The pattern of dissipation and persistence of carbosulfan and its metabolites in banana, cv. Nendran (AAB), with treatments as absolute control (No carbosulfan); recommended dose of per plant application of 400 mg a.i. of carbosulfan, applied in the soil on 0, 60 and 150 days of planting was conducted in red loam soils.The matrix matched samples of different plant parts (leaves, fingers bunches and flower bud, central core of pseudostem and corm) were spiked, and satisfactorily validated for residues extraction QuEChERS method. The plants parts analyzed for residue at predetermined time intervals had residue of carbosulfan in the 1st to 4th leaves till day 20th and subsequent dissipation pattern prediction for BDL in 23.7 day indicated that, at recommended dose of application it is not safe to use the leaves within 23 days of application for serving or food packing (as commonly practiced in every households of Kerala).The residue of carbosulfan and their metabolites were in below detectable limit in blossom bud, flower bract alone, bunch on 15th day of emergence, bunch on 30th day of emergence, peel, bunch (fruit) on harvest, pseudo stem and corm, in recommended dose other additional doses. Metabolites of Carbosulfan residue existed in the 1st, 2nd and 3rdleaves between 5th and 20th day and it dissipated to below detectable limit on 25th day of application.
