桑青枯病(bacterial wilt)
桑青枯病(bacterial wilt)又名细菌性青枯病、细菌性枯萎病、瘟桑、疽桑，为害桑树全株的一种细菌性病害。在中国的广东发生，其中佛山地区发病最普遍。病原为茄青枯假单胞杆菌假单孢杆菌属，学名为Pseudomonas solanacearum Smith。菌体短杆状，无芽孢，无荚膜，长度约0.8-1.9μM。极生鞭毛，多数一根，偶有3根。菌落圆形，平滑有光泽，湿润而呈粘液状，初期灰白色，以后分泌水溶性色素而使成褐色。在10-40℃范围内均可生长，以28-36℃生长最好，致死温度为53℃ 10分钟，适于生长的pH范围为5-9，以7-8生长最好。病原细菌能在土壤和遗落在土中的病株残体上越冬，由根部(或茎部)伤口侵入，引起初次侵染。发病后病菌从病株组织散落土壤中，带病苗木、接穗、插条等也是传病来源，并通过调运而作远距离传布。本病在4-11月间都可发生，而以8-10月间发病最多。高温多湿，尤以低洼积水地发病较重；桑树摘顶或剪伐可促进发病。病树地上部的症状主要表现为青枯，其中有些是全株叶片尚保持青绿而失水凋萎，有些则是从桑株的上、中部叶片的叶尖、叶缘先失水，然后变黄，褐而干枯，逐步扩展至全叶、全株。严重时病根的木质部变黑，根部腐烂、脱落。实行检疫，封锁病区，严格控制病害向无病区扩展和从有病区传入，培育实生苗时，要选用无病地作苗圃，用无病的桑苗和桑枝作嫁接材料，将病株挖起，集中烧毁，并进行病迹地土壤消毒，发病严重的地块，实行与甘蔗、玉米、高粱、水稻等非寄主范围作物轮作。
