摘要

油茶是一种多功能木本食用作物，在中国广泛种植。自2024年以来，湖南常德市和株洲市的油桐普遍存在黑斑。通过形态学特征（菌落和分生孢子）和内部转录间隔区（ITS）、翻译扩增因子1- α基因（tef1）和肌动蛋白基因（act）的多位点系统发育分析，将病原菌从有症状的叶片中分离出来，鉴定为毛竹。用代表性分离株接种的叶片在油桐叶片上引起的疾病症状与田间观察到的症状相似。科赫的假设得到了从接种叶片中重新分离和鉴定病原体的支持。据我们所知，这是中国湖南省首次报道白顶霉引起油桐叶面病害的报道。这些发现将有助于制定科学的疾病管理策略。

First report of Phyllosticta capitalensis causing black leaf spot on Camellia oleifera in Hunan, China

Camellia oleifera is a multifunctional woody edible crop and is widely cultivated in China. Since 2024, black leaf spots were commonly observed on C. oleifera in Changde City and Zhuzhou City, Hunan Province, China. The pathogen was isolated from the symptomatic leaves and identified as Phyllosticta capitalensis based on morphological characteristics (colonies and conidia) as well as multi-locus phylogenetic analysis using the internal transcribed spacer region (ITS), translation elonation factor 1-alpha gene (tef1), and actin gene (act). Leaves inoculated with the representative isolates cause disease symptoms on C. oleifera leaves that are similar to those observed in the field. Koch's postulates were supported by pathogen re-isolation and identification from the inoculated leaves. As far as we know, this is the first report of P. capitalensis causing foliar disease on C. oleifera in Hunan Province, China. These findings will contribute to making scientific management strategies for 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.
