Abstract: 【Objective】 The aim of this paper is to establish a new technology of reducing application and increasing effect of insecticides on corn borer by using new synergies with insecticides. 【Method】 By selecting Dajang T16 plant protection UAV as the application instrument, and taking the scientific application amount of 2 representative insecticides as the reduction baseline, the field control effect of corn borer under the coordinated application of 3 new synergistic agents (0, -15%, -30%) was compared and analyzed. 【Result】 The best control effect was 28 days after 15% reduction and 30% reduction, and the best control effect was 80.06% - 92.17%. The best synergistic effect was Huifeng when 20% chlorophenylbenzamide was used in combination with synergistic agent, and the highest was 13.80% in the combination of 20% chlorochlor benzamide and no synergistic agent in 28 days after administration of 15% and 30% of the drug, The best synergistic effect was Oaxony when the insecticide 34% ethoxoate was used in combination with the synergistic agent, and the highest synergistic effect was 2.77% compared with that without the addition of the synergistic agent, and the synergistic effect of the insecticide was the best when the insecticide was used in combination with the synergistic agent. Among them, 34% CS35.00 mL/667m² Maidao flight control agent 15.00 mL/667m² was the most effective. The control effect was 98.28% on 28 days after treatment; 34% CS29.75 mL/mu plus flight control agent 15.00 mL/667m² plus Oaxony 30.00 mL/667m² with the control effect: 92.47% after 28 days. The worst control effect was 34% CS24.50 mL/667m² plus Maidao flight control agent 15.00 mL/667m² plus 15.00 mL/667m² Huifeng enhancer 10.00 mL/667m², and the control effect was 53.92% on the 28th day after treatment. 【Conclusion】 It is completely feasible to reduce application by 30% on the basis of original scientific application level of flight prevention by adding new synergistic agents reasonably, but the synergistic effect of different synergistic agents is different to some extent. In actual production, it is necessary to use them according to the type and nature of pesticides.

摘要： 【目的】 基于新型增效剂与杀虫剂协同使用,研究农药减施增效技术。【方法】 选取大疆T16植保无人机做为施药器械,并以2种代表性杀虫剂的田间适宜用药量作为减药基线,对比分析3种新型增效剂协同使用减药处理(0%、-15%、-30%)下的玉米螟田间防效。【结果】 添加增效剂在减药15%水平及减药30%水平下药后28 d防效最佳的是激健,防效达80.06%～92.17%。20%氯虫苯甲酰胺与增效剂配合施用处理下增效效果最好的是辉丰,增效较不添加增效剂最高达13.80%;杀虫剂34%乙多 甲氧虫与增效剂配合施用处理下增效效果最好的是欧克森,增效较不添加增效剂最高达2.77%。其中34%乙多 甲氧虫CS35.00 mL/667m²+迈道飞防助剂15.00 mL/667m²防效最高,药后28 d防效为98.28%;其次34%乙多 甲氧虫29.75 mL/667m²+迈道飞防助剂15.00 mL/667m²+欧克森增效剂30.00 mL/667m²药后28 d防效是92.47%;防效最差的是34%多乙 甲氧虫CS24.50 mL/667m²+迈道飞防助剂15.00 mL/667m²+辉丰增效剂10.00 mL/667m²,其药后28 d防效为53.92%。【结论】 添加新型增效剂,实现减施30%是完全可行的,但不同增效剂之间的增效作用存在一定差异,在实际生产中,应根据农药种类及性质等合理搭配使用。
