Asian pears are also called Oriental pears, Chinese pears, Japanese pears, Salad pears and Apple pears. The cultivated varieties of Chinese and Japanese pears were developed from Pyrus ussuriensis Maximowicz, P. Serotina Rehder (P. pyrifolia [Burman] Nakai) and possibly other native species.
Since definite causes have not been identified; there is no effective way to control Flesh Spot Decay. The inability to predict or diagnose Flesh Spot Decay without cutting the fruit makes it difficult to study the problem. Further research needs to be carried out to determine the causes and variety susceptibility, and to understand preharvest and/or postharvest practices that will reduce Flesh Spot Decay losses. Meanwhile, AVOID whenever possible the following conditions that might induce Flesh Spot Decay: low crop load and therefore large fruit; advanced maturity; sunburn; erratic irrigation (amount and timing) near harvest; harvesting fruit during warm temperatures and cooling the fruit within 24 hours.
