• Twenty-one strains of fluorescent pigment-producing Pseudomonas (abbreviated to FPP-Pseudomonas) species were isolated from soil and roots of apple and peach trees using selective media. FPP-Pseudomonas strains were identified as Pseudomonas fluorescens. Moreover, on the basis of the utilization of several organic compounds, these strains were divided into three groups. P.fluorescens strains isolated from the roots were assigned to mainly groups 1 and 2, and most of the isolates from the soil to group 3. All the strains of group 2 exhibited antifungal activity (in vitro) against three soilborne plant pathogenic fungi : Rhizoctonia solani, Verticillium dahliae, and Rosellinia necatrix. These results suggest that the strains of group 2 play an important role as antifungal rhizobacteria.
