Abstract

Yulania denudata are widely cultivated in China and worldwide for their versatile uses. Thus, sustainable disease management requires critical knowledge of Y. denudata pathogens. In August 2022, a leaf blight disease was observed on Y. denudata mature tree in the campus of Nanjing Forestry University, located in Xuanwu district, Nanjing City, Jiangsu Province, China. Isolations from the symptomatic leaves yielded Botryosphaeria-like fungal isolates. Phylogenetic analysis utilizing internal transcribed spacer (ITS), translation elongation factor 1-α (EF1-α), and β-tubulin (TUB) of isolate YL 2–1, YL 4–2, YL 5–3, YL 6–1 confirmed the species as Botryosphaeria dothidea. Leaf inoculations with the representative isolate YL 6–1 produced disease symptoms on Y. denudata. Finally, Koch's postulates were established by re-isolation and re-identification of B. dothidea isolates from the inoculated leaves. To the best of our knowledge, this is the first report of B. dothidea causing foliar disease symptoms on Y. denudata in China. These findings will contribute to developing disease management strategies for Y. denudata leaf blight.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
