| Popis: | Dissipation and decontamination of chlorantraniliprole (Coragen 18.5 SC) in brinjal and okra fruits were studied following field application at single and double doses of 30 and 60 g ai ha(-1), and the residues of the insecticide was estimated using LC-MS/MS. Initial residues of chlorantraniliprole at single and double doses on the fruits of brinjal were 0.72 and 1.48 mg kg(-1), while on okra fruits, the residues were 0.48 and 0.91 mg kg(-1), respectively. The residues reached below detectable level of 0.01 mg kg(-1) on the 10th day. Half-life of chlorantraniliprole at 30 and 60 g ai ha(-1) on brinjal was 1.58 and 1.80 days with the calculated waiting period of 0.69 and 2.38 days, whereas on okra, the values were 1.60 and 1.70 and 0 and 1.20 days, respectively. The extent of removal of chlorantraniliprole using simple decontaminating techniques at 2 h and 3 days after spraying was 40.99-91.37% and 29.85-89.12%, respectively, from brinjal fruits and 47.78-86.10% and 41.77-86.48%, respectively, from okra fruits. |
