Dissipation of tetraniliprole and its metabolite, chinazolinon in tomato was studied. Immature fruit samples were collected at specific intervals with three applications. Modified QuEChERS method was used and satisfactory recovery of 78.28 to 104.77 % was obtained. Good linearity (0.05 to 1.00 μg g-1) with coefficient of determination (R2) > 0.99 was recorded. The initial deposit at 60 (x) and 120 g a.i. ha-1 (2x) was 0.42 and 0.65 μg g-1 and reached the below limit of quantification on 5th and 7th days after spraying. The half-life period was 1.3 and 1.6 days and the safe waiting period was 4.5 and 5.8 days at x and 2x doses, respectively. The harvest time (20th day) samples, mature fruit and soil were at BLQ in both the doses. The metabolite, chinazolinon was not detected in any of the sample analyzed. Theoretical maximum residue contribution (TMRC) was less than maximum permissible intake even on the day of spraying.
