Agrochemical residue analysis

Multi residue assay (GCMS)

The Analytical Service provides 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. The analysis of wine and juice is accredited by the National Association of Testing Authorities (NATA) and is regularly exposed to international proficiency testing. Wherever possible, residues are analysed as per their maximum residue limit (MRL) definition.

An analytical method employing extraction, cleanup and gas chromatography/mass spectrometry (GC-MS) operating in selected ion monitoring mode has been developed for accurately determining the concentration of all of these compounds. The analysis can be used for any of the following matrices: grapes, wines, *leaves, juices, marc, *soil, water, *winery and vineyard effluent.

*Please call us if you would like these sample types analysed.

Multi residue assay (HPLC)

High pressure liquid chromatography (HPLC) with diode array detection is used for the determination of a number of residues not included in the MRA. These include Pyrimethanil, Fluidioxonil, Cyprodonil, Fenhexamid and Tebufenozide. This method is also NATA accredited for grapes, juice, wine and marc, and is exposed to international proficiency testing.

Strobilurins

The strobilurin analysis includes the recently registered azoxystrobin (both isomers), trifloxystrobin, pyraclostrobin and boscalid.

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

The GCMS-MRA is currently being validated for tetraconazole and buprafezin, which have recently been registered for viticultural use.
