摘要
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。
The results of study in two consecutive years showed that Sphaeropsis shoot blight on MongolianScots pine(Pinus sylvestris var. mongolica) can be effectively controlled by applications of fungicides. Tenfungicides such as thiophanate-methyl- triadimefon, zineb- carbendazol. copper hydroxide, Tuzet, chlorothalonil and benomyl were tested. The systemics carbendazol- benomyl and thiophanate-methyl proved tobe the most effective and dependable fungicides. There was no significant difference in effectivenessbetween weekly and biweekly applications of fungicides from mid-June to mid-September to controlSphaeropsis shoot blight on oneAiyear-old seedlings of Mongolian Scots pine. Therefore, biweeklyapplications are recommended.
