摘要

从2022年到2023年，中国云南省一个药用植物种植基地爆发了严重的根腐病，这种植物具有很高的药用价值。受感染植株表现出典型的根腐病症状，从根部和根茎局部褐变开始，发展为基部叶柄腐病，最终导致叶片死亡和根茎腐烂。这次暴发造成了巨大的经济损失，发病率为50-60%。通过多基因系统发育分析（tub2、tef1-α和rpb2）和形态鉴定，确定了尖孢镰刀菌为病原菌，并通过体外人工接种进一步证实。本研究首次报道了尖孢镰刀菌是黄豆根腐病的病原，为黄豆根腐病的防治提供了有价值的信息。

Root rot disease of Polygala crotalarioides caused by Fusarium oxysporum in China

Polygala crotalarioides, a plant highly valued for its medicinal properties, suffered a severe root rot outbreak in a medicinal plant planting base in Yunnan Province, China, from 2022 to 2023. The affected plants exhibited typical root rot symptoms, beginning with localized browning of roots and rhizomes, progressing to basal petiole rot, and ultimately leading to leaf death and rhizome decay. This outbreak resulted in substantial economic losses, with an incidence rate of 50–60%. Fusarium oxysporum was identified as the causative agent through multigene phylogenetic analysis (using tub2, tef1-α, and rpb2) and morphological characterization, further confirmed by in vitro artificial inoculation. Our study is the first to report F. oxysporum as the cause of root rot in P. crotalarioides and provides valuable information for the prevention and control of this damaging 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.
