The effects of postharvest application of surface sterilizing agents on the incidence of fungal rots in stored apples and pears.

These investigations were conducted over 2 years using fruits of apple cultivars Cox's Orange Pippin and Bramley's Seedling, and pear cv. Doyenne du Comice. The effects of treatments on Cox apples stored in controlled atmospheres (CA) differed according to the source of the fruits. Chlorine (as calcium hypochlorite) reduced rotting in fruits from one orchard, but increased rotting in fruits from another orchard. In the same experiments, drenching with metalaxyl + carbendazim reduced rotting, despite the presence of carbendazim-tolerant strains of Botrytis cinerea. A peroxide-based sterilant gave similar results on Cox to those obtained with chlorine. Chlorine treatment reduced rotting of air-stored Bramley apples by 59%, reduced rotting of Comice pears by 51%, and was as effective as metalaxyl + carbendazim and iprodione, respectively, in controlling storage rots. It is suggested that chlorine treatment could be an alternative to postharvest fungicide application. Addition of a non-ionic surfact

ant did not improve the efficacy of chlorine, and the effectiveness of metalaxyl + carbendazim treatment was not increased by drenching in chlorine prior to fungicide application.
