Effects of adjuvants on deposition characteristics of spray droplets applied by plant protection unmanned aerial vehicle and control efficiency on Aphis gossypii
摘要
Abstract
[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.关键词
