Cauliflower curds plucked from control plants where no pesticidai application had been made were sprayed with 0.005% (50 ppm) alphamethrin and stored at room temperature and refrigerated condition (4 - 5°C). Effect of storage, washing and boiling on dissipation of alphamethrin residue was studied by gas chromatography. Dissipation was relatively faster under room temperature as compared to cold condition. Washing was found to be more effective than cooking. Washing reduced surface residue varying from 7–38% whereas cooking rrduced the eesidue eb y2-17% only.
