Reducing the reliance on post-harvest fungicides to control storage rots of apples and pears.

The uncertain future of postharvest fungicide treatments has created the need to find alternative control methods for reducing storage rots in apples and pears. Foliar application of captan (2.7 kg/ha) to Cox's Orange Pippin (Cox) tres in late-July, mid-August and early September reduced post harvest losses due to Phytophthora syringae, Nectria galligena and Monilinia fructigena. Chlorine drenching, with or without the addition of a non-ionic wetter, was as effective as iprodione in reducing the incidence of Botrytis rots in Doyenne du Comice pears. Postharvest application of Aspire (3 g/litre), a wettable granule preparation of Candida oleophila, either alone, or in combination with a low dose of carbendazim (50 mg/litre), reduced Botrytis rots in Cox apples stored in bulk bins. However, in a small-scale trial, C. oleophila failed to reduce the incidence of rotting in Cox apples and Conference pears inoculated artificially with a spore suspension of either B. cinerea or Penicillium expansum. Ap

plication of Cryptococcus laurentii reduced the incidence of Botrytis and Penicillium rots in artificially inoculated Cox apple and Conference pear fruits.
