Abstract
In September of 2019, root and stem rots were observed in tobacco plants in Xingren, Guizhou Province, China. Typical symptoms included rotted roots and stems, failure to form vascular bundles or complete necrosis of vascular bundle tissues, and the plant later showed hollow stems and complete wilt. In a 0.13-ha field, the disease incidence was 50%–60%, causing serious economic losses. Based on morphological characteristics and molecular identification, as well as confirmation of pathogenesis following Koch's postulates, the causal agent was identified as Fusarium foetens. To our knowledge, this study is the first report of F. foetens as a pathogen on tobacco causing root and stem rot in Guizhou, China. The identification of the pathogen could lay the basis for its sustainable management in future.
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.
