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.

Parathion-methylAtrazine Dimethoate Iprodione Pyrimethanil
Ametoctradin Dimethomorph Malathion Pyriofenone
Azinphos-methyl Emamectin Mandipropamid Quinoxyfen
Azoxystrobin Ethion  Metalaxyl Simazine
Benalaxyl Etoxazole Methamidiphos Spinetoram
Boscalid Fenamiphos Methidathion Spinosad
Buprofezin Fenpyrazamine Methiocarb Spirotetramat
Carbendazim Fenpyroximate Methomyl Spiroxamine
Chlorantraniliprole Fenarimol Myclobutinal Sulfoxaflor
Chlorpyrifos Fenhexamid Oxadixyl Tebuconazole
 Chlorpyrifos-methyl Fenitrothion Parathion-methyl Tebufenozide
 Clothianidin Fenthion Penconazole Tetraconazole
Cyflufenamid Fludioxonil Procymidone THPI (see below)
Cyproconazole Flusilazole Propiconazole Triadimefon
Cyprodinil Hexaconazole Proquinazid Triadimenol
Diazinon Indoxacarb Prothiofos Trichlorfon
Difenoconazole Iodocarb Pyraclostrobin Trifloxystrobin

Compounds in BOLD type are not NATA-accredited

NOTE – THPI is only included in LCMS-02 NOT in LCMS-01.

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.
