In undertaking this task, the APVMA works in close cooperation with advisory agencies, including the Department of Health and Ageing, Department of Environment and Energy, Department of Agriculture and Water Resources, and State Departments of Primary Industries. The APVMA has a policy of encouraging openness and transparency in its activities and of seeking community involvement in decision making. Part of that process is the publication of public release summaries for products containing new active constituents. The information and technical data required by the APVMA to assess the safety of new chemical products, and the methods of assessment, must be consistent with accepted scientific principles and processes. Details are outlined in the APVMA’s application requirements and data guidelines. This public release summary is intended as a brief overview of the assessment that has been conducted by the APVMA and of the specialist advice received from its advisory agencies. It has been deliberately presented in a manner that is likely to be informative to the widest possible audience thereby encouraging public comment. About this document This is a public release summary. It indicates that the Australian Pesticides and Veterinary Medicines Authority (APVMA) is considering an application for registration of an agricultural or veterinary chemical. It provides a summary of the APVMA’s assessment, which may include details of: • the toxicology of both the active constituent and product • the residues and trade assessment • occupational exposure aspects • environmental fate, toxicity, potential exposure and hazard • efficacy and target crop or animal safety. Comment is sought from interested stakeholders on the information contained within this document. vi PUBLIC RELEASE SUMMARY—TALINOR HERBICIDE Making a submission In accordance with section 13 of the Agvet Code, the APVMA invites any person to submit a relevant written submission as to whether Talinor Herbicide should be registered.

INTRODUCTION 1 1 INTRODUCTION 1.1 Applicant Syngenta Australia Pty Ltd 1.2 Purpose of application Syngenta Australia Pty Ltd has applied to the APVMA for registration of the new product Talinor Herbicide containing 175 g/L bromoxynil present as the octanoate, 37.5 g/L bicyclopyrone and 9.4 g/L cloquintocet- mexyl in an emulsifiable concentrate (EC) formulation. This publication provides a summary of the information reviewed and an outline of the regulatory considerations for the proposed registration of Talinor Herbicide, containing the new active constituent bicyclopyrone. Bromoxynil present as the octanoate (herbicide) and cloquintocet-mexyl (crop safener) are APVMA approved active constituents which are present in other APVMA registered products. Bicyclopyrone was assessed under a Global Joint Review (GJR) workshare arrangement where applications were submitted and considered concurrently in Australia, Canada and USA. The product Talinor Herbicide has been considered separately from the GJR workshare and is new to the Australian market. The active bicyclopyrone as well as the end-use product will be manufactured overseas and imported into Australia. 1.3 Product claims and use pattern Talinor Herbicide is a selective herbicide. The proposed use pattern is as a foliar spray applied in a tank mix with the registered Adigor Spray Adjuvant (60114) for the early post-emergent control and suppression of broadleaf weeds in wheat (except durum wheat) and barley (between wheat and barley crop stages GS12 and GS32).
