Antifungal action of ozone against Colletotrichum gloeosporioides and control of papaya anthracnose Mei Kying Ong a , b , c , Asgar Ali a , Abstract To elucidate the antifungal action and possible responses of ozone on the fungus, the effect of gaseous ozone on the germination of conidia of Colletotrichum gloeosporioides , anthracnose control in papaya and mitochondrial degradation in spores was studied. Ozone treatment appeared to suppress the growth of C. gloeosporioides in the in vivo study. Ozone also induced the generation of reactive oxygen species (ROS) in the fungal spores as shown by the oxidant-sensitive stain 2,7-dichlorodihydrofluorescein diacetate. Degradation of mitochondria in the spores was observed after 24 h of ozone treatment at 3.5 and 5.0 μL/L using transmission electron microscopy. Abnormalities in the ultrastructure of spores treated with 5.0 μL/L ozone included an increase i...
