摘要
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。
The fruit rot diseases which were induced by Botryosphaeria berengeriana de.Not. and B.berengeriana de.Not.f.sp.piricola (Nose)Koganecawa et.Sokuwa were called fruit Ring rot.The former fungi usually was called Dry rot fungi and the latter one was called Ring rot fungi.There is a clear change of the ratio of these two kinds of fungi in different orchards,but the important one is Botryosphaeria berengeriana. The pathogen fungi of fruit Ring rot come from diseased branches and all kinds of dead branches.Therefore,we can control this kind of diseases by cleaning diseased and dead branches in orchards.At present,the key measure of controlling this kind of desease is to spray fungicide upon the trees at optimum time.From 10 days after dropping of blossoms to the end of July or the 15th of August,this period is key time of spray.The key point of controlling the diseases is spraying fungicide after rain.
