While the pesticide formulations are widely used for pest control, the combined effects of these formulations with adjuvants on droplet behavior, spraying characteristics, and pest control still need to be studied. To clarify their impact on droplet behavior, spraying characteristics, and control efficacy, six formulations of acetamiprid and six adjuvants were examined. A series of laboratory and field experiments were conducted to analyze the physicochemical properties, toxicity against cotton aphids, droplet deposition characteristics, and droplet drift. The results indicated that 5% acetamiprid micro-emulsion (ME) enhanced the physicochemical features and effectiveness in pest control compared to other formulations. The nongjianfei considerably enhanced the efficiency of all acetamiprid formulations when added. The addition of selected adjuvants to pesticide formulations improved the performance of certain physicochemical properties such as viscosity and surface tension and led to higher aphid mortality rates, demonstrating enhanced pest control effectiveness during the present study. In the field experiments, the combination effect of acetamiprid formulations and adjuvants exhibited a higher droplet size, coverage, and density within the cotton canopy. However, 5% acetamiprid ME was found to be most effective followed by nongjianfei. Furthermore, 5% acetamiprid ME with adjuvant reduced the droplet drift and provided better deposition when compared with other formulations. Overall, the combination of specific formulations and adjuvants led to improved physicochemical properties, enhanced droplet deposition characteristics, reduced spray drift, and increased pesticide deposition. These findings highlighted the significance of selecting appropriate pesticide formulations and adjuvants and provided a solid foundation for efficient pesticide spraying through UAVs.
虽然农药制剂被广泛用于害虫防治，但这些制剂与助剂对雾滴行为、喷雾特性和害虫防治的综合影响仍有待研究。为了阐明它们对雾滴行为、喷雾特性和防治效果的影响，研究了六种啶虫脒制剂和六种助剂。进行了一系列实验室和田间试验，以分析其理化性质、对棉蚜的毒性、雾滴沉积特性和雾滴漂移。结果表明，与其他制剂相比，5%啶虫脒微乳剂（ME）增强了理化特性和害虫防治效果。添加“农健飞”后，所有啶虫脒制剂的效率都有显著提高。在农药制剂中添加选定的助剂可改善某些理化性质，如粘度和表面张力，并导致更高的蚜虫死亡率，表明在本研究中害虫防治效果得到增强。在田间试验中，啶虫脒制剂和助剂的组合效应在棉株冠层内表现出更大的雾滴尺寸、覆盖率和密度。然而，发现5%啶虫脒ME最有效，其次是“农健飞”。此外，与其他制剂相比，5%啶虫脒ME与助剂组合减少了雾滴漂移并提供了更好的沉积效果。总体而言，特定制剂和助剂的组合导致理化性质改善、雾滴沉积特性增强、喷雾漂移减少和农药沉积增加。这些发现突出了选择合适农药制剂和助剂的重要性，并为通过无人机进行高效农药喷雾提供了坚实基础。
