[目的]研制20%ZJ4014油悬浮剂的配方,为ZJ4014的进一步开发提供支持。[方法]通过对不同载体的油、乳化剂、分散剂进行筛选优化,制备20%ZJ4014油悬浮剂,并对其物化性能指标进行测定。[结果]获得了物化性能稳定的20%ZJ4014油悬浮剂配方。田间试验结果表明20%ZJ4014油悬浮剂对小菜蛾的防效高于20%ZJ4014悬浮剂。[结论]ZJ4014油悬浮剂具有良好的物化稳定性且活性较高,是重要的开发方向。 [Objective] To develop the formulation of 20% ZJ4014 oil suspending agent and provide support for the further development of ZJ4014. [Method] The 20% ZJ4014 oil suspending agent was prepared by screening and optimizing the oil, emulsifier and dispersant of different carriers, and its physicochemical properties were measured. [Result] The formulation of 20% ZJ4014 oil suspension was obtained with stable physical and chemical properties. Field trials showed that 20% ZJ4014 oil suspending agent against Plutella xylostella more than 20% ZJ4014 suspending agent. [Conclusion] ZJ4014 oil suspending agent has good physical and chemical stability and high activity, which is an important development direction.
