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.
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]).
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:
|Azinphos methyl||Fenarimol||Parathion methyl|
|Dicofol (both isomers)||Metalaxyl||Tebuconazole|
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.
