甲基硫菌灵在苹果和土壤中的消解动态和最终残留研究
Degradation Dynamics and Final Residues of Thiophanate-methyl in Apple and Soil
摘要
Abstract
The degradation dynamics and final residues of thiophanate-methyl wettable powder in apples and soils of 3 different areas (Yantai, Tianjin, Suzhou) from 2011 to 2012 were studied by HPLC-VWD. The results showed that the degradation dynamics of thiophanate-methyl including carbendazol conformed to the first-order kinetic reaction equation. The degradation half-lives were 7. 3 ～ 13. 2 d and 4. 4 ～ 7. 1 day in apples and soils respectively. After 30 days from the last application, the final residual quantities of thiophanate-methyl including carbendazol were ranged from below 0. 05 mg /kg to 2. 49 mg /kg, which were lower than 3. 0 mg /kg prescribed by CAC. The study indicated that the application of 70％ thiophanate-methyl wettable powder at the doses of 875 ～ 1 312. 5 mg a. i /kg for 3 ～ 4 times was safe to apple and soil.关键词
