Pseudomonas fluorescens is an aerobic, gram-negative, ubiquitous bacterium present in agricultural soils that is well adapted to grow in the rhizospheric as well as phyllospheric zone. An experiment was conducted at Shree Agrasen Kanya P.G. College, Varanasi, U.P. India aimed to determine the morphological features of P. fluorescens as well as to carry out the process and method of its commercial production of powder formulation of the bio-control agent P. fluorescens 1 % W.P for its effective use at field. Its morphology is characterized visually and microscopically by colony growth such as colony form, color, edge and Gram staining at laboratory. The quality parameters of P. fluorescens were checked for pH, moisture content, cfu, suspensibility and antagonistic capability. In this paper the detail protocol have been mentioned for preparation of talc base powder formulation of P. fluorescens and how to check various quality parameters. P. fluorescens was found most effective with highest antagonistic activity against six chosen fungal pathogen that showed maximum inhibition of mycelia growth of Fusarium oxysporum (62.60 %), Aspergillus niger (55.47 %), Rhizoctonia solani (53.8 %), Macrophomina phaseolina (52.30%), Alternaria alternata (49.58 %) and Pyricularia oryzae (47.67%).
