百菌清在猕猴桃和土壤中残留动态

Residual Dynamics of Chlorothalonil in the Soil and Actinidia

摘要:

摘要：建立气相色谱法测定猕猴桃和土壤中百菌清残留的方法，方法的检出限为0.005 mg·kg-1，通过对百菌清在猕猴桃和土壤中降解动态研究，表明百菌清在猕猴桃和土壤中的降解半衰期为5.74 d和7.76 d，施药后第35 d，猕猴桃中百菌清未检出，土壤中百菌清残留量为0.012 mg·kg-1，推荐百菌清在猕猴桃上使用的安全间隔期为35 d。

Abstract:

Abstract:The method was developed for the determination of chlorothalonil residues in Actinidia and soil using Gas Chromatography.The detection limit of chlorothalonil was 0.005 mg·kg-1,the half-life of 5.74 days and 7.76 days in the degradation of chlorothalonil in Actinidia and soil was indicated. After spraying 35 days, the chlorothalonil residues were not detected in Actinidiaand the chlorothalonil residues in soil was 0.012 mg·kg-1. The use of the safety interval of chlorothalonil on the Actinidia is recommaned as 35 days.
