Abstract

Sorghum is a globally grown crop for food and feed,as well as holds a crucial position in brewing industry in China. Anthracnose poses a major threat to both the yield and quality of sorghum. In August 2024, an outbreak of anthracnose affecting 90 % plants was observed in a sorghum cultivation area of Xingyi City, Guizhou Province, China. The typical symptoms started as irregular to oval maroon spots on the leaves, which later developed to wider necrotic lesions and produced a lot of fruiting bodies. To determine the causal agent, the fungus was isolated from the diseased and healthy junctions. Based on integrated evidence from morphological characteristics, multi-locus phylogenetic analyses (ITS, GAPDH, ACT, HIS3, TUB, and CHS-1), and pathogenicity assays, the pathogen was pinpointed as Colletotrichum truncatum. This study provides the first report of C. truncatum as the causative agent of sorghum anthracnose in China.

中国首次报道高粱炭疽病

高粱是一种全球种植的食品和饲料作物，在中国的酿造业中占有至关重要的地位。炭疽病对高粱的产量和品质都构成重大威胁。2024年8月，中国贵州省兴义市某高粱种植区发生炭疽病暴发，侵染90%的作物。典型的症状开始是不规则到椭圆形的栗色斑点在叶子上，后来发展到更广泛的坏死病变和产生大量的子实体。为了确定致病因子，从患病和健康的连接处分离真菌。基于形态学特征、ITS、GAPDH、ACT、HIS3、TUB和CHS-1多位点系统发育分析和致病性等综合证据，确定病原菌为炭疽菌（Colletotrichum truncatum）。本研究是国内首次报道高粱炭疽病的病原菌。

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.
