    Insecticide residues with the active compounds of diazinon, chlorpyrifos and profenofos on green mustard from Padang Laweh, West Sumatra were obtained from nine samples. One farmer used diazinon(0.0064 mg/kg) while the other farmer used profenopos(0.3947 mg/kg) which was detected from their samples without any treatment. Washing samples using normal water and hot water was able to decreased pesticide residues level on mustard greens. Diazinon level could be deacrease for 25% while profenopos was not detected after washing. The concentration of phosphate and chloride in washing waterwas ranged from 0.577 to 0.8256 ppm and from 0 to 0.623 ppm for normal water, while in hot water was ranged from 1.467 to 2.477 ppm and from 2.52 to 4.413 ppm respectively.
