不同增效剂对46%氟啶虫酰胺·啶虫脒水分散粒剂防治桃蚜的减量增效作用

Decrement and Synergistic Effect of Different Synergistic Additives in Controling Myzus Persicae with 46%Flonicamid·Acetamiprid WDG

对筛选的7种增效剂配方进行界面性能评价,并探究7种增效剂与46%氟啶虫酰胺·啶虫脒水分散粒剂产品桶混后界面性能及对桃树蚜虫的防效。结果显示:与46%氟啶虫酰胺·啶虫脒水分散粒剂单用相比,桶混时加入增效剂2 000倍稀释液,可显著降低46%氟啶虫酰胺·啶虫脒水分散粒剂使用量25%左右,提高桃树蚜虫防治效果15%以上;助剂中以F-8690及SILWET 625的接触角最小,黏附张力最大,其实际田间应用效果也显著优于其他助剂,具有较好的应用前景和推广价值。

In this paper,the interfacial properties of different synergist formulations was evaluated,and they were used as tank mixture and mixed with 46%Flonicamid·Acetamiprid WDG for controling Myzus persicae.The results showed that compared with the single use of 46%Flonicamid·Acetamiprid WDG,the 2000-fold dilution of the synergistic additives were mixed with 46%Flonicamid·Acetamiprid WDG tank-mix,which could significantly reduce the amount of 46%Flonicamid·Acetamiprid WDG used by about 25%and improve the control effect of Myzus persicae by more than 15%.In addition,F-8690 and SILWET 625 have the smallest contact angle and the largest adhesion tension,their actual field application effect is significantly better than that of other additives,which has good application prospects and promotion value.
