几种植物源增效剂对46%氟啶虫酰胺·啶虫脒WG防治辣椒蚜虫的减量增效研究

Decrement and synergistic effect of plant-derived synergists in controling aphids on pepper plants with flonicamid·acetamiprid 46% WG

[目的]为46%氟啶虫酰胺·啶虫脒WG田间应用提供指导和思路。[方法]选取4种不同类型的植物源桶混增效剂,评价其界面性能,并稀释至质量浓度500.00 mg/L与46%氟啶虫酰胺·啶虫脒WG药液有效成分质量浓度65.71 mg/L桶混应用于辣椒蚜虫防治。[结果]通过界面性能评价和田间药效试验,证明了添加桶混助剂后,可降低46%氟啶虫酰胺·啶虫脒WG使用量至少25%,提高辣椒蚜虫防治效果25%以上。[结论]添加桶混助剂可以促进农药最大程度地发挥生物活性,其可有效调控药剂的剂量传输效率,为农药减施增效提供了一种方法。

[Aims] Providing guidance and ideas for flonicamid·acetamiprid 46% WG in field applications.[Methods] 4 Different types of plant-derived synergists were selected,whose interface properties were evaluated,diluted to 500 mg/L,and mixed with flonicamid·acetamiprid 46% WG at 65.71 mg/L to control aphids on pepper plants.[Results] Through the evaluation of interfacial properties and control effect,it was proved that adding tank-mixed adjuvants could significantly reduce the amount of flonicamid·acetamiprid 46% WG by about 25% and improve the control effect against aphids on pepper plants by more than 25%.[Conclusions] Adding tank-mix adjuvants,which could effectively regulate the dose delivery efficiency of pesticides,can promote the biological activity of pesticides to the most extent,providing a method for reducing pesticide application and increasing efficiency.
