| Abstract: | A determination method of pyrimethanil in cucumber and soil was established. The recovery rates and of this method ranged 81.5 % - 99.3 %, the CVs were 1.4 % - 5.3 %. The regressive equations of pyrimethanil in cucumber and soil were Ct = 0. 9947e^-0.1356t and Ct = 0. 7368e^-0.1783t, respectively. The correlation coefficient of pyrimethanil in cucumber and soil were 0.9552 and 0.9496, respectively.The half-life of pyrimethanil in cucumber and soil were 5.11 and 3.89 days, respectively. |
