%X A field study to understand dissipation rates and effect of various washing treatments on the residues of seven different insecticides, i.e. tetraniliprole 200 SC, emamectin benzoate 5 SG, lufenuron 5.4 EC, indoxacarb 14.5 SC, thiodicarb 75 WP, profenofos 50 EC and cypermethrin 25 EC in/on cauliflower curd has been conducted. The results showed that initial deposits (just after the last insecticide application, i.e. 0 d) of tetraniliprole, emamectin benzoate, lufenuron, indoxacarb, thiodicarb, profenofos and cypermethrin were 0.43, 0.03, 0.25, 0.28, 0.38, 6.70 and 0.68 mg kg-1, respectively. The dissipation pattern of all the tested insecticides followed monophasic, first order kinetics with the half-lives of 6.25, 8.85, 3.27, 7.71, 4.36, 2.98 and 3.76 d, respectively. Proposed pre-harvest intervals for these insecticides are 6, 9, 3, 8, 4, 3 and 4 d, respectively. All the decontamination techniques showed reductions in residue levels. However, treatment by soaking in 5% sodium bicarbonate aqueous solution showed 54%, 42%, 53%, 48%, 22%, 54% and 77% maximum reductions in residues of tetraniliprole, emamectin benzoate, lufenuron, indoxacarb, profenofos and cypermethrin, respectively, in cauliflower curds. The next best treatment was soaking cauliflower curds in water at 45-50 °C for 10 min, which reduced the residues of cypermethrin, profenofos, tetraniliprole, thiodicarb, emamectin benzoate and lufenuron.
