【Abstract】 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.更多还原
