Abstract

Abstract Plants of Cotinus coggygria were observed with powdery mildew symptoms during field surveys in Abbottabad, Khyber Pakhtunkhwa (KP), Pakistan in 2020. Morpho-anatomical and molecular phylogenetic analyses were used to identify the powdery mildew species parasitizing these plants as Erysiphe verniciferae. Pathogenicity was confirmed on healthy leaves of C. coggygria in a greenhouse at 25°C with 75–80% humidity at 7–10 days after inoculation, when white powdery mildew colonies appeared. This is the first report of powdery mildew caused by E. verniciferae on C. coggygria in Pakistan.

白丹毒引起巴基斯坦黄檗白粉菌的初报

摘要2020年，在巴基斯坦开伯尔-普赫图赫瓦省阿伯塔巴德市的实地调查中，观察到黄檗属植物出现白粉病症状。通过形态解剖和分子系统发育分析，鉴定了寄生在这些植物上的白粉菌属。在接种后7-10天，在温度为25°C、湿度为75–80%的温室中，当出现白色白粉菌菌落时，黄曲霉的健康叶片被证实具有致病性。这是巴基斯坦首次报道由E.verniciferae引起的黄颡菌白粉菌。

期刊介绍： Canadian Journal of Plant Pathology is an international journal which publishes the results of scientific research and other information relevant to the discipline of plant pathology as review papers, research articles, notes and disease reports. Papers may be submitted in English or French and are subject to peer review. Research articles and notes include original research that contributes to the science of plant pathology or to the practice of plant pathology, including the diagnosis, estimation, prevention, and control of plant diseases. Notes are generally shorter in length and include more concise research results. Disease reports are brief, previously unpublished accounts of diseases occurring on a new host or geographic region. Review papers include mini-reviews, descriptions of emerging technologies, and full reviews on a topic of interest to readers, including symposium papers. These papers will be highlighted in each issue of the journal and require prior discussion with the Editor-in-Chief prior to submission.
