Effects of adjuvants on deposition characteristics of spray droplets applied by plant protection unmanned aerial vehicle and control efficiency on Aphis gossypii
[目的]探明植保无人机喷施农药时添加助剂对雾滴沉积特性和棉蚜防治效果(防效)的影响.[方法]选用大疆T30 植保无人机在棉花蕾期进行田间喷雾试验,比较添加 6 种助剂(牙克透、倍达通、植物三餐、农健飞、奇功和倍倍加)对 39%螺虫·噻嗪酮悬浮剂的雾滴粒径、密度、覆盖率和沉积量及棉蚜防效的影响.[结果]与不添加助剂的对照相比,添加 6 种助剂均能提高棉花上部、中部和下部叶片上的雾滴密度、覆盖率和沉积量.添加倍倍加、倍达通处理的雾滴粒径、密度、覆盖率和沉积量均较大,棉株上部、中部和下部叶片上的雾滴密度、覆盖率和沉积量均显著高于对照处理.添加 6 种助剂的各处理在药后 1 d、3 d、7 d和 14 d对棉株上部、中部和下部棉蚜的防效均高于对照处理,其中,添加倍倍加处理的防效最好,倍达通处理次之.[结论]添加助剂倍倍加和倍达通可改善雾滴沉积特性,对棉蚜具有较好的防效,对 39%螺虫·噻嗪酮悬浮剂防治棉蚜具有很好的增效作用.
[Objective]T his research aims to explore the effects of adjuvants during pesticide spraying by plant protection unmanned aerial vehicle(UAV)on droplet deposition characteristics and control efficiency on Aphis gossypii.[Methods]Dajiang T30 UAV was selected to conduct a field spray experiment during the cotton budding stage.The effects of 6 adjuvants(Yaketou,Beidatong,Zhiwusancan,Nongjianfei,Qigong,and Beibeijia)in 39%spirotetramat buprofezin on the size,density,coverage,and deposition amount of droplets and control efficiency on A.gossypii were compared.[Results]Compared with the control without adjuvant,treatments with the adjuvants increased the droplet density,coverage,and deposition amount on the upper,middle,and lower leaves of cotton plant.The droplet size,density,coverage,and deposition amount treated with Beibeijia and Beidatong were all higher;of which the density,coverage,and deposition amount on the upper,middle,and lower leaves of cotton plants were significantly higher than those of the control treatment.The control efficiency on A.gossypii of treatments with adjuvants in the upper,middle,and lower parts of cotton plant was higher than that of the control treatment at 1 d,3 d,7 d,and 14 d after application.The control efficiency of the treatment with Beibeijia was the best,followed by the treatment with Beidatong.[Conclusion]The addition of Beibeijia and Beidatong can improve the deposition characteristics of droplets and has a good control effect on A.gossypii.It also has a good synergism on the control of A.gossypii with 39%spirotetramat buprofezin suspension.
