3.5. In vivo antifungal assay of ozone against C. gloeosporioides
As shown in Fig. 5, there was a significant (p < 0.05) delay in
anthracnose disease development in artificially inoculated papaya
fruit, after 96 h of ozone exposure during the 14 days of ambient
storage (25 ◦C, 70% RH). The disease incidence and severity in the
controls increased gradually from day to day and reached 100%
(scale 3.8), after 10 days of storage (Fig. 5). The symptoms were
visible as early as 2 days of storage and most papayas were spoiled
due to severe disease infection. Different concentrations of ozone
