白纹羽病是梨树重要的根部病害之一。该病开始发生于细根,然后扩展到侧根与主根。病菌以残留在土壤中的菌丝体、菌索或菌核越冬。翌年环境条件合适,菌索或菌核萌发产生菌丝引起新的侵染。病根、健根相互接触,随着根状菌索的延伸使病害传播、蔓延。为此,应从加强栽培管理入手,做到早检查、早发现、早防治,根除病害,保障梨树丰产。
White pattern feather disease is one of the important root diseases of pear. The disease begins with fine roots and then extends to the lateral root and the main root.
