Abstract
Sterilization is an important factor in reprocessing of drained nutrient solution (RDN). To evaluate the suitability of ozone microbubble for RDN in protected horticulture and plant factory, strong fungicidal activity of ozone and microbubble were applied. This experiment was taken advantage of ozonated water (OW) and ozone gas (OG). The Fusarium oxysporum (FO), Phytophthora capsici (PC) and Colletotrichum gloeosporioides (CG) were treated with OW 0.5, 1.0 and 2.0 ppm and OG $3.0g{\cdot}h^{-1}$ for 0, 30, 60, 120 and 180 sec. Results of this experiment can be summed up as follows : In the OW, FO was sterilized by 0.5 ppm in 60 sec and PC was sterilized by 2.0 ppm in 30 sec. In the OG, FO and PC both of them were sterilized in 180 sec. However, CG was not sterilized using OW and OG. Overall, ozone microbubble showed possibility of sterilization in RDN. However, CG is required to more ozone concentration and processing time.
