松针褐斑病,〔Scirrhia acicola(Dearn.Siggers.〕原是美国南方松树的重要病害,寄主涉及松树24个种和变种,其中对长叶松(Pinus palustris)的为害最甚。我国于1958年由南京林业大学李传道在当地的黑松(Pinus thunbergii)上首次采得,认为病原菌就是美国松针褐斑病的无性阶段〔Lecanostiota acicola(thiim.)Syd〕。近年来,此病在我国南方一些省份的湿地松(Pinus elliotii)火炬松(P.taeda)和黑松上蔓延开来,局部地区为害日益严重,1984年被林业部定为国家森林植物检疫对象。我省六安、宣城、安庆、巢湖、徽州等地区也有松针褐斑病的分布,就目前调查材料
