Triallate in the product Nufarm Avadex Xtra Selective Herbicide

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application from Nufarm Australia Limited to change the residue definition of triallate to include the metabolite, 2, 3, 3- trichloro-2-propenesulfinic acid (TCPSA). Triallate is the active constituent of a number of products including Nufarm Avadex Xtra Selective Herbicide (APVMA Product Number 56589). No changes in use of Nufarm Avadex Xtra Selective Herbicide, other than to define grazing withholding periods, are proposed in the application. TCPSA is present in commodities treated with triallate at quantifiable levels and the change in residue definition is supported by the APVMA.
