Abstract

The Chinese yew (Taxus chinensis (Pilg.) Rehd) is a notable species renowned for its significant contribution to modern medicine. In November 2023, leaf blight disease was observed affecting Chinese yew nurseries in Meishan City, Sichuan Province, China, reducing quality. The causal agent was identified through isolation, morphological characterization, and phylogenetic analysis using the internal transcribed spacer (ITS), elongation factor 1-α (EF1-α) gene, and the second largest subunit of RNA polymerase II (RPB2). Pathogenicity tests were conducted, and the fungus was successfully reisolated from the symptomatic needle. The pathogen was identified as Fusarium fujikuroi. Biological characteristics were determined under optimal growth conditions. This study provides the first comprehensive identification of the leaf blight pathogen F. fujikuroi on Chinese yew.

引起红豆杉叶枯病的藤黑镰刀菌首次报道

中国红豆杉（Taxus chinensis, Pilg.）Rehd)是一种值得注意的物种，因其对现代医学的重大贡献而闻名。2023年11月，四川省眉山市红豆杉苗圃发现叶枯病，导致品质下降。利用内部转录间隔段（ITS）、延伸因子1-α (EF1-α)基因和RNA聚合酶II （RPB2）第二大亚基，通过分离、形态学鉴定和系统发育分析确定了致病因子。进行了致病性试验，成功地从有症状的针中分离出真菌。病原鉴定为藤黑镰刀菌。在最佳生长条件下测定其生物学特性。本研究首次对红豆杉叶枯病病原菌进行了全面鉴定。

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.
