33％高效氯氟氰菊脂·吡虫啉SC防治甘蔗绵蚜虫田间药效试验

摘要

试验结果表明,33%高效氯氟氰菊脂·吡虫啉 SC 对甘蔗绵蚜虫有很好的防治效果,参试的3个剂量375 g/hm2(a. i. 123.8 g/hm2)、300 g/hm2(a. i. 99.0 g/hm2)、250 g/hm2(a. i. 85.5 g/hm2)在药后7天的防效均在99.7%以上.推荐使用剂量为250 g/hm2(a. i. 85.5 g/hm2)和300 g/hm2(a. i. 99.0 g/hm2).%Field tests revealed that lambda-cyhalothrin·Imidacloprid 33% SC had good effect on controlling sugarcane aphids. All 3 application rate, i.e. 375 g/hm2(a. i. 123.8 g/hm2), 300 g/hm2(a. i. 99.0 g/hm2), 250 g/hm2(a. i. 85.5 g/hm2), showed control effects higher than 99.7% 7 days after application. Recommended application rates are 250 g/hm2(a. i. 85.5 g/hm2) and 300 g/hm2(a. i. 99.0 g/hm2).
