Control of postharvest diseases in longan fruit by ozone
In order to study the effects of ozone gas treatment on postharvest diseases of longan fruits, cultures of the fungi Lasiodiplodia sp. and Cladosporium sp. cultured on potato dextrose agar (PDA) were exposed to 20 ppm of ozone. The ozone was applied directly on mycelia of Lasiodiplodia sp. or spore...
