摘要
近年来,柑橘黑点病(Diaporthe citri)在浙江、江西等柑橘产区普遍发生,逐渐成为柑橘最主要病害之一,严重影响鲜销果实的外观品质和销售价格。2008年以来,通过对该病的症状、发生规律和防治技术开展研究发现,果实整个生长期都能感病,但以果实膨大期最感病;黑点病的严重度与树龄、施肥水平和杀菌剂的使用次数关系密切;以座果后每隔20 d使用保护性杀菌剂代森锰锌防治效果较好,代森锰锌中添加0.25%～0.50%矿物油(绿颖)能有效地提高其防效。文章同时结合国内外相关研究,对黑点病症状、病原、发生规律和防治技术作了较为详尽的综述。
Melanose, caused by Diaporthe citri, has become a serious disease on citrus fruits in citrus-growing region of Zhejiang, Jiangxi provinces etc. It deteriorates exterior quality and brings down sale price of citrus fruits for fresh marketing. We have been involved in the investigation of the symptoms, prevalence and control methods of this dis- ease since 2008. It was demonstrated that citrus fruits are susceptible to this disease in whole developmental stage, and especially susceptible during the enlarging stage. The order of melanose severity was closely associated with cit- rus age, times of fertilization and fungicide application. The best control efficiency could be obtained by application of protective fungicides such as mancozeb （followed the instruction of manufactory） 20 days interval after fruit-set- ting. Superior efficiency would be even achieved when 0. 25% to 0. 5% mineral oil （SK spray oil） was mixed with mancozeb. Inter- and intranational information regarding the symptoms, characteristics of pathogen, epidemic factors and disease control of melanose was elaborately integrated in this paper.
