Residue Dynamics, Waiting Period and Consumer Risk Assessment of Flusilazole on Chilli (Capsicum annuum L.) in...

The present investigation was carried out to study the "Residue Dynamics of Flusilazole on Chilli (Capsicum annuum L.) fruits in Kashmir." Flusilazole 40 EC at the recommended dosage (0.02%) and double the recommended dosage (0.04%) were applied on chilli. The sampling was done on 0, 1, 3, 5, 7, 10, 15, 20, 25, and 30 days after application. Flusilazole was analyzed by GC-MS/MS. The linearity for flusilazole was achieved, with the determination coefficients (R²) of 0.998. The recovery percentage of flusilazole was found to be within the acceptable range of 70%-120%. The dissipation of flusilazole on chilli fruit at the recommended dose (0.02%) left an initial deposit of 1.713 ± 0.004 ppm, which dissipated by 99.35% in 15 days and was below LOQ (0.02 mg kg^-1) beyond this period. The half-life period (t_½) and Pre-Harvest Interval (PHI) (T_tol) of 1.55 days and 15.19 days were recorded. Flusilazole at double the recommended dose (0.04%) left an initial deposit of 2.634 ± 0.004 ppm, which dissipated by 99.46% in 25 days and was below LOQ (0.02 mg kg^-1) beyond this period. The half-life period (t_½) and PHI (T_tol) of 3.01 days and 19.83 days were recorded.
