In the field of plant pathology, exploitation of metal nanoparticles in bacterial disease management is a novel and needy approach. Green synthesis of nanoparticles is most prioritized because of their safe, eco-friendly nature and cost effectiveness. A total of 16 fluorescent pseudomonad isolates were obtained from different crop rhizosphere in various locations. | Green synthesis of zinc nanoparticles using pseudomonas fluorescens extract and their antibacterial activity against Xanthomonas spp.
