Degradation dynamics of bifenthrin in cabbage and soil
摘要
Abstract
Objective] To establish a detection method of bifenthrin ,and to study the residue and degra-dation dynamics of bifenthrin in the form of 1% bifenthrin・ clothianidin granules in cabbage and soil .[Method]Field experiments were conducted in Guangzhou of Guangdong ,Nanning of Guangxi and Qian-jiang of Hubei.Bifenthrin was added at three levels of 0.01,0.10,0.50 mg・ kg -1 in the range from 0.01 to 1.00 mg・ kg -1 .Bifenthrin was extracted from cabbage and soil using ultrasonic-assisted aceto-nitrile extraction ,cleaned up using a florisil solid phase extraction column ,then detected by GC with ECD detector , and quantified by external standard method .[Result]The average recovery rates of bifenthrin in cabbage were 83.64 %-96.44%with 3.26%-7.24%RSD,and the average recovery rates in soil were 86.76%-90.09%with 2.17%-4.94%RSD.The half-life of bifenthrin in soil was 6.77-13.51 d. No bifenthrin residue was detected in cabbage at harvest .[Conclusion]Bifenthrin is an easily degradable pesticide .Using 1%bifenthrin・ clothianidin granules as pesticide is safe and recommended .关键词
