Abstract

Chlorantraniliprole is quite effective in management of fruit borer in tomato and approved for use in India. The continuous use of pesticides for protecting insect pests may further aggravate the problem of pesticide residues. The methodology for estimation of its residues is required. For this QuEChERS techniques with slight modification have been standardised in this study. The approach may be employed for quantitative analyte assessment in a variety of agricultural products whilst still minimising the usage of organic solvents, allowing the methodology to gain greater acceptance. The motto of this present study is to standardize and validate the QuEChERS method for the assessment of chlorantraniliprole residues in tomato. Aliquots of tomato samples were analyzed by using UHPLC- PDA with a C18 column. “Retention time” was observed to be 4.327 min. Mean recoveries of chlorantraniliprole in tomato samples spiked 0.5, 0.25 and 0.05 mg kg-1 varied about 85.33 to 87.60 per cent. LOQ

Conclusion

QuEChERS method was standardized and validated with slight modifications by following SANCO guidelines for assessment of chlorantraniliprole in tomato. Mean recoveries were found to be greater than 80 per cent. RSDr for chlorantraniliprole in tomato at 0.05-0.25 mg kg-1 was 2.949 to 7.306 per cent. RSDR of chlorantraniliprole at 0.05 mg kg-1 was 4.671 per cent.
