The present study was designed to determine the extent of reduction in pesticide residues from chilli fruits by following different decontamination processes. Samples were collected from the field at 0 and 1 days after application of indoxacarb 14.5 SC at 55 and 110 g ai ha^-1 (foliar application) and thiamethoxam 30 FS at 2.1 and 4.2 g ai ha^-1 (seed treatment). The sample was subjected to different household processes like sun-drying, tap-water wash, boiling, soaking in different salt solutions for 10 min alone and soaking along with tap-water wash. Residues from chilli fruit samples were extracted using QuEChERS method and analysed on GLC and GC-MS/MS. Among all treatments, soaking in 4% acetic acid along with tap-water wash removed 70.7-74.7% residues, followed by 0.1% baking soda (61.2-74.9%). However, boiling proved the most effective process (78.8%). In addition, sun-drying of red chilli increased residues by 1.5-2.5 folds.
