Abstract

For the selection of powerful antagonistic bacterium for biological control of Ewinia sp. causing vegetable soft rot, two excellent strains (54, 565) were selected from 1, 196 strains of bacteria which were isolated from rhizospere in vegetable root rot suppressive soil. Selected 2 strains were identified to be a species to Pseudomonas fluorescens S4 and pseudomonas fluorescens S65 (PS65). The highest of inhibitory activity was produced in 523 synthetic broth medium at pH 7.0 and 25t during 3 ethyl-Al-folpet, and the antibiotics such as vancomycin, perucillin and lincomycin, only PS4 was resistant to erythromycin.
