摘　　要：采用田间喷施的方法,选用裕丰310和加多兴939青贮玉米品种,于玉米小喇叭口期和大喇叭口期各喷施240 g/L氯氟醚·吡唑酯乳油1次,以验证和评价对青贮玉米大小斑病的防治效果及提质增产作用。结果表明,氯氟醚·吡唑酯对青贮玉米大小斑病具有显著防治效果,同时还可以增加玉米植珠茎秆粗度,提高植株高度,对青贮玉米生物产量有明显的促进作用。In order to verify and evaluate the control effect,quality improvement and yield improvement of silage maize varieties Yufeng 310 and Jiaduxing 939,240 g/L of chloroflurane pyrazolate missible oil were sprayed once in maize spot and maize southern leaf blight.The results showed that chloroflurane pyrazolate had a significant effect on the control of maize spot and maize southern leaf blight,and could also increase the stalk coarser and plant height,which had a significant effect on the biological yield of maize silage.
