摘　　要：沃柑是“坦普尔”橘橙(Citrus tangerina×C.sinensis)与“丹西”红橘(C.tangerina)杂交种,属晚熟杂交柑橘。由于其生长势强,结果早,产量高,果形好,色泽鲜艳,品质优而深受市场欢迎。沃柑自2004年引入我国,之后沃柑产业在我国迅速发展,目前仅广西的种植面积就超过13万公顷[1]。A cosmetic defect on fruits of citrus Orah((Citrus tangerina×C.sinensis)×C.tangerina)and Shatangju(Citrus reticulata Blanco cv.Shatangju)outbreaks in Southern China recently.As necrosis of outer layer cells in the green pericarp of fruits,the symptoms looked like ringworm or tinea,the name of“white scaled blotch”was given.However,as the etiology of the disease has not been determined,the strategy for prevention and control of this disease was confusion.In this study,field investigation was token and samples were collected from more than 10 orchards in the Guangxi and Guangdong provinces during 2020 to 2022.The pathogen was isolated on the infected pericarp,and its pathogenicity was confirmed with Koch’s postulates.Based on morphology and phylogenetic analysis of thecombined sequence data of LSU,ITS and rpb2,the pathogen was identified as Zasmidium fructicola.The determination of etiology lays a foundation for the study of epidemiology and to guide prevention and control of this disease.
