摘要
对氯虫·噻虫嗪SC(300 g/L)在芥蓝中的残留消解动态进行了研究。结果表明,按照推荐剂量的2倍剂量(60mL/667m2)施药,氯虫苯甲酰胺和噻虫嗪在芥蓝中的原始沉积量分别为3.648 0 mg/kg和8.347 7 mg/kg,残留消解方程分别为Ct=4.198e-0.273 t和Ct=7.589e-0.424 6 t,半衰期分别为2.5 d和1.6 d。施药后21 d氯虫·噻虫嗪残留量降解至0.01 mg/kg以下。
Degrading dynamics of the residue of chlorantraniliprole and thiamethoxam in cabbage mustard were studied in this paper. The results showed that initial residues of chlorantraniliprole and thiamethoxam in cabbage mustard with double recommendatory dose treatment were 3.648 0 mg/kg and 8.347 7 mg/kg respectively, and the dynamics could be described as Ct=4.198e-0.273t and Ct=7.589e-0.4246t with a half-life of 2.5 d and 1.6 d respectively. Residue quantity fell below 0.01 mg/kg after 21 days of pesticide treatment.
