Abstract

Epimedium sagittatum (Sieb. et Zucc.) Maxim., a perennial medicinal plant belonging to the Berberidaceae family, exhibits therapeutic efficacy by regulating renal physiological functions. From May to October 2024, a severe outbreak of anthracnose was observed in an E. sagittatum plantation in Jianhe County, Guizhou Province, China, with an incidence rate of approximately 25–80 %, causing severe losses, and research regarding anthracnose in E. sagittatum is limited. In this study, we aimed to identify the causative. Integrated molecular analysis of ITS, gapdh, act, tub2, chs-1, and his3 and morphological characterisation of conidia identified the isolated strains as Colletotrichum jiangxiense. Furthermore, experimental validation through pathogenicity assessments revealed that the disease symptoms were consistent with those documented under natural field conditions, confirming that C. jiangxiense as the causative pathogen. To our knowledge, this is the first report of C. jiangxiense causing anthracnose in E. sagittatum.

摘要矢状淫羊藿（Epimedium sagittatum）炭疽菌江仙氏菌引起的炭疽病首次报道。调查)。的格言。来自中国贵州省

矢状淫羊藿（淫羊藿）调查)。的格言。小檗属多年生药用植物，通过调节肾脏生理功能发挥治疗作用。2024年5月至10月，中国贵州省剑河县一处箭形叶猴人工林发生了严重的炭疽病暴发，发病率约为25-80%，造成了严重的损失，目前关于箭形叶猴炭疽病的研究有限。在这项研究中，我们旨在确定病因。综合ITS、gapdh、act、tub2、chs-1和his3的分子分析和分生孢子的形态特征，鉴定分离菌株为姜仙ense炭疽菌。此外，通过致病性评估的实验验证表明，该疾病的症状与野外自然条件下的记录一致，证实了江仙花是致病病原体。据我们所知，这是第一次报道江仙梭菌引起矢状蝽炭疽病。

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.
