摘要
为寻找高效安全药剂用以防治豇豆蚜虫,保障豇豆质量安全和农户种植效益,2023年开展了豇豆蚜虫田间药剂筛选试验。对比分析表明:防治豇豆蚜虫以10%啶虫脒可湿性粉剂300 g/hm2处理的速效性最好,药后1 d的平均防效可达82.32%;其次是50%氟啶虫酰胺水分散粒剂150 g/hm2处理;速效性最差的是60%吡蚜酮水分散粒剂180 g/hm2处理,药后1 d的平均防效仅为21.97%。4种供试药剂处理的持效期均较长,药后10 d、15 d的平均防效均保持在99%以上。
In order to find efficient and safe insecticides against cowpea aphids,ensure the quality and safety of cowpea and farmers'planting benefits,field trials were carried out in 2023.The comparative analysis showed that the quick bioactivity of acetamiprid 10% WP 300 g/hm^(2) against cowpea aphids was the best,and the average efficacy reached to 82.32%on the 1st day after treatment.The quick bioactivity of pymetrozine 60%WG 180 g/hm^(2) was the worst,and the average efficacy was 21.97% on the 1st day after treatment.The four insecticides all had persistent bioactivities,the average efficacies were over 99%on the 10th,15th day after treatment.
