摘要
[目的]筛选防治茶小绿叶蝉的安全、高效杀虫剂。[方法]于2016、2017年进行了田间药效试验。[结果]3种新型杀虫剂5%双丙环虫酯可分散液剂20 ga.i./hm^2、17%氟吡呋喃酮可溶性液剂90 ga.i./hm^2、22%氟啶虫胺腈悬浮剂50 ga.i./hm^2对茶小绿叶蝉具有较好的防效,药后3 d防效均在89.08%以上,药后14 d防效均在82.58%以上,持效期达14 d左右。[结论]筛选的3种新型杀虫剂均可作为防治茶园小绿叶蝉的有效药剂在生产上推广应用。
[Aims] This study aims to screen out safe and effective insecticides for control of Empoasca pirisuga Matumura. [Methods] Field efficacy trials were conducted in 2016 and 2017. [Results] Afidopyropen 5% DC 20 g a.i./ha,flupyradifurone 17% SL 90 g a.i./ha, sulfoxaflor 22% SC 50 g a.i./ha could effectively control the damage caused by E. pirisuga Matumura. The control effect were above 89.08% after 3 days after treatment, the control effect were above 82.58% after 14 days after treatment, indicating that the efficacy could last for 14 days. [Conclusions] The three new insecticides screened in this paper can be used as effective pesticides to control E. pirisuga Matumura.
