摘　　要：研究和建立了3种不同剂型甲氨基阿维菌素苯甲酸盐从土壤中提取的方法和液相色谱检测方法,并比较了它们在土壤中的消解动态。结果表明,3种剂型甲维盐的提取条件存在一定差异,但甲维盐HPLC-UV检测条件一致。降解动态试验结果表明,3种剂型甲维盐降解动态均符合一级反应动力学方程Ct=C0e-kt,甲维盐颗粒剂、微囊悬浮剂和乳油半衰期分别为71.46～123.78、45.90～59.24d和28.88～37.67d。剂型对甲维盐降解动态存在显著影响。An analytical method was experimented for testing three kinds of preparations of emamectin benzoate and compared the insecticide degradation trends in soils.The results showed that there were some differences in the extraction conditions,but no difference in the HPLC-UV detection conditions to the test pestiside and the degradation of three emamectin benzoate preparations in soil could be described with equation of Ct =C0e-kt.The degadate half-life of emamectin benzoate turned in different formulation was estimated to be 71.46～123.78 d for granules,45.90～59.24 d for microcapsule suspension and 28.88～37.67 d for emulsifiable concentrate in soil,respectively.The formulations of emamectin benzoate significantly affect the degradation.
