Pseudomonas fluorescens was used as a biological control agent against bacterial wilt disease caused by Ralstonia solanacearum. Activities of phenylalanine ammonia lyase (PAL), guaiacol peroxidase (POX), polyphenol oxidase (PPO) and lipoxygenase (LOX) increased in P. fluorescens pretreated tomato seedlings, which were later inoculated with R. solanacearum and activities of PAL, POX, PPO and LOX reached maximum at 12, 9, 15 and 9 h, respectively, after inoculation.
