噻霉酮在烟草上的残留与消解动态
|
摘要
为噻霉酮在烟草病害防治上安全使用和推广提供科学依据,采用田间试验研究3%噻霉酮水分散粒剂在烟草上的消解动态和最终残留。结果表明:噻霉酮在烟草中的消解动态符合一级动力学方程,其消解半衰期为2.8～3.1d,最终残留量均小于最低检测浓度0.5mg/kg。噻霉酮在烟草中的消解速率较快,用于防治烟草病害安全。
To provide a scientific basis for the safe application and promotion of benziothiazolinone in tobacco disease control,a field experiment was conducted to study the digestion dynamics and final residue of 3% benziothiazolinone water-dispersible granules on tobacco. Results: Digestion dynamics of benziothiazolinone on tobacco accorded with the first-order kinetic equation,and the half-life of digestion was 2.8-3.1 d.The final residual amount was less than the minimum detection concentration of 0.5 mg/kg.The digestion rate of benziothiazolinone on tobacco is fast and it is used to control tobacco diseases.
