The current study estimated the dissipation rates of abamectin, chlorfenapyr and pyridaben acaricides in pods of green beans (Phaseolus vulgaris L.) under field conditions in Egypt. Pesticides were extracted and cleaned-up by QuEChERS method and were analyzed by HPLC. The dissipation of these acaricides followed the first order kinetics model with half-life (t_1/2) values 1.00, 3.50 and 1.50 days for abamectin, chlorfenapyr and pyridaben, respectively. The lowest residues, at different time intervals of field application rate of each pesticide, were observed with abamectin followed by pyridaben and then chlorfenapyr. Pre-harvest intervals (PHIs) were 10.00, 13.50 and 6.00 days for abamectin, chlorfenapyr and pyridaben, respectively and were below the established European maximum residue limits (EU MRLs) 10–14, 14–21 and 7–10 days after application, respectively. If the fresh pods will be consumed after harvest, it is expected that the presence of these pesticides in the food will have a negative impact on human health. Therefore, the elimination of the residues of these harmful pesticides must be carried out.

目前的研究估计了埃及田间条件下青豆荚（菜豆）中阿维菌素，氯芬那比和哒虫杀螨剂的消散率。通过QuEChERS方法提取和纯化农药，并通过HPLC分析。这些杀螨剂的耗散遵循具有半衰期（t _1/2）分别将阿维菌素，氯芬那比和哒虫灵的值分别设置为1.00、3.50和1.50天。每种农药在田间施用率的不同时间间隔观察到的残留量最低，依次是阿维菌素，吡达本和氯芬那比。阿维菌素，氯芬那比和哒虫苯的收获前间隔（PHIs）分别为10.00、13.50和6.00天，且低于应用后10-14、14-21和7-10天的欧洲最大残留限量（EU MRL），分别。如果收获后将食用新鲜豆荚，则预计食品中这些农药的存在会对人体健康产生负面影响。因此，必须消除这些有害农药的残留。
