Difenthiuron-containing insecticidal composition and application thereof

The invention belongs to the field of agricultural pest control, and particularly relates to an insecticidal composition containing diafenthiuron. The insecticidal composition comprises the bistrifluron and the diafenthiuron which serve as active components, and the mass ratio of the bistrifluron to the diafenthiuron which serve as the active components is (1: 30)-(50: 1). The insecticidal composition disclosed by the invention has an obvious synergistic effect, not only can enhance the activity to target pests and enlarge the insecticidal spectrum, but also can reduce the resistance generated by single medication to achieve the effects of enhancing the effect and reducing the application. 本发明属于农业害虫防治领域，具体涉及一种含丁醚脲的杀虫组合物。所述的杀虫组合物包括活性成分双三氟虫脲和丁醚脲，所述的活性成分双三氟虫脲与丁醚脲的质量比为1:30～50:1。本发明所述的杀虫组合物具有明显的增效作用，不仅能够增强对靶标害虫的活性，扩大杀虫谱，同时还可以减少单一用药产生的抗性，达到增效减施的作用。
