Pyriproxyfen concentration determination

Pyriproxyfen is a growth-regulating insecticide (GRI) from the pyridylether family, used primarily to control insect populations by disrupting their life cycle. It is commonly used in crop protection, household hygiene, and in pest control products (whiteflies, mosquitoes, etc.).

Its measurement is essential for verifying residue levels in food, plant, or environmental matrices. It also allows for validating the compliance of plant protection product or biocidal formulations with European and international regulations (e.g., EC Regulation 396/2005, REACH, BPR).

Dosage objectives

• Control the active ingredient content in insecticide formulations
• Monitor residues in plant-based or animal-based foodstuffs
• Check that the maximum residue limits (MRLs) have not been exceeded
• Assess environmental contamination (water, soil, treated surfaces)
• Meeting regulatory requirements for export, labeling, or certification

Analytical methods

Pyriproxyfen analysis is performed by high-performance liquid chromatography (HPLC) or liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). These methods guarantee specific, sensitive, and reproducible quantification, even at trace levels.

The method is particularly suited to complex matrices or matrices with low residue content.

Analyzed matrices

• Technical plant protection product formulations (liquids, powders, granules)
• Residues on fruits, vegetables, and aromatic plants
• Plant or animal food supplements
• Runoff water, wash water or wastewater
• Soils, substrates, treated agricultural or industrial surfaces

Regulatory compliance

The dosage of pyriproxyfen is subject to strict regulatory guidelines:

• Control of food MRLs (Regulation EC 396/2005)
• Evaluation of active substances for REACH registration
• Monitoring of effluents or environmental discharges
• Registration dossiers for plant protection products or biocides (BPR)
