Residue Dynamics, Waiting Period and Consumer Risk Assessment of Flusilazole on Chilli ( Capsicum annuum L.) in Kashmir by Using Gas Chromatography Tandem Mass Spectrometry

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 ( R 2 ) 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.
