摘　　要：本文研究了自然条件下氟氰菊酯在苹果和土壤上的消解规律与最终残留量。结果表明，氟氰菊酯在苹果和土壤上消解较为缓慢，苹果上的半衰期为２１．９─２３．６ｄ，土壤上的半衰期为２１．２─２７．８ｄ。在使用浓度为１００─２００ｍｇ／Ｌ，施用２次的情况下，苹果和土壤的最终残留量分别低于０．５和０．０５ｍｇ／ｋｇ。he residue and degradation of Flucythrinate in apple and soil underfield condition were studied,The results showed that the dissipation ofFlucythrinate was slow. Its half-time was 21.9-12.6 days in apple and 21.2-27.8 days in soil,respectively,Apple tree were sprayed twice with Flucy-thrinate at the rate of 100-200mg/L,the residues were less than 0.5mg/kgin apple and 0.05 mg/kg in soil,respectively.
