Dissipation of two insecticide mixtures namely indoxacarb 14.5 per cent + acetamiprid 7.7 per cent SC and chlorantraniliprole 9.3 per cent + lambda-cyhalothrin 4.6 per cent ZC, applied at 111 and 35 g a.i. ha−1 respectively at the time of fruit set, is reported. An initial deposit 1.04 μg g−1 of indoxacarb was recorded at 0 d (2 h after application) and this gradually declined and reached below its determination limit of 0.01 μg g−1 on the 10th d. The dissipation pattern of indoxacarb followed bi-phasic mode with half-life of 3.14 d in phase I (0–3 d) and 0.95 d in phase II (3–7 d). The initial deposit of acetamiprid was 0.01 μg g−1 which degraded very fast and reached below determination level (BDL) within 24 h. The initial deposit 0.08 μg g−1 of chlorantraniliprole was recorded at 0 d (2 h after application) and reached below its determination limit on 10th d with a half-life value of 3.85 d. Similarly, the initial deposit of lambda-cyhalothrin was 0.06 μg g−1 which declined to 0.03 μg g-1 on 1st d and on the 3rd d, it reached below the determination level of 0.01 μg g−1 with a half-life value of 0.83 d.
