摘　　要：荔枝麻点病,俗称“鸭头绿”,其病原菌为暹罗刺盘孢Colletotrichum siamense,其典型症状为产生黑褐色麻点状小斑点,病斑周围常形成绿色斑,是炭疽病的一种症状类型。然而,生产中也存在一些与麻点病相似的症状,加之文献少有相关记述,常被误认为是麻点病。为明确这些易混淆症状与荔枝麻点病的区别,经多年的田间观察,发现这些易混淆症状多是生理性病害或虫害引起。本文就荔枝麻点病及其易混淆症状进行了汇总,记述了各自的症状、成因及其防治方法,并提供了相应的症状照片,为荔枝麻点病及这些易混淆症状的正确识别和精准防控提供了参考。Litchi pepper spot disease,commonly known as yatoulü(meaning‘greenness in duck head’),caused by Colletotrichum siamense,with typical symptoms of black spots and sometimes green patches formed around them,is a type of litchi anthracnose.However,there exist some symptoms similar to litchi pepper spot disease in the field,which were rarely mentioned in the literatures and frequently mistaken for litchi pepper spot disease.In order to differentiate litchi pepper spot disease from the easily confused symptoms of litchi fruits,we conducted field observation for years,and found that most of these easily confused symptoms were resulted from physiological diseases or insect attacks.Here,litchi pepper spot disease and the easily confused symptoms were summarized,with the descriptions of their symptoms,causes and prevention methods.The photographs of the symptoms were also provided.Therefore,it would be beneficial to accurate identification and field control of litchi pepper spot disease and the easily confused symptoms.
