叶斑病经病原物侵害后主要在叶片上发生各种局部坏死性病斑的植物病害。可由真菌、细菌、线虫引起。病原物以真菌为主,如尾孢属(Cercospora)、长蠕孢属 (Helminthosporium)、壳针孢属(Septoria)、叶点霉属 (Phyllosticta)、链格孢属(Alternaria)等；此外,黄色单胞杆菌属(Xanthomonas)和假单胞杆菌属(Pseudomonas)的细菌也可引起叶斑病。有些病原物存在不同的生理小种。常见的叶斑病有由真菌引起的玉米大斑病、玉米小斑病、橡胶麻点病、花生褐斑病、花生黑斑病、甜菜褐斑病、向日葵褐斑病、苹果褐斑病等，由细菌引起的棉花角斑病、水稻白叶枯病、大豆细菌性叶斑病等。叶斑病菌主要在植物病残组织和种子上越冬，成为下一代生长季的初侵染源。病菌多数靠气流、风雨，有时也靠昆虫传播。通常在生长季节不断侵染。叶斑病的流行要求雨量较大、降雨次数较多、温度适宜的气候条件,但也有对湿度要求不高的情况,如马铃薯早疫病。叶斑病造成局部坏死；仅少数可发展为系统侵染，如水稻白叶枯病的病菌侵入后在植株体内扩展，苗期症状不明显，至分蘖末期、孕穗初期呈现典型症状。防治主要侧重于抗病育种和清洁田园，适当结合栽培措施和化学防治。对果树叶斑病，药剂防治的效果较好。常用的药剂有波尔多液、代森锌、退菌特、百菌清、托布津、多菌灵等。对系统性侵染的叶斑病，以种子处理的效果较明显。
