Agrochemical residue analysis

The analysis of wine, juice and grapes by GC/MS and LC/MS/MS is accredited by the National Association of Testing Authorities (NATA) and is regularly exposed to international proficiency testing via the FAPAS program.

Multi-residue analysis – LC/MS/MS

This multi-residue assay covers a broad range of fungicides and insecticides, targeting those agrochemicals which are currently registered, or recently deregistered, for viticultural use in the Australian wine industry. The analysis is available for grapes, juice and wine and utilises the well-published QuEChERS extraction technique combined with the greater specificity of liquid chromatography with tandem mass spectrometry (LC/MS/MS). The list of compounds determined in this assay is outlined below.

Atrazine Dimethomorph Methoxyfenozide Tetraconazole
Azinphos-methyl Ethion Myclobutinal Triadimefon
Azoxystrobin Fenarimol Oxadixyl Triadimenol
Benalaxyl Fenhexamid Parathion-methyl Trifloxystrobin
Boscalid Fenitrothion Penconazole
Buprofezin Fenthion Procymidone
Captan Fludioxonil Propiconazole
Carbaryl Flusilazole Pyraclostrobin
Carbendazim Hexaconazole Pyrimethanil
Chlorpyrifos Indoxacarb Quinoxyfen
Chlorpyrifos-methyl Iprodione Simazine
Cyprodinil Malathion Spiroxamine
Diazinon Metalaxyl Tebuconazole
Dimethoate Methidathion Tebufenozide

All compounds are analysed to a limit of quantitation (LoQ) of 0.01 mg/kg[L] (except captan and fludioxonil which are 0.02 mg/kg[L]).

Multi-residue assay (GCMS)

We provide a fast and reliable agrochemical residue analysis service to the Australian wine industry. The routine scan includes 33 residues, which include over 50 brand name agrochemicals. Wherever possible, residues are analysed as per their maximum residue limit (MRL) definition.

The analytical method employs extraction, cleanup and gas chromatography/mass spectrometry (GC/MS) operating in selected ion monitoring mode.

Agrochemical residues included in the assay:

Atrazine Ethion Oxadixyl
Azinphos methyl Fenarimol Parathion methyl
Benalaxyl Fenitrothion Penconazole
Captan Fenthion Procymidone
Carbaryl Flusilazole Propiconazole
Chlorothalonil Hexaconazole Prothiophos
Chlorpyrifos Holoxacarb Quinoxyfen
Chlorpyrifos methyl Iprodione Simazine
Diazinon Malathion Spiroxamine
Dicofol (both isomers) Metalaxyl Tebuconazole
Dimethoate Methidathion Triadimefon
Dimethomorph Myclobutinal Triadimenol
Vinclozolin

We also have validated methods for Emamectin, Fluazinam and Spinosad. Please contact us if you require these analyses.

For information regarding agrochemicals for use in the wine industry or maximum residue limits for export destinations, please visit the agrochemicals web site or download the AWRI publication, Agrochemicals registered for use in Australian viticulture.

Teamed with the AWRI’s knowledge of maximum residue limits (MRLs) and impacts on winemaking, we are able to advise wineries and growers on an appropriate course of action for the handling of samples with positive results.
