duction of pathogen metabolites inhibitory to bac-terial antibiotic biosynthesis. and its mechanisms for coleus root rot management. Together, these genes provide a view of the rhizosphere environment as perceived by a rhizosphere colonist, and suggest that the nature of the association between P. fluorescens and the plant root may be more complex and intimate than previously thought. Having these bacteria in a root system may help plants resist fungal infections and can help plants absorb nutrients more effectively. Rainey PB(1).

Tolerance level was found high in Pseudomonas fluorescens against Spinosad @ 0.04 % (9.02 × 108 cfu/ml) and Imidacloprid @ 0.02 % (5.82 × 108 cfu/ml). Adaptation of Pseudomonas fluorescens to the plant rhizosphere. The multiplication rate of nematodes and number of root-galls were less in the presence of Pseudomonas fluorescens as compared to its absence. It grows best in temperatures that are 25-30℃. Bio-control of Paddy-Blast and sheath blight. Pseudomonas fluorescens is an obligate aerobe, gram negative bacillus.These bacteria are able to inhabit many environments, including: plants, soil, and water surfaces. Soil bacteria such as pseudomonads may reduce pathogen pressure for plants, both by activating plant defence mechanisms and by inhibiting pathogens directly due to the production of antibiotics. KAU Mannuthy shows the methods for applying these for better crops. Its name comes from its production of the soluble fluorescent pigment pyoverdin. Pseudomonas fluorescens are gram-negative bacilli shaped bacteria. Global emergence of Pseudomonas fluorescens (P. fluorescens) displays a mechanism of resistance to all existing antimicrobials. against pathogens with different lifestyles are not y … Pseudomonas species have been widely studied as biological agents (BCAs) and it is alternative to the application of chemical fungicides.
