由贝伦格葡萄座腔菌（Ｂｏｔｒｙｏｓｐｈａｅｒｉａｂｅｒｅｎｇｅｒｉａｎａｄｅ．Ｎｏｔ．）和贝伦格葡萄座腔菌梨生专化型〔Ｂ．ｂｅｒｅｎｇｅｒｉａｎａｄｅ．Ｎｏｔ．ｆ．ｓｐ．ｐｉｒｉｃｏｌａ（Ｎｏｓｅ）Ｋｏｇａｎｅｃａｗａｅｔ．Ｓｏｋｕｗａ〕所致的果实腐烂病可以统称为果实轮纹病。前者俗称干腐病菌，后者俗称轮纹病菌。在果园所出现的病果中，两菌的比例有较大变化，但多以前者为主。果实轮纹病菌主要来源于枝干病斑和果园内外的各种枯死枝，清除病菌对该病的防治有重要作用。目前控制为害的主要措施是适时喷洒杀菌药剂。从落花后１０ｄ左右开始，到７月底或８月上、中旬结束是主要的用药时期。这段时间内，坚持“雨后喷药”是防治成功的关键。

In the orchard of the disease, the proportion of two bacteria have a greater change, but mostly the former. Fruit rotten bacteria mainly stems from branches and spotted orchards inside and outside the various dead branches, removal of germs on the prevention and treatment of the disease have an important role. The main control measures are currently spraying the timely sterilization agent. From about 10 days after falling to the beginning of July or August, the end of the middle is the main period of medication. During this period of time, sticking to the “spray after the rain” is the key to the success of prevention and treatment.
