摘　　要：采用fmoxadone+霜脲氰(cymoxanil)(甲氧基亚胺基)乙酰胺、氟吗啉、嘧菌酯等5种药剂防治设施黄瓜霜霉病田间防治效果,试验结果表明:52.5%famoxadone+霜脲氰(cymoxanil)(甲氧基亚胺基)乙酰胺WG236.25 g/hm^2,25%嘧菌酯SC 187.5g/hm^2,60%氟吗啉WP 108.0 g/hm^2,对黄瓜霜霉病的防治效果显著,防效分别为93.71%、92.94%和90.87%。在发病初期每7 d施药1次,共2次,14 d供试杀菌剂防效均在90%以上,可在生产中选择应用。对设施黄瓜霜霉病防治策略上采取利用霜霉病菌和黄瓜生长要求的环境条件不同要求的生态防治和农业防治,合理化防的综合治理策略。Control effect of famoxadone ＋ cymoxanil , Azoxystrobin , flumorph, carbendazim and other fungicides on Cucumber Downy Mildew was investigated in greenhouse. The results showed that control effects of 25% Azoxystrobin SC1200X, 52.5% famoxadone ＋ cymoxanil WG2000X and 60% flumorph WP 500X on Cucumber Downy Mildew were over 90 %, 93.71%, 92.94 % and 90.87 %, respectively spraying one times for 7 d, spraying 2 times for 14 d. The ecological control countermeasures and agricultural control methods should be carried out to control Cucmnber Downy Mildew by the use of downy mildew fungicides and different environmental conditions requested by cucumber growth.
