Control of Botrytis cinerea rot in stored kiwifruit by physical and chemical systems.

New methods for curing and controlled atmosphere storage (delay in gas intake and low level of CO2) were tested on kiwifruits to reduce the incidence of B. cinerea rot, simultaneously testing the efficacy of several fungicides applied to fruits after harvest. Curing reduced significantly the rate of B. cinerea rot. The best results were obtained with curing-programmed temperature reduction down to 1 deg C in 8 days. It was confirmed that rate of rot may be reduced by delaying the start of the controlled atmosphere conditions 30-35 days after harvesting. The incidence of B. cinerea was further reduced by lowering the level of CO2 from 4.5 to 1.5%. Fenhexamid, fludioxonil + cyprodinil and trifloxystrobin were more effective than the commercially available fungicide (vinclozolin), when applied to fruits by dipping. The integration of natural (delaying of refrigeration-curing) and chemical methods (postharvest application of vinclozolin or fenhexamid) reduced the incidence of B. cinerea rot to nearly negligible levels.
