摘　　要：[目的]筛选防治小麦白粉病的新制剂,以替代三唑酮或与之轮换使用。[方法]通过小区试验研究13种药剂对小麦白粉病的防治效果及安全性。[结果]40%环丙唑醇WP 300 ml/hm2对小麦白粉病的防治效果较好,第2次施药后10 d的防效达到95.23%;其次分别是12.5%氟环唑SC 900 g/hm2、25%乙嘧酚ME 1 200 g/hm2、50%醚菌酯WG 150 g/hm2,第2次施药后10 d的防效分别为82.45%、78.34%和70.33%。参试药剂在连续使用2次的情况下,对小麦较安全。[结论]40%环丙唑醇WP可在小麦生产上大面积推广使用,是实施小麦综合防控技术的理想选择。12.5%氟环唑SC、25%乙嘧酚ME、50%醚菌酯WG均可替代三唑酮及其复配剂作为防治小麦白粉病的理想药剂。[ Objective] New reagents against wheat powdery mildew were screened out to substitute Triadimefon or rotationally use. / Method ] Control effects of.13 kinds of reagents against wheat powdery mildew and safety to wheat were studied through plot test. [ Result] 40% Cypro- conazole WP 300 ml/hm2 had good control effect on wheat powdery mildew, and the control effect in 10 days of the second applying reached 95.23% , secondly for 12.5% Epoxiconazole SC 900 g/hm2, 25% Ethirimol ME 1 200 g/hm2 and 50% Kresoxim-methyl WG 150 g/hm2, and control effects in 10 days of the second applying reached 82.45%, 78.34% and 70.33%, respectively. A1 the reagents were safe to wheat after two continuous applying. [ Conclusion] 40% Cyproconazole WP could be used widely in wheat production, and it was ideal selec- tion for apply wheat comprehensive prevention and control technology. 12.5% Epoxiconazole SC, 25% Ethirimol ME and 50% Kresoxim- methyl WG could be used to substitute Triadimefon or rotationally use.
