| Abstract | ||
| Dissipation kinetics and transformation pathways of cyantraniliprole, as a new diamide class of insecticide, are very important, since the degradation products exhibited toxicological effects and may cause more environmental hazards than the parent product. The present study was carried out to explore the fate of cyantraniliprole in tomato plants and soil under open field conditions. The determination of residues was set on HPLC Diode-Array Detection and identification of degradation products by LCMS single quadrupole mass. The dissipation rate of cyantraniliprole was ascribed to first‐order kinetics, where the rate of disappearance in tomato fruits was faster than in leaves and soil with half-lives determined to be 1.63, 5.25 and 5.92 days in tomatoes fruits, leaves and soil, respectively. The results showed that cyantraniliprole transformed into many degradation products and can be identified about 9 products. IN-J9Z38 which consider the major metabolite detected in all compartments. The detection of other degradation products varied within tomato fruits, leaves and soil. These results will help in management and establish the best scenario to minimize the adverse effects of residues and involved in risk assessment study. | ||
