Occurrence of Erysiphe friesii var. dahurica on purple buckthorn (Rhamnus purpurea) from Pakistan

Abstract Leaves of purple buckthorn observed with powdery mildew symptoms were collected from the district Abbottabad, Khyber-Pakhtunkhwa, Pakistan during field tours from August to October between 2017 and 2021. Morpho-anatomical features and molecular phylogenetic analysis were used to identify the causal agent as Erysiphe friesii var. dahurica. Pathogenicity was confirmed on healthy leaves of Rhamnus purpurea in a glasshouse at 25°C with 75 to 80% humidity and after inoculation, white powdery colonies appeared after 7 to 10 days. The fungal colonies were checked for the confirmation of pathogen. Erysiphe friesii var. dahurica on R. purpurea is being described here as a new record for Pakistan and Rhamnus purpurea is a new host, reported for the first time.

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 Disease reports are brief, previously unpublished accounts of diseases occurring on a new host or geographic region.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.
