A study on the leach­ing of chlor­pyri­fos in an oil palm agro ecosys­tem was con­ducted in an oil palm plan­ta­tion in Sep­ang, Selan­gor. The insec­ti­cide chlor­pyri­fos was sprayed using a knap­sack sprayer at the rec­om­mended and dou­ble the rec­om­mended dosage. Soil sam­ples were col­lected at dif­fer­ent depths, viz. 0–10 cm, 10–20 cm, 20–30 cm, 30–40 cm and 40–50 cm at the fol­low­ing inter vals: –1 day (before treat­ment), 0 day (day of treat­ment, 6 hr later), 1 day, 3, 7, 14, 30 and 60 days after treat­ment. Recov­ery of chlor­pyri­fos from the soil spiked with chlor­pyri­fos at 4–50 μg kg–1 ranged from 88%-99% with the coef­fi­cients of vari­a­tion r anging from 2.0% to 7.5%. Chlor­pyri­fos residue was detected at 0–10 cm and 10–20 cm depths when applied at the rec­om­mended and dou­ble the rec­om­mended dosages, respec­tively. The residue was only detected in the soil for up to five and seven days after treat­ment, respec­tively, when applied at the rec­om­mended and dou­ble the rec­om­mended dosages.
