摘　　要：为评价联苯菊酯在小麦上使用的安全性,开展联苯菊酯在小麦和土壤中的残留试验研究。田间试验结果表明,联苯菊酯在小麦植株和土壤中的消解行为均符合一级降解动力学方程,其消解半衰期分别为6.4~15.3 d、12.3~18.0 d。收获期小麦植株、小麦籽粒和土壤中联苯菊酯残留量分别为0.042~1.226 mg/kg、小于0.010~0.022 mg/kg、小于0.010~0.053 mg/kg。In order to evaluate the safety of bifenthrin in wheat,the residues of bifenthrin in wheat and soil were studied.Field experiments were conducted in three different locations during two years.The results showed that the degradation behaviors of bifenthrin in wheat plants and soils met the first-order kinetics equation with the half-lives of 6.4-15.3 days and 12.3-18.0 days,respectively.The final residues of bifenthrin in plant,wheat seeds,and soils were 0.042-1.226 mg/kg,less than 0.010-0.022 mg/kg,less than 0.010-0.053 mg/kg.
