摘　　要：樟子松移植苗枯梢病 Sphaeropsissapinea可以通过药剂有效地进行防治。移植前以 50 %多菌灵 wp 50 0倍液浸苗 ;在人工林中 ,内吸性杀菌剂甲基托布津、多菌灵为首选药剂 ;在树木新梢生长停止期和展叶中期 (辽西北为 6月初和 6月中旬 ) ,70 %甲基托布津 wp 1 0 0 0倍液或 50 %多菌灵 wp50 0倍液防治 2次。保护性杀菌剂百菌清效果不佳。适时的卫生伐对该病有明显的抑制作用。Sphaeropsis shoot blight in the transplants of mongolian scotch pine( Pinus sylvestris var. mongolica )could be effectively controlled by application of fungicides.Soaking the seedlings in Carbendazim solution(50% wp,diluted 500 times)just before transplantation in nursery achieved good result.In plantation the systemic Thiophanate methyl and Carbendazim proved to be the most effective and dependable fungicides.Two applications of Thiophanate methyl(70% wp,diluted 1000 times)or Carbendazim(50% wp,diluted 500 times)in a year,one close to the end of shoot elongation,the other in the middle of needle elongation(in the beginning and middle of June in Northwestern Liaoning),gave significant control.The protective fungicide Chlorothalonil proved to be ineffective.Sanitation cutting remarkably checked the disease,which should be carried out in time.
