摘 要: 进行了6种新型杀菌剂对玉米褐斑病的田间药效试验,分析该病害的发生与流行情况,调查各杀菌剂对玉米产量的影响。结果表明:20%三唑酮EC对玉米褐斑病的田间防效最优,50%多菌灵WP对玉米褐斑病的田间防效较差;三唑酮处理的小区玉米平均产量最高。 The control effect was analyzed to several original fungicides against the corn brow spot through field experiment.The safety was investigated to the fungicides on corn and the yield was measured.The results showed that Triadimef was not only the most excellent on the control effect against corn brown spot but also the average yield of the experimental plot was increased significantly than others.But the control effect of Carbendazim is poor.In other words,Triadimefon on corn brow spot has played an effective role in prevention.
