摘要
由散斑壳菌Lophoder mium sp.引起的落针病是银杉的一种重要叶部病害,导致针叶大量提早脱落,影响树木生长甚至濒于死亡。百菌清、多菌灵、甲基托布津等杀菌剂对病原菌子囊孢子萌发的抑制作用较强,以营林为主、药剂防治为辅的防治方法能控制该病的发生与流行。
Lophodermium sp. was an important pathogen causing needle cast on Cathaya argyrophylla, resulting in the early defoliation, growth decline and death. The result of the experiment showed fungicides such as chlorothalonil, carbendazim and Topsin-M had distinct control effect on the ascospore germination of Lophodermium sp. ; Afforestion, combined with fungicides control could depress the epidemics of the disease.
