Abstract:

Experiments of field and laboratory were carried out to evaluate the effect of different decontamination processes on reduction of chlorpyrifos and cypermethrin residues in cauliflower curds like washing, cooking, washing plus cooking and dipping in chemical solutions after application of ready-mix formulation Cannon 55EC (chlorpyrifos 50% + cypermethrin 5%) on the crop. Ready-mix formulation Cannon 55EC was applied twice at the rate of 1ml/L at 15 days interval on cauliflower crop. Cauliflower curds were collected at 0 (2 hours), 3 and 7 days interval after the last spray and subjected to decontamination processes. Washing of zero day contaminated curd samples provided 37.41% relief from chlorpyrifos residues and 40.10% relief from cypermethrin residues. Cooking degraded chlorpyrifos residues up to 36.58-58.95% and cypermethrin residues by 45.45-66.31%. Washing plus cooking removed chlorpyrifos and cypermethrin residues up to 70% as compared to other processes and proved to be the best technique in removing the residues. Washing of curds with 2% NaOH solution reduced the chlorpyrifos residues up to 60.97-69.03%, whereas washing with 0.05% solution of HCl reduced the chlorpyrifos residues up to 58.53-65.06%. Similarly cypermethrin residues were reduced to 62.50-69.20% after treatment with 2% NaOH solution and up to 63.44-66.97% after treatment with 0.05% HCl solution.
