摘　　要：选择5种杀菌剂拌种防治马铃薯枯萎病,以期筛选出有效的防治药剂,为大田生产提供理论依据。结果表明:5种杀菌剂拌种防治马铃薯枯萎病均安全有效,但是各药剂之间防效存在显著差异,2.5%咯菌腈SC的病株率、病薯率、病情指数最低,防效最高,分别为11.7%、16.5%、4.92、78.33%,10%苯醚甲环唑WG次之,为13.3%、17.3%、4.95、78.20%,二者之间差异不显著。72%霜脲·锰锌WP拌种对马铃薯枯萎病的防效为72.92%。这三种杀菌剂均可作为马铃薯枯萎病的防治药剂,在生产上推广应用。5种药剂拌种,块茎产量均有增加,增产幅度4.19%～8.42%。In order to select the effective cure for potato blight, it has selected five species of fungicide to carry on theexperiment. The results showed that all the five fungicides were safe and effective, but there was a significant differencebetween them. It was found that that anti-effect of the agent of dipteronitrile in 2.5 % of the medicine agent was up to78.33% , and the strain rate, disease rate and disease index were all the lowest, 11.7% , 16.5% , 4.92 and 78.33%respectively. The control effect of 10% benzole was 13.3%, 17.3%, 4.95 and 78.20% respectively. The effect of 72%cream urea manganese zinc WP on potato blight was 72.92%. The five fungicides can be used as the control agents forpotato blight and to provide the theoretical basis of the field production.
