摘要:

研究旨在探讨一种复合型农药增效剂对杀虫剂的增效作用,该增效剂主要成分包括复合型改性植物油、复合型糖醇类物质以及非离子表面活性剂。设置不同浓度灭幼脲加增效剂的处理共计10组,以清水、清水加农药增效剂作为对照组,通过室内生物测定添加农药增效剂的灭幼脲对草地贪夜蛾幼虫的杀虫效果,及对草地贪夜蛾幼虫化蛹率的影响,来明确其增效作用。结果表明,施用灭幼脲30%与农药增效剂混剂72 h后的杀虫效果提升了46.55%。由此可见,农药增效剂对灭幼脲的杀虫效果具有增效作用。

Abstract:

This study aims to clarify the synergistic effect of pesticide synergists (which main ingredients are compound modified vegetable oil, complex sugar alcohols, non-ionic surfactant) on insecticide. A total of 10 groups with different concentrations of pesticide synergists were set up, two control treatments were set as water, water and pesticide synergists. The synergistic effect of insecticides was determined by indoor measurement of the effect of adding pesticide synergists on the larval killing of Spodoptera frugiperda and the effect of insecticide synergist on the pupation rate of Spodoptera frugiperda. The results showed that the insecticidal effect was improved by 46.55% after 72 hours of application of a mixture of 30% chlorobenzuron and pesticide synergist. From this, it can be seen that pesticide synergists have a synergistic effect on the control of chlorobenzuron.
