摘　　要：红松烂皮病(Cenangium acicolum(Fuch.)Rehm)在辽宁省发病面积达6×10~4ha,占全省红松林总面积的31.75％,损失材积16.5m^3/ha。全省防治面积1867ha,主要采取管林技术措施,有重点的辅以35％汽油焦化腊涂干防治取得了明显的防治效果和经济效益、社会效益及生态效益。This disease occurs in the area of 6667ha in Liaoning Province, approximately 31.75% of the korean pine forest of this province, which causes timber loss of 16.05/ha. The pathogen Cenangium acicolum (Fuck.) Rehm. is a weak parasite, which invades the tree once a year from the wounds on the hranches of trunk. The disease occurance is related to the forest age, closing degree, slope direction, slope position, canopy position and whether the forest is mixed or pure, the integrated control techiniques include the proper forost managemant as the main method, and the chemical control as the subsidiary. On the recent years, 1867ha of the forest were cured and the social, esonomicol and ecological benefits were significant.
