Inactivation of Fusarium oxysporum Conidia in Soil with Gaseous Ozone - Preliminary Studies

摘要

In this study, the efficiency of gaseous ozone (O-3) injected in the soil as an oxidizing agent for the inactivation of F. oxysporum was evaluated under laboratory conditions. The results show the treatment reached an inactivation efficiency of 76% after an applied dose of 0.40 g O-3 kg(-1) soil. This shows that the injection of O-3 can be a viable alternative to control pathogenic organisms in the soils. Nevertheless, it is clear that more studies on determining the effects of this treatment on soil quality are needed.
