Abstract

In this study one hundred twenty PSEUDOMONAS FLUORESCENS isolates were collected by use of King's B medium from field soils of different regions Khuzestan province including: Dezfu1,Shoshtar, Shosh, Mollasani and Sosangerd. Only three isolates had suitable ANTAGONISTic and biological effects on Rhizoctonia solani, the casual agent of been seedling damping off in laboratory experiments. These strains were identified by current methods in bacteriology and belonged to Pseudomons fluorescens. Each strain showed significant effect on dead plant percent reduction in compare with check. But effect of strain 24 was more than the others. These bacterial strains produced a kind of metabolite on PDA (containing 5% glucose) that could inhibit the growth of casual agent of seed rots and seeding damping off in the absence of bacteria. This metabolite seems to be art ANTIBIOTIC. Anyone of strain did not produce SIDEROPHOR on PDA (containing 5% glucose) amended with different concentration of FeCl3.
