Abstract:

The potential of ozonated water was investigated as an alternative to soil disinfectants in reducing the population densities of Fusarium oxysporum f. sp. lycopersici in artificially infested quartz sand and Kuroboku soil columns. Significant reductions in the population density were observed with dissolved ozone concentrations (DOCs) of 6 and 12 mg L −1 in infested quartz sand but not in infested Kuroboku soil. The results indicate that repetitive application of ozonated water with higher DOCs should be required for reducing the population density of F. oxysporum in soils with high content of organic substances and large surface area.
