The tea root lesion nematode, Pratylenchus loosi, has been shown internationally serious nematode pest causing yield losses in tea plantations. The purpose of this study is that, with regard to biological control as one of the main section nematodes and sustainable agriculture, integrated management systems, allowing application and Pseudomonas fluorescens in the rhizosphere of tea root lesion nematode control to check. To evaluate these potentiality more than forty bacterial strains were collected from rhizosphere of tea plants and screened for their antagonistic activities towards adult and juvenile Pratylenchus loosi for population density reduction under in vitro condition. Eight selected isolates with nematicidal activity were characterized and identified. All belonged to the genus Pseudomonas. Seven strains were identified as Pseudomonas fluorescens and one as P. aeruginosa. Death percentage of juveniles ranged from 63.10% to 95.24% for P. fluorescens (Rh-36) and P. fluorescens (Rh-19), respectively.
