摘　　要：近年来,随着槟榔种植面积迅速扩大,由槟榔黄化病等引起的“黄化灾害”问题日趋严重,造成广大种植户丧失信心,严重制约了槟榔产业的可持续发展。为了准确甄别不同病害,于2018—2020年在万宁、琼海、文昌等市县进行了系统调查,共发现槟榔病害16种,将其中7种病害(黄化病、隐症病毒病、炭疽病、坏死环斑病毒病、坏死梭斑病毒病、细菌性叶斑病、根腐病)评价为致黄关键病害,分析了每种病害的病原菌、发生频率、分布范围、为害特征及防控难度。In recent years with the expansion of planting area of areca palm, ‘yellowing disaster’ caused by yellowing diseases such as areca palm yellow leaf disease turns to be more serious, which has made the growers lose their confidence in planting areca palm continuously and significantly restricted the development of areca palm industry. A systematical survey was carried out in Wanning, Qionghai and Wenchang from 2018 to 2020 in order to identify the difference of the diseases. A total of 16 areca palm diseases were observed, of which 7 diseases (yellow leaf disease, leaf yellowing virus disease, anthracnose disease, necrotic spindle-spot virus disease, necrotic ringspot virus disease, bacterial leaf spot disease and root rot disease)were identified as key leaf yellowing-related diseases. These diseases were analyzed in terms of causal agent, occurrence frequency, distribution, infection characteristics and key control and prevention difficulties.
