Abstract The effect of the pesticide dose used to control pests in olive trees and the date of treatment on the residues present in the oil were studied for four organophosphorus pesticides (diazinon, malathion, trichlorphon and chlorfenvinphos) and one organochlorine (endosulfan). Pesticide residue analysis was performed using online reversed‐phase liquid chromatography–gas chromatography, using an automated through oven transfer adsorption desorption interface and selective detectors, such as nitrogen–phosphorus detector and electronic capture detector. A simple filtration step was necessary before the chromatographic analysis of samples. The obtained data were statistically analyzed and conclusions about olive pesticide treatments are presented.
