Impact of Pseudomonas fluorescens on Field Pathogen: A Commercial Biofungicide Study

To evaluate the efficacy of Ami Sudo Star, comprising Pseudomonas fluorescens, as a biocontrol agent for inhibiting mycelial growth of Fusarium oxysporum in Solanum lycopersicum L. Pseudomonas fluorescens was evaluated in vitro against Fusarium oxysporum using dual culture and agar well diffusion techniques.Then, using a dose of 1 kg per acre in the field, characteristics including the vigour index, shoot length, root length, and germination percentage were assessed.Pseudomonas fluorescens showed zones of inhibition against Fusarium oxysporum in both the dual culture and agar well diffusion techniques, measuring 36.3 ± 4 mm and 39.1 ± 2 mm, respectively, according to the results.Moreover, the treatment of Ami Sudo Star greatly enhanced seedling growth and facilitated plant development as compared to untreated plants.The current study introduced the utilization of Ami Sudo Star in powder formulation, which led to a substantial reduction in the prevalence of Fusarium oxysporum as well as noteworthy enhancements in seedling growth and other indicators of plant development.
