Enantioselective degradation of tebuconazole in cabbage, cucumber, and soils
2012
The enantioselective degradation of tebuconazole has been investigated to elucidate the behaviors in agricultural soils, cabbage, and cucumber fruit. Rac-tebuconazole was fortified into three types of agricultural soils and sprayed foliage of cabbage and cucumber, respectively. The degradation kinetics, enantiomer fraction and enantiomeric selectivity were determined by reverse-phase high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) on a Lux amylose-2 chiral column. The process of the degradation of tebuconazole enantiomers followed first-order kinetic in the test soils and vegetables. It has been shown that the degradation of tebuconazole was enantioselective. The results indicated that the (+)-S-tebuconazole showed a faster degradation in cabbage, while the (−)-R-tebuconazole dissipated faster than (+)-S-form in cucumber fruit and the test soils.
