The twig blight symptoms were observed in Chinese magnolia vine (Schisandra chinensis) at Mungyeong city, Gyeongbuk province, Korea in June 2015. The typical symptoms of infected plant were shriveled and wilted in leaves which led to blight resulted in death. Based on the morphological characteristics, the isolate was suspected as Botryosphaeria sp. Inoculation of isolated pathogen was performed to identify its pathogenicity according to Koch`s postulates. Re-isolated fungi from the inoculated stem was showed same morphological characteristics with original pathogen. Phylogenetic analysis was performed using combined sequence of rDNA internal transcribed spacer region, EF1- and -tubulin gene. The isolated pathogen was identified to the B. dothidea by phylogenetic analysis. This is the first report of twig blight on S. chinensis caused by B. dothidea in Korea.
