摘　　要：为筛选防治小麦白粉病的有效药剂,对5种杀菌剂进行了田间防效试验。结果表明,在小麦白粉病发生初期,分别使用5%己唑醇ME 60 g/hm2(有效成分用量,下同)、43%戊唑醇SC96.75 g/hm2、12.5%烯唑醇WP 93.75 g/hm2和20%烯肟.戊唑醇SC 120 g/hm2,对水750 L/hm2均匀喷雾,药后10～20 d的防效均可稳定在83%以上。In order to screen excellent,low-toxic and safe fungicides for controlling wheat powdery mildew,the control efficiencies of five fungicides were compared by field trials.The results showed that the control efficiencies of four of them were all over 83% on the 10th and 20th days after spraying.These fungicides and dosages of active ingredients were hexaconazole 5% ME 60 g/hm2,tebuconazole 43% SC 96.75 g/hm2,diniconazole 12.5% WP 93.75 g/hm2 and SYP-1620 ＋ tebuconazole 20% SC 120 g/hm2.The fungicides were sprayed with water 750 L/hm2.
