摘要
选择10种高效、低毒、低残的化学杀菌剂对人参黑斑病防治进行了田间药效试验。结果表明,异菌脲、腐霉利和代森锰锌等是防治人参黑斑病的较好药剂,其中异菌脲因全年用药5次的发病率为0,相对防效达100%,并对人参具有刺激生长、延长绿叶期的作用,使参根增重16.21%,可作为农田栽参防治人参黑斑病的特效药。在农田栽参大面积黑斑病防治上可推广异菌脲、腐霉利、代森锰锌、粉锈宁等药剂,其中异菌脲和代森锰锌2种药剂交替使用将有效控制人参黑斑病的发生发展,从而大幅度提高人参产量。
10 high-efficiency,low-toxicity,and low-residual chemical fungicides were selected to conduct field trials on the prevention and treatment of ginseng black-fleck disease.Field efficacy trial showed that effect of iprodione,procymidone and mancozeb were better than other fungicides.Incidence of black-fleck disease was zero by applying iprodione on ginseng,while the relative control effect reached 100%.They stimulated the growth of ginseng,prolonged the greenery period,and increased the weight of ginseng root by 16.21%,and could be used as specific pesticide to control black-fleck disease of ginseng.In the prevention and control of black-fleck disease on large areas of ginseng grown in farmland,chemicals such as iprodione,procymidone,mancozeb,and triadimefon could be promoted.Iprodione and mancozeb were used as specific drugs to prevent and treat ginseng black-fleck disease.The alternating use of the two fungicides will effectively control the occurrence and development of ginseng black-fleck disease,thereby greatly increasing the yield of ginseng.
