| 中文摘要: |
| 为有效控制玉米后期叶斑病，本研究通过人工接种和自然发病两种方式，针对玉米小斑病、南方锈病和弯孢叶斑病进行了叶斑病防治技术的研究。结果表明，选用10%苯醚甲环唑WG和45%丙环唑ME，在玉米大喇叭口期采用机械喷雾的方式施药1次，对玉米小斑病、南方锈病和弯孢叶斑病都具有一定的防治作用，其中10%苯醚甲环唑WG对小斑病的最高防效为63.83%，挽回产量14.52%。两种药剂对弯孢叶斑病的最高防效都在60%以上，挽回产量最高达11%，但对南方锈病的防治效果并不理想，最高为29.91%。 |
| 英文摘要: |
| To find the effective control method for southern corn leaf blight, southern rust and Curvularia leaf spot on the late growth stage of corn, two fungicides were applied on corn whorl stage after artificial inoculation and naturally infection, respectively. The control efficacy of the two fungicides and their effects on yield were evaluated. The results showed that both difenoconazole 10% WG and propiconazole 45% ME had certain control effects against leaf spots artificially inoculated and naturally infected．Among all treatments, difenoconazole 10% WG showed higher control efficacy on southern corn leaf blight than others with control efficacy of 63.83% and saved the yield by 14.52%. The control efficacy of the two fungicides on corn Curvularia leaf spot were over 60% and the yields were 11% higher than that of the control. While their control efficacy on the southern rust was lower as 29.91%. |
