Popis:	Fludioxonil, a reduced-risk fungicide, was evaluated for the control of postharvest gray mould (caused by Botrytis cinerea) and blue mould (caused by Penicillium expansum) in pears in cold and controlled atmosphere (CA) storages. Lower blue mould incidence was observed in pears stored at 0°C as compared to pears stored at 4°C for up to 60 days, while lowest gray mould incidence was observed in both storages. In a time-course study, two of the highest concentrations tested, 300 and 600 µg mL−1, suppressed gray mould and blue mould for up to 100 days at 0°C and an increase in disease incidence was observed in the subsequent shelf-life studies. Both drench and dip application methods of fludioxonil at a concentration of 600 µg mL−1 provided effective control of gray mould and blue mould in CA storage for 4.5 months. Fludioxonil has the potential to be incorporated into the thiabendazole resistance management strategies for the control of postharvest diseases of pears.
