Insecticidal synergistic composition containing veratrine

The invention belongs to the technical field of pesticide research and development and specifically relates to insecticidal synergistic composition containing veratrine. The insecticidal synergistic composition containing the veratrine is characterized in that effective ingredients include the veratrine and lepimectin, and a weight ratio of the veratrine to the lepimectin is (1 to 50) to (50 to 1). The insecticidal synergistic composition disclosed by the invention has an obvious synergistic interaction effect, overcomes and delays pest resistance, expands a preventing and treating spectrum, has a quick insecticide speed and obviously improves a preventing and treating effect. 本发明属于农药研发技术领域，具体涉及种含藜芦碱的杀虫增效组合物。种含藜芦碱的杀虫增效组合物，其特征在于，有效成分为藜芦碱和lepimectin，所述藜芦碱和lepimectin的重量比为1:50-50:1。本发明的杀虫增效组合物具有明显协同增效作用，克服和延缓了害虫抗药性，扩大防治谱，杀虫速度快，明显提高了防治效果。
