Field investigation on symptom and occurrence characters of Chinese yam anthracnose was carried out in 2014-2016 at main producing area of Dehua and Anxi County, Quanzhou City. The occurrence characters of Chinese yam anthracnose showed as follows:high temperature and humid were the chief environmental conditions; very different disease-resistant capacities were found among major cultivars and high incidence rate occurred in continuous cropping fields. Based on these occurrence characters and local climate and cultivation conditions, some comprehensive control measures were proposed.
