总结
苹果疫霉（Phytophthora japoniae（Kleb.）克莱伯果腐病表现为坚硬的褐腐病，这种褐腐病在果实中蔓延，随后可能被二次腐烂的生物所掩盖。在1973-77年的四个果实贮藏季节中，肯特和苏塞克斯的商业苹果作物中的病害发生变化很大。在果园中最初感染后，疾病在冷藏期间传播到邻近的健康水果。在实验室或商业作物中，收获后用苯菌灵水溶液处理对水果中疾病的传播或发展没有一致的影响。有人建议，土壤污染的水果和雨水飞溅从土壤中感染的果园，最近流行的疾病可能是一个结果，果园裸露土壤的维护和矮化砧木和修剪系统的使用增加，使水果生长更接近地面。
SUMMARY
Apples affected by Phytophthora syringae (Kleb.) Kleb. fruit rot show a firm brown rot which spreads through the fruit and may later be masked by secondary rotting organisms. Occurrence of the disease in commercial apple crops in Kent and Sussex was extremely variable during the four fruit storage seasons 1973–77. Following initial infection in the orchard, the disease spread to adjacent healthy fruit during refrigerated storage. Post-harvest treatment with benomyl in water had no consistent effect on the spread or development of the disease in fruit in the laboratory or in commercial crops. It is suggested that soil contamination of fruit and rain splash from soil are the means of infection in the orchard, and that the recent prevalence of the disease may be a result of the maintenance of bare soil in orchards and the increased use of dwarfing rootstocks and pruning systems so that fruit are grown nearer to the ground.
