The fate of benfuracarb was studied under field conditions in brinjal fruits and soil following foliar spray application at 0.25 and 0.50 microg g(-1) by HPLC. At 0.25 microg g(-1), benfuracarb persisted up to 7 days both in soil and brinjal but at 0.50 microg g(-1), benfuracarb residues persisted up to 10 and 12 days in soil and brinjal fruits, respectively. The persistence of benfuracarb residues, both in soil and brinjal, followed first-order kinetics. The half-life values of benfuracarb in soil and brinjal fruit were found to be 3.54 and 3.90 days at 0.25 microg g(-1) and 3.75 and 4.73 days at 0.50 microg g(-1), respectively.
通过高效液相色谱法（HPLC），在田间条件下研究了在茄子果实和土壤中，以0.25和0.50微克/克（-1）的剂量进行叶面喷施后，丙硫克百威的残留情况。在0.25微克/克（-1）的剂量下，丙硫克百威在土壤和茄子中均可残留长达7天；但在0.50微克/克（-1）的剂量下，丙硫克百威在土壤和茄子果实中的残留时间分别长达10天和12天。丙硫克百威在土壤和茄子中的残留均遵循一级动力学。在0.25微克/克（-1）的剂量下，丙硫克百威在土壤和茄子果实中的半衰期分别为3.54天和3.90天；在0.50微克/克（-1）的剂量下，半衰期分别为3.75天和4.73天。
