Fosetyl aluminum dosage

Fosetyl aluminium (CAS No. 39148-24-8) is a systemic fungicide widely used in agriculture to protect crops against fungal diseases such as downy mildew. It works by stimulating the plants' natural defenses and inhibiting the growth of pathogenic fungi.

Fosetyl-Al analysis allows for the precise quantification of residues present in fruits, vegetables, cereals, wines, and other plant products . This analysis is essential to verify regulatory compliance and ensure adherence to the maximum residue limits (MRLs) set by Regulation (EC) No 396/2005 on pesticides in foodstuffs.

Analytical method: LC-MS/MS

Fosetyl aluminum is analyzed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) .
This reference technique allows for:

• Specific and ultra-sensitive detection of fosetyl and its metabolites (including phosphonate);
• quantification at very low thresholds (μg/kg);
• identification in complex matrices such as juices, wines or plant extracts.

The protocols applied by the partner laboratories comply with European and international standards (ISO, AOAC) and guarantee the traceability and reproducibility of the results.

Industrial and regulatory applications

Fosetyl aluminium assay is relevant to several sectors:

• Food processing industry : quality control of finished products and verification of regulatory compliance.
• Plant and wine sectors : monitoring of residues in fruits, vegetables, cereals, wines and extracts.
• Organic and natural production : detection of possible cross-contamination or non-compliant residues.
• R&D and control laboratories : monitoring of phytosanitary treatments and stability studies.

This analysis can be combined with the measurement of multi-residue pesticides or the determination of phosphonates for a complete monitoring of plant protection residues.

Affected matrices

YesWeLab's partner laboratories perform fosetyl aluminium assays on various matrices:

• Fresh fruits and vegetables
• Cereals and derived products
• Wines, musts and vegetable juices
• Processed products and nutraceutical extracts

Each method is adapted to the nature of the matrix and the level of sensitivity required in order to obtain reliable results that comply with regulatory requirements.
