| 中文摘要:目的：室内筛选对人参黑斑菌有理想抑菌活性的低毒化学杀菌剂，为人参黑斑病防控提供参考依据。方法：采用平板培养法结合抑菌率及毒力测定，明确不同杀菌剂的抑菌效果。结果：新益甲托、金万霉灵和多菌灵对人参黑斑菌的毒力较好，EC50值分别为199.5、181.97和96.83 μg·mL-1；其次为代森锰锌、阿米西达和世高，EC50值分别为2041.7、3162.3和1258.9 μg·mL-1；其余杀菌剂的EC50值均偏高。结论：新益甲托对人参黑斑菌有较好的防病潜力，在确保病害防治效果及农药残留达标的前提下，可考虑将其用于人参黑斑病的田间防治。 |

| Abstract:Objective：To screen low mammalian-toxic pesticides in the library，and provide reference for the control of the leaf and stem blight disease caused by Alternaria panax Whetz in Panax ginseng.Methods：Plate-culturing method combined with the inhibition rate and toxicities were used to examine the efficiency of fungicides tested.Results：New Tono，golden mycophenolate and carbendazol existed the highest toxicity against Alternaria panax，and their EC50 values were 199.5 μg·mL-1，181.97 μg·mL-1 and 96.83 μg·mL-1，respectively.Then were Mancozeb，Amistar，and score with the EC50 values of 2041.7 μg·mL-1，3162.3 μg·mL-1 and 1258.9 μg·mL-1，respectively.The EC50 values of the other fungicides were higher.Conclusion：New Tono showed good disease controlling potential against Alternaria panax，which can be used for the control of ginseng leaf and stem blight disease in the field after ensure the disease controlling efficacy and pesticide residue. |
