为了有效控制樟子松苗木枯梢病的发生、进行了连续2a的试验研究。结果表明．樟子松苗木枯梢病可以通过药剂有效地进行防治。在甲基托布津、菌核净、三唑铜、朴海因、代森锌、多菌灵、可杀得、退菌特、百菌清和苯来特等10种药剂中，多菌灵（500×）、苯来特（800×）和甲基托布津（1000×）3种内吸性杀菌剂效果良好、稳定．应被视为首选药剂。对1年生播种苗在6月中旬至9月中旬施药．隔14d施一次药与隔7d施一次药效果没有明显区别．宜采用14d施一次药。
In order to effectively control the shoot blight of Pinus sylvestris var. Mongolica, two consecutive experiments were conducted. The results show.
