Occurrence of Passalora Leaf Spot Caused by P assalora ampelopsidis on Virginia Creeper in Korea

Abstract A previously unknown leaf spot disease was observed on Virginia creeper ( Parthenocissus quinquefolia ) vines in Seoul, Korea. Affected plants exhibited leaf spots and discoloration, resulting in leaf blight and premature defoliation. The causal agent of the disease was identified as Passal...

Summary:Abstract A previously unknown leaf spot disease was observed on Virginia creeper ( Parthenocissus quinquefolia ) vines in Seoul, Korea. Affected plants exhibited leaf spots and discoloration, resulting in leaf blight and premature defoliation. The causal agent of the disease was identified as Passalora ampelopsidis by comparing morphological characteristics and analyzing the internal transcribed spacer region of the rDNA . Pathogenicity tests were conducted twice with the same results, fulfilling Koch's postulates. Passalora leaf spot on Virginia creeper vines was first recorded in the United States in 1878. Recent reports of Passalora leaf spots on Virginia creeper vines in 2005 in Germany, in 2012 in China and now in Korea indicate the prevalence of the disease.
