Abstract

It was studied the dissipation rates of fenoxycarb, Lufenuron, flufenoxuron and pyriproxyfen from their application on navelina orange crops to the production of orange juice. Supervised trials were carried out for the phytosanitary treatments under two situations, one according to Good Agricultural Practices (GAP) and the other one with Critical Agricultural Practices (CAP). Samples of both situations were transformed into orange juice according to the current industrial process. The analytical methodology included acetone and dichloromethane/petroleum ether extraction and aminopropyl-based cleanup. Method validation followed SANCO Guidelines. The final objective was the determination of the exposure to the residues in raw and processed orange when good and critical agricultural conditions are used in the field.
