纳米18%阿维.烟碱AS对菜粉蝶幼虫毒力测定结果:比单剂1.8%阿维菌素EC和40%硫酸烟碱EC的毒力都高,得出了毒力回归方程式,共毒系数值大于常数值100,表明纳米18%阿维.烟碱AS具有较强的增效作用;配伍纳米18%阿维.烟碱AS在室内测出了对菜粉蝶效力最强的最佳使用剂量梯度(每公顷用药量),研究表明:用375~750 mL/hm2,有效成份a.i.g/hm2(67.5~135 g)对水750 L,对菜粉蝶的防效高、速效性和持效性强。
Nano 18% Avi Nicotine AS on cabbage butterfly larvae virulence determination results: a single dose of 1.8% avermectin EC and 40% nicotine sulfate nicotine EC are virulent, obtained virulence regression equation, a total of Poison coefficient value is greater than the constant value of 100, indicating that the nano-18% Avi Nicotine AS has a strong synergistic effect; Compatibility nano 18% Avi Nicotine AS in the laboratory measured the most effective cabbage butterfly best Using the dose gradient (dosage per hectare), the results showed that the control effect of 750 L of water at 750 ~ 750 mL / hm2 and active ingredient aig / hm2 (67.5 ~ 135 g) on cabbage butterfly was effective, fast and effective Strong.
