Abstract

Polygonatum cyrtonema Hua (“yellow essence”) belongs to the family Liliaceae and is a valuable component of Chinese medicine. In October 2024, a survey of a Chinese herbal medicine planting base in Kaili City, Guizhou Province, found that P. cyrtonema Hua was affected by a serious disease with an incidence of 35–60 % that substantially reduced its yield and quality and, commensurately, economic return. Koch's postulates, molecular phylogenetic analysis, and morphology confirmed Stemphylium xanthosomatis as the causative pathogen. This is the first report of S. xanthosomatis infecting P. cyrtonema Hua. This study enriches the pathogen diversity database of P. cyrtonema Hua and provides an essential theoretical foundation for disease diagnosis and targeted management strategies.

黄体茎蚜引起黄精叶斑病在国内首次报道

黄精（Polygonatum cyrtonema Hua）属于百合科植物，是中药的重要成分。2024年10月，对贵州省凯里市中药材种植基地的调查发现，花青藤患了一种严重的病害，发病率为35 - 60%，严重影响了其产量和质量，并相应地降低了经济效益。科赫的假设、分子系统发育分析和形态学证实了黄体茎孢是致病病原体。本文为首次报道黄体索菌感染华胞单胞菌的病例。本研究丰富了华胞单胞菌病原菌多样性数据库，为疾病诊断和有针对性的管理策略提供了必要的理论依据。

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.
