Abstract
Rumex obtusifolius, a perennial plant native to Europe, has become an aggressive invasive weed across temperate regions worldwide. Rumex obtusifolius poses a significant threat to agricultural ecosystems, highlighting the need for effective management strategies. During the summer of 2022, powdery mildew-like symptoms were observed on the leaves of R. obtusifolius at four locations in Korea. The causal agent was identified as Teratoramularia rumicicola through morphological characterization and phylogenetic analysis based on the ITS and LSU genes of the rDNA. Artificial inoculation of healthy R. obtusifolius leaves with an isolate obtained from this pathogen led to symptom development after 6 days, thereby fulfilling Koch's postulates. This study is the first global report of R. obtusifolius infected with T. rumicicola.
期刊介绍：
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
