| Abstract: | A leaf spot disease on Chenopodium quinoa was found in Jingle, Shanxi. The leaf spots appeared as yellow nearly-circular spot on the surface at early stages, and gradually formed large lesions with pale brown mold at late stage. Based on analysis of LSU, rpb2 and ITS sequences, the strains used in this study were located in same cluster with Cercospora cf. chenopodii in phylogenetic tree. According to morphological characteristics, pathogenicity test, and molecular identification, the pathogen causing leaf spot on quinoa was identified as Cercospora cf. chenopodii. |
