Survey and control of the occurrence of mycotoxins from postharvest vegetables in Korea. III. Control of mycotoxin producing pathogens in postharvest vegetables (garlic, onion and pepper).

The pathogenicity of mycotoxin producing fungi, the effect of temperature on infection by these fungi, and the control of postharvest disease by antifungal agents were investigated in the Korea Republic. Vegetables were not infected by mycotoxin-producing fungi when there was no wound, but were infected by wound inoculation. Even though the fungi did not infect the vegetables at low (4 deg C) and high temperatures (38 deg ), the quality of the vegetables was lowered by high temperature. Chitosan and GFSE (grape fruit seed extract) greatly inhibited mycelial growth and spore germination of Alternaria spp. and Penicillium spp., whereas sodium hypochlorite did not. Chitosan inhibited Fusarium species, whereas GFSE and sodium hypochlorite did not. Both Alternaria spp. and Penicillium spp. were not controlled by chitosan but controlled by GFSE and sodium hypochlorite. GFSE was not effective in the control of Fusarium sp. but chitosan and sodium hypochlorite were effective.
