摘　　要：为筛选防治黄瓜白粉病的高效、低毒、安全杀菌剂,对戊唑醇等7种杀菌剂进行田间药效试验。结果表明:43%氟菌·肟菌酯SC 192.6 g/hm^2、300 g/L醚菌·啶酰菌SC 270 g/hm^2处理的防效较高,病指防效分别为88.69%和83.30%;430 g/L戊唑醇SC 96.75 g/hm^2、37%苯醚甲环唑WG 90 g/hm^2、36%硝苯菌酯EC 216 g/hm2处理的病指防效分别为78.75%、73.23%和74.55%;250 g/L嘧菌酯SC 337.5g/hm^2、250 g/L吡唑醚菌酯EC 150 g/hm^2处理的防效较差,病指防效分别为49.40%和47.78%。To screen excellent,low-toxicity and safe fungicides for controlling cucumber powdery mildew,seven fungicides were tested in field efficacy trials.The results showed that the field efficiencies of fluopyram ＋ trifloxystrobin43% SC 192.6 g/hm^2 and kresoxim-methyl ＋ boscalid 300 g/L SC 270 g/hm^2 were high,the disease index control effects were 88.68% and 83.30%,respectively.The field efficiencies of tebuconazole 430 g/L SC 96.75 g/hm^2,difenoconazole37% WG 90 g/hm^2 and meptyldinocap 36% EC 216 g/hm2 were 78.75%,73.30% and 74.55%,respectively.The field efficiencies of azoxystrobin 250 g/L SC 337.5 g/hm^2 and pyraclostrobin 250 g/L EC 150 g/hm^2 were poor,the diseased index control effects were 49.40% and 47.78%,respectively.
