dc.description.abstractResidues of three insecticides i.e diazinon, chlorpyrifos and profenofos that used in Padang Laweh field, West Sumatera for chicory (Brassica peckinensis L) has been analyzed by using Gas Chromatography. Concentration of phosphate was analysed by using UV-Visible spectrophotometric while argentometric Mohr was used to determine the concentration of chloride. Samples were washed using fresh and hot water. Phosphate and chloride concentration was determined in the washing water. The results showed that there was no insecticide residues (diazinon, chlorpyrifos and profenofos) found in samples of two farmers, while the third farmer has been found diazinon insecticide residues in sample without washing (0.0042 mg/Kg). Its value was low than the maximum residue limit (0.05 mg/Kg). The concentration of phosphate was in range of 2.7522 to 9.8165 ppm and from 3.2110 to 22.018 ppm in sample washed using fresh and hot water, respectively. Concentration of chloride was ranged from 0 to 0.2519 ppm and 0.1261 to 0.2519 ppm in samples washed with fresh and hot water, respectively.en_US
