Pesticide Residue Analysis

AWTA Ltd provides a Chemical Residue Testing service for greasy and semi-processed wool which identifies and quantifies the residual level of chemicals remaining from lice, fly and ectoparasite treatments.  Concentrations of individual chemicals are reported and summarised as total concentrations of Organophosphates, Organochlorines, Synthetic Pyrethroids, and the Insect Growth Regulators (Diflubenzuron, Triflumuron & Dicyclanil) in accordance with the international standard IWTO DTM59-04.  The report also indicates if the residual concentrations comply with current Eco-Labelling standards for wool exports into the European Union.

The service can be requested when bales are cored, or after yield and micron measurement is complete. Testing can be conducted on single sale lots or composite samples blended from multiple sale lots (up to 10).   Wool is taken from sample material that remains after core testing at one of our Raw Wool Laboratories and sent to our Agrifood Technology division for analysis.  The turnaround time is 5 days from the receipt of sample or test request, with completed tests issued as AWTA Ltd Guidance Test Reports.

An example of a Residue Test Report for a single sale lot is shown below.
