【摘要】 玉米是我国种植面积最大的粮食作物，大斑病、小斑病、灰斑病等叶斑病在生产上多发重发，造成严重的产量损失。近年来，随着全球气候变化和我国耕作制度变革，玉米叶斑病的种类和发生流行规律发生了新变化，一些新型叶斑病在局部地区暴发为害，对玉米生产和国家粮食安全造成严重威胁。本文综述了我国玉米主要叶斑病发生现状，分析了不同叶斑病病原菌的致病机制，介绍了玉米叶斑病的相关抗病基因，总结了玉米叶斑病的综合防控技术，并针对当前面临的防控难题，提出了构建玉米叶斑病精准防控体系的建议，以期提升我国玉米叶斑病防控水平，为我国粮食安全生产提供科技支撑。更多还原

【Abstract】 Maize is the most widely cultivated grain crop in China. However, maize leaf spot diseases(MLSDs) frequently cause severe damage nationwide. In recent years, significant shifts have occurred in the diversity and epidemiology of MLSDs. Several emerging leaf spot diseases have recently caused outbreaks in China, posing a serious threat to maize production and food security. This paper reviews the current occurrence status of major MLSDs in China, analyzes the pathogenic mechanisms of different MLSD pathogens, introduces the relevant disease-resistant genes of MLSDs, and summarizes the integrated management technologies of MLSDs. To address current control challenges, we propose constructing a precision MLSDs prevention system, aiming to enhance disease control efficacy and provide scientific support for national food security.更多还原
