摘要

石栎属（Lithocarpus henryi）是一种广泛分布于中国南方的珍贵木本植物，在园林绿化、工业和食品工业中有着广泛的用途。2024年8月，在南昌发现了典型的炭疽病症状。为了确定病原菌是否为炭疽杆菌，本研究采用科赫假设，通过分离病原菌、检测致病性、再分离病原菌。根据病原菌形态特征和多位点系统发育分析，确定该病原菌为暹罗炭疽菌。据我们所知，这是第一次报道由C. siamense引起的L. henryi叶枯病。本研究拓展了对C. siamense寄主的认识，为该病的防治提供了理论基础。

First report of Lithocarpus henryi leaf blight caused by Colletotrichum siamense in China

Lithocarpus henryi is an valuable woody plant widely distributed in southern China, and has a wide range of uses in landscaping, as well as in industry and the food industry. In August 2024, typical anthracnose symptoms were observed on leaves of L. henryi in Nanchang, China. To determine whether the causative agent was Colletotrichum, Koch's postulates were applied in this study through pathogen isolation, pathogenicity testing, and re-isolation of the pathogen. Based on morphology characteristics and multi-locus phylogenetic analysis, the pathogen was identified as Colletotrichum siamense. To the best of our knowledge, this is the first report of L. henryi leaf blight caused by C. siamense. This study expands the understanding of C. siamense hosts and provides a theoretical foundation for the prevention and control of this disease.

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.
