Emamectin benzoate (Proclaim 5 SG) was applied to cabbage at 8.5 and 17 g a.i. ha⁻¹, during the head initiation stage. A high performance liquid chromatography (HPLC) analytical method, for the determination of emamectin benzoate in cabbage, was developed. Average recoveries of emamectin benzoate ranged from 92 % to 96 % at different fortification levels (0.05, 0.25 and 0.50 mg kg⁻¹). The initial deposits, 0.11 and 0.21 mg kg⁻¹ of emamectin benzoate at 8.5 and 17 g a.i. ha⁻¹, dissipated below the determination limit of 0.05 mg kg⁻¹ in 3 and 5 days, respectively.
在甘蓝心形成期，用 8.5 和 17 g a.i./ha 的浓度，分别向甘蓝叶面施甲氨基阿维菌素苯甲酸盐（Proclaim 5 SG）。建立了用高效液相色谱（HPLC）法测定甘蓝中甲氨基阿维菌素苯甲酸盐残留的分析方法。在不同添加水平（0.05、0.25 和 0.50 mg/kg）下，甲氨基阿维菌素苯甲酸盐的平均回收率在 92%至 96%之间。施药后 3 和 5 天，分别以 8.5 和 17 g a.i./ha 的浓度施入的甲氨基阿维菌素苯甲酸盐初始沉积量为 0.11 和 0.21 mg/kg，均低于 0.05 mg/kg 的检测限。
