Study on residual dynamics of SYP-3343 in cucumber and soil

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.
