Agrochemical residue analysis

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

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.

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

Compounds in BOLD type are not NATA-accredited

NOTE – THPI is only included in analysis of grapes NOT wine.

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.
