The objective of this experiment was not only to provide a simple residue analytical method to evaluate the safe application rate of Emamectin Benzoate for paddy crops but also to give a suitable recommended dosage in paddy crops. Paddy samples were detected using HPLC-MS/MS. The half-lives of emamectin benzoate in paddy plants, water and soil were 2.04-8.66 days, 2.89-4.95 days and 3.65-5.78 days with a dissipation rate of 90% over 7 days after application, respectively. Low residues and short half-life suggested that Emamectin Benzoate could be safely used in paddy crops with the suitable dosage and application.
本实验的目的不仅在于提供一种简单的残留分析方法来评估甲氨基阿维菌素苯甲酸盐在稻田作物中的安全使用剂量，还在于给出稻田作物中的适宜推荐剂量。采用高效液相色谱-串联质谱法检测稻田样品。甲氨基阿维菌素苯甲酸盐在水稻植株、水和土壤中的半衰期分别为 2.04-8.66 天、2.89-4.95 天和 3.65-5.78 天，施药 7 天后消解率达到 90%。低残留和短半衰期表明，甲氨基阿维菌素苯甲酸盐在稻田作物中可以安全使用，适宜的剂量和施药方式是关键。
