摘要
在黄瓜白粉病菌抗药性产生的背景下,为评价新型复配农药己唑醇·乙嘧酚磺酸酯杀菌剂和4种传统农药对黄瓜白粉病的防治效果,本试验选用30%己唑醇·乙嘧酚磺酸酯ME,以25%乙嘧酚磺酸酯ME(嘧啶类)、50%多菌灵WP(苯并咪唑类)、250 g/L嘧菌酯SC(甲氧基丙烯类)、10%己唑醇SC(三唑类)4种传统药剂为对照,采用常规喷雾法进行大棚药效防治试验。结果表明:5种杀菌剂在适宜药剂浓度下对黄瓜白粉病都具有良好的防治效果,防效分别为77.63%、74.27%、66.70%、74.81%和71.81%。30%己唑醇·乙嘧酚磺酸酯ME的防治效果高于其他4种传统药剂,可以作为替代药剂在一些白粉病菌已产生抗药性的地区使用。
In order to evaluate the control effect of the new compound pesticide Hexaconazole and Bupirimate fungicide and four traditional fungicides on cucumber powdery mildew in the context of resistance of cucumber powdery mildew,30%Hexaconazole and Bupirimate ME and four traditional fungicides such as 25%Bupirimate ME(pyrimidine),50%Carbendazim WP(benzimidazole),250g/L Azoxystrobin SC(Strobilurin),10%Hexaconazole SC(triazole)were selected,and the sprayed by conventional spraying method to test the efficacy in the greenhouse.The results showed that the five fungicides had a good control effect on cucumber powdery mildew at the appropriate concentration.The control effects were 77.63%,74.27%,66.70%,74.81%and 71.81%,respectively.The control effect of the 30%Hexaconazole and Bupirimate ME is higher than that of the other four traditional agents.It can be used as an alternative agent in some areas where powdery mildew has developed fungicide resistance.
