摘　　要：采用田间试验方法研究了唑菌酯在黄瓜和土壤中的残留与降解情况。采用液相色谱法-二级管阵列紫外检测器测定了唑菌酯在黄瓜和土壤中的残留量,结果表明,唑菌酯的降解符合一级动力学方程,在黄瓜和土壤中的半衰期分别为2.0～2.2d、2.6～2.7d,在正常使用条件下,不会造成黄瓜残毒污染和土壤的残留积累。A field experiment was conducted to research the dynamics of SYP-3343 in cucumber and soil. Analytical method of SYP-3343 in cucumber and soil by HPLC with PAD detector had been established. The decline rules followed the first-order kinetic equation, and its half-lives was 2.0～2.2 days in cucumber and 2.6～2.7 days in soil, respectively. The final residues of SYP-3343 in cucumber and soil were lower than 0.5 mg/kg.
