摘　　要：松落针病是世界性松类针叶常见病害之一,近几年,此病害在北京市发生比较严重。通过对油松落针病大量的野外观察和对永定河休闲森林公园油松落针病发病率和感病指数的调查,对北京油松落针病的发生发展规律进行了初步分析。结果表明:营林措施不能降低油松落针病的发病率,但是能降低感病指数;化学防治方面,多菌灵和石硫合剂的防治效果最好;综合防治的效果比单一措施防治效果好;在防治时间上,4、5月份防治效果最佳。Needle cast on Chinese pine is common pine diseases in the world.In recent years,this disease has occurred seriously in Beijing.Through field observation and investigation of the incidence and disease index,the occurrence and development patterns of needle cast on Chinese pine in Beijing were analyzed.The results of the control test showed that the forest management measures can-not reduce the incidence of the pine disease,but can reduce the disease index.In terms of chemical control,the control effect of Carbendazim and lime sulfur is best.The effect of comprehensive prevention and control is better than that of single measures.The best effect was achieved in April and May.
