Investigations on Disinfection Possibilities with Ozone in Indoor at The Simulation of Seedling Nursery Facilities

In agricultural production, it has become a main topic in recent years to obtain healthy crops in accordance with environmental friendly production techniques. The most important prerequisite for agricultural production is the provide of healthy plant production material in process. Ozone is a very strong disinfectant with its high oxidation ability. With this feature, it is used as general disinfectant in many sectors and for different purposes. In this study, the possibilities of using ozone for the general disinfection of indoor environments of plant nursery facilities which are provide material to open field and greenhouses were investigated. The research has been carried out by applying high-dose ozone in gas forming for a short time in Indoor with intensive microbiological load. The treatment at 100-150 mg O3/Nm3 and one hour has completely eradicated the microbiological loads present. The microbiological loads on the cabin atmosphere and surfaces was also controlled by applying ozone doses of 75 and 85 mg O3 / Nm3 for 1 hour. There was a strong negative correlation between increased ozone dose and microbiological load. A similar effect was also determined on the disinfection process of artificially inoculated with Fusarium oxysporum f. sp. lycopersici propagules
