摘要
为研究植保无人飞机喷雾参数对棉蚜防治效果的影响及评价助剂对药剂的增效作用,本研究通过田间试验分析了飞行高度、飞行速度和喷头型号等喷雾参数对棉蚜防效的影响,并评价了5种喷雾助剂ND-600、ND-800、G2801、倍达通和N380对22%氟啶虫胺腈悬浮剂(SC)和21%噻虫嗪SC的增效作用。结果表明:植保无人飞机飞行高度对棉蚜防效的影响显著,其中飞行高度为2 m时防效最佳,最优参数组合为飞行高度2 m,飞行速度3 m/s,喷头型号IDK120-01。添加助剂后,22%氟啶虫胺腈SC和21%噻虫嗪SC对棉蚜的防效有不同程度的提高,药后7 d,除ND-600外,ND-800、G2801、N380和倍达通对22%氟啶虫胺腈SC均有增效减量作用,其中ND-800的效果较好,G2801、倍达通和N380的增效作用一般;21%噻虫嗪SC对棉蚜的防治效果较好,除不添加助剂的处理外,其余处理药后7 d的防效均在90%以上,5种助剂的减量增效作用均较好。
In this work,the effect of plant protection unmanned aerial vehicle(UAV)spray parameters on the control of Aphis gossypii and the synergistic effects of spray adjuvants on two insecticides were evaluated.The effects of flight height,flight velocity and type of nozzles on the control of A.gossypii was analyzed by field experiments.In addition,the synergistic effects of 5 spray adjuvants(ND-600,ND-800,G2801,BEIDATONG and N380)for two insecticides(22%solfoxaflor SC and 21%thiamethoxam SC)were determined by field trials.The results indicated that spray parameters could significantly affect the control of A.gossypii.2 m was the best flight height.The optimum parameters combinations were as follows:flight height of 2 m,flight velocity of 3 m/s and nozzle type of IDK120-01.The results also showed that,after the addition of adjuvants,the field control effects of 22%solfoxaflor SC and 21%thiamethoxam SC were improved in different degrees.Except ND-600,7 days after the application,other adjuvants,including ND-800,G-2801,N380,Beidatong,have synergistic effects on22%solfoxaflor SC and ND-800.21%thiamethoxam SC had a good control efficiency for A.gossypii.Control efficiencies were all more than 90%after the usage of adjuvants,ND-600,ND-800,BEIDATONG,G2801 and N380 could all significantly increase the control efficiency of 21%thiamethoxam SC.
