摘要
近年来,山东省烟台市套袋苹果上出现1种新的病害,典型症状为圆形的痣状疮痂斑,经病原菌的分离鉴定,初步确定由Venturia asperata侵染所致,中文可用"苹果痣状疮痂病"表述。根据国外的报道分析,苹果痣状疮痂病的病原菌主要在落叶上越冬,苹果开花后产生子囊孢子,于降雨期间随气流传播侵染幼果和叶片,受侵染的叶片产生分生孢子再侵染,但没有明显的症状。多雨的年份幼果期发病严重。清除病落叶,幼果期随其他病害的防控,于降雨前后喷2~3次杀菌剂,可有效控制其危害。
In recent years, a new disease appeared on apple bagging fruits in Yantai producing area. The typical symptom is round mole-shaped scabs. After the isolation and identification of pathogen, it was confirmed to be atypical scab-like symptoms and caused by Venturia asperata. The Chinese name of the disease can be expressed as“ping-guo-zhi-zhuang-chuang-jia-bing”. According to foreign reports, the pathogen of the disease mainly overwinters on fallen leaves, produced ascospores after flowering, and spread with airflow during rainfall to infect the young fruits and leaves of apple. The infected leaves can produce conidia for re-infection, but there are no obvious symptoms. The disease is serious in rainy years of the young apple fruit growing period. Removing fallen leaves, and applying fungicide before and after rainfall for 2~3 times can effectively control the disease.
