摘要
农药药液对靶润湿沉积是剂量传递体系中的重要过程。在农药制剂中添加适宜的表面活性剂,可提高药液在靶标表面的润湿沉积,进而实现农药有效成分的渗透和传输,提高防治效果。文章综述了靶标界面结构性质的相关研究进展,探讨了表面化学成分和表面拓扑形貌对固体表观表面自由能的影响,并分别阐述了不同表面活性剂对药液在表面化学成分均一的光滑固体表面、粗糙固体表面以及表面化学成分复杂的植物叶片表面的润湿沉积行为,探索了农药制剂研发的新思路和新方法,以期为提高农药有效利用率,实现减施增效目标提供理论依据。
The wetting and deposition behaviors of pesticide droplet on target surfaces are the important processes in dose transfer system.The addition of appropriate surfactants in pesticide formulation is an effective method to improve the wetting and deposition properties on target surfaces,which will result in the infiltration and transmission of active ingredient to prevent plants from harmful organisms.Recent research progress on target surfaces properties,and the influence of surface chemical composition and surface morphology on the apparent surface free energy of solid were reviewed.The wetting and deposition behaviors of surfactants on smooth,rough solid surfaces with onefold surface chemical composition and plant leaf surfaces with complex surface chemical composition were summaried respectively,in order to assist the development of new strategies and methods for the preparation of pesticide formulations.Recent advances in this research area can provide theoretical basis for improving the effective pesticide utilization with the addition of surfactants,and realize the effciency of chemical pesticide application.
