Present study aimed to determine the effects of fludioxonil (FLU) against the gray mould disease development on pomegranate fruits; and the residue levels of FLU during 150 days of storage. Pomegranate (Punica granatum) fruits are very susceptible to postharvest decay (Botrytis cinerea Pers.) and very few chemicals are approved for the use in postharvest storage. Studies conducted with ‘Wonderful’ cultivar pomegranate fruits at 6±1°C and 90-95% relative humidity under cold storage conditions. Results suggested that FLU can protect fruits up to 60 days without facing any gray mould problem. Results also showed that, the FLU deposits on pomegranate fruits reduced far below to the maximum residue limit (MRL) of European Union: 3 ppm within 7 days after the treatment, but continue to protect the fruits by preventing conidial germination of fungus.
Key words: Storage, Botrytis cinerea, fungicide, maximum residue limit.
