摘　　要：胡萝卜（Daucuscarota）又名黄萝卜、丁香萝卜，是伞形花科萝卜属的一、二年生草本植物，原产亚洲西南部，约在13世纪从伊朗引人中国，主要用作鲜冷冻蔬菜产品出口，我国现已成为世界胡萝卜第一生产国和主要出口国。2012年云南省昆明市农贸市场发现一种采后胡萝卜新病害。In October 2012, infected post harvest carrot root were found with decay symptom in several farmer markets around Kunming city of Yunnan Province, China.

According pathogenicity, morphology and sequence of the rDNA internal transcribed spacer region （ ITSI-5.8S-ITS2 ）, the pathogen was identified as Ceratocystisfimbriata. The disease has been reported only in Brazil before, this is the first report on C. fimbriata as the pathogen of carrot（Daucus carota） decay post harvest in China.
