Abstract/SummaryThree concentrations of Xenorhabdus nematophila and Xenorhabdus spp., (4x10(5,) 4x10(6,) 4x10(7) cells/ml) were evaluated in the laboratory and in pot experiments to test their antagonistic effects on Fusarium oxysporum f.sp., lycopersici. All concentrations effectively inhibited its growth on agar plates. In soil under greenhouse conditions treatments with each bacterium at 4x10(7) cells/ml reduced the disease incidence of tomato by up to 40.38 and 47.54% respectively and there were significant increases of plant biomass by 198 and 211% respectively. The rhizosphere population of Fusarium oxysporum f.sp., lycopersici was reduced by 97%. The Xenorhabdus spp., was comparatively more effective than X. nematophila.
