衫木顶枯病病原菌(pestalotiopsis apiculatus(Huang)Huang)的确定及病原生物学特性业经发表。几年来通过调查表明,该病害遍及全省各地,尤溪、沙县、南平、光泽、上杭等县更为严重,一些苗圃苗木顶枯病(尖枯病)发病率超过50％以上。苗木发病之后,高生长达不到出圃的要求,不可以上山造林,有营林地而没有苗木,导致造林计划不能完成,影响用材林基地建设的进展。为有效防治该病害,1982年以来对病害进行了较完整的防治试验。
Identification and pathogenicity of pestalotiopsis apiculatus (Huang) Huang has been published. In recent years, the survey shows that the disease spreads all over the province. Especially in Youxi County, Shaxian County, Nanping County, Guangze County and Shanghang County, the incidence of seedling blight (blight) in some nurseries exceeds 50%. After the emergence of seedlings, high growth can not reach the requirements of the nursery can not be afforestation, afforestation and no seedlings, resulting in afforestation program can not be completed, affecting the progress of the construction of timber base. In order to effectively prevent and treat the disease, a complete prevention and control test has been carried out on the disease since 1982.
