An analysis of postharvest crop loss in Victorian pome fruit.

Apple and pear losses in Victoria, Australia were estimated for the 1988-89 season by recording pack-out rates and by sampling for defects at representative packing houses during the storage season following the 1988 harvest. For the 6 main cultivars (Golden Delicious, Granny Smith, Jonathan and Red Delicious apples, and Beurre Bosc and Packham's Triumph pears), total losses at the point of removal from cold storage were estimated as $A 8.9 million (22% of the total post-storage crop value). Pre-harvest injury was the main cause of downgrading followed by miscellaneous defects arising from pre-harvest, harvest and postharvest mechanical damage, and insect injury. Fungal diseases and insect damage were the main causes of wastage. Pre-harvest defects contributed directly to postharvest loss because of the storage and handling costs incurred, and indirectly by pre-disposing fruits to postharvest decays. Rejection rates were related to cultivar, orchard, district and handling methods, and increased

marginally with storage duration.
