[目的]对比了几种药剂对黄瓜霜霉病、小麦白粉病的防治效果。[方法]进行了几种药剂对2种病害室内盆栽法毒力测定试验和田间药效试验。[结果]氟噻唑吡乙酮、氰霜唑、氟菌·霜霉威对黄瓜霜霉病有非常优异的防治效果,防治效果达到80%以上。氟唑菌酰羟胺、丙硫菌唑对小麦白粉病有非常优异的防治效果,防治效果达到90%以上。[结论]氟噻唑吡乙酮、氰霜唑、氟菌·霜霉威可以很好的应用在黄瓜霜霉病防治上。氟唑菌酰羟胺、丙硫菌唑可以很好的应用在小麦白粉病防治上。

[Aims] This study aims to compare control efficacy of several fungicides against cucumber downy mildew and wheat powdery mildew. [Methods] Pot experiment and field trial were applied. [Results] In field trials,oxathiapiprolin, cyazofamid and fluopicolide·propamocarb indicated good effect of more than 80% control against cucumber downy mildew. Pydiflumetofen and prothioconazole showed significantly better control of above 90%against wheat powdery mildew. [Conclusions] Oxathiapiprolin, cyazofamid and fluopicolide·propamocarb can provide perfect efficacy against cucumber downy mildew. Pydiflumetofen and prothioconazole can be applied to control wheat powdery mildews.
