| 中文摘要: |
| 氟啶虫胺腈是一种专门防治刺吸式口器害虫的全新杀虫剂。本文以柑桔矢尖蚧和桔二叉蚜为防治对象,开展了22%氟啶虫胺腈SC田间药效试验。结果表明：药后14d,22%氟啶虫胺腈SC各处理对柑桔矢尖蚧防治效果为67.71~80.73%；药后28d,防治效果可达83.29%以上,其中高浓度处理防治效果可达92.08%。药后1d,22%氟啶虫胺腈SC各处理对桔二叉蚜防治效果达93.36~96.93%；药后7d,防治效果达到最高,其防治效果为97.26%~100%；药后14d,防治效果仍然可达92.04%以上。22%氟啶虫胺腈SC对柑桔矢尖蚧和桔二叉蚜具有优异防治效果和良好的安全性,可大面积在柑桔上使用,推荐使用浓度为3000~4000倍液喷雾。 |
| 英文摘要: |
| Sulfoxaflor is a novel sulfonylimide insecticides against sucking-mouthpart insect pests with high ef?cacy and low usage. Field efficacy trials were conducted to determine the field efficacy of sulfoxaflor 22% SC against Unaspis yanonensis and Toxoptera aurantii. The results showed that the average field effects of sulfoxaflor 22% SC against Unaspis yanonensis were 67.71~80.73% and 83.29%~92.08% 14 and 28 days after application, respectively. The field experiment also indicated that the average field effects of sulfoxaflor 22% SC against Toxoptera aurantii were 93.36~96.93%,97.26%~100% and above 92.04% of 1, 7 and 14 days after treatment, respectively. Based on these results, sulfoxaflor 22% SC had excellent ef?cacy against two pests, and has safety of natural enemies. Therefore, sulfoxaflor 22% SC could be used as the substitited pesticide to control Unaspis yanonensis and Toxoptera aurantii with concentrations of 55.0~73.3 mg.L-1 |
