摘　　要：室内及田间试验结果表明:烯肟菌胺对瓜类白粉病有优异的防治效果。盆栽条件下烯肟菌胺对黄瓜白粉病的杀菌活性(EC90值)为4.32mg/L,田间小区试验烯肟菌胺在40～80ga.i./hm2的剂量下施药2～3次,能有效的控制瓜类白粉病的危害,烯肟菌胺与戊唑醇组成的混剂对瓜类白粉病也同样具有良好的防治作用。5%烯肟菌胺EC和20%戊唑醇·烯肟菌胺SC对靶标作物(黄瓜)安全。The results showed that SYP-1620 is a highly active fungicide against powdery mildew of cucurbit crops both in laboratory and in field tests. The ECg0 value of SYP-1620 is 4.32 mg/L in pot tests. SYP-1620 controls cucurbits powdery mildew in fields at the rate of 40-80 g a.i./ha and 2-3 applications. The mixture of SYP-1620 plus tebuconazole also has high effective on cucurbits powdery mildew. SYP-1620 5% EC and tebuconazole.SYP-1620 20% SC are safe to target plants （cucumber）.
