李树根部病害以根癌病最为常见。根癌病可为害多种植物,其病原菌传播方式较多,主要可随苗木运送远距离传播,是生厂上重要的植物检疫病害之一。目前,生产上常用的一些药剂对其疗效较差,加上很多农户对该病缺乏认识,在病害的防控上未予以重视。基于此,对李根癌目前的发生情况、综合防治具体措施研究有利李根癌的防治技术研究进展 Root blight root disease is most common. Root cancer can damage a variety of plants, the pathogen spread more, mainly with the seedlings transported long-distance transmission, is one of the important plant quarantine diseases. At present, some medicaments commonly used in production have poor curative effect on them, and many farmers lack a knowledge of the disease and have not paid much attention to disease prevention and control. Based on this, the current situation of Ligen cancer, comprehensive prevention and control measures to study the research progress of prevention and treatment of Ligen cancer
