Australia extended 2,4-D esters suspension

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has extended the period of suspension of the registrations and label approvals of ethyl, butyl and isobutyl esters forms herbicide, 2,4-D (referred to as 2,4-D HVE hereafter). The suspensions are in effect until 31 January 2014.

The APVMA has decided to continue use of, or other dealings with 2,4-D HVE in accordance with current label instructions may be likely to have an unintended effect that is harmful to animals, plants or things or to the environment. In addition, the APVMA has decided that the instructions on currently approved labels for the products may no longer be adequate.

Since 26 September 2006, 2,4-D HVE registrations and associated label approvals have been suspended primarily because of concerns about damage to non-target crops and vegetation from HVE vapour drift. The APVMA has issued instructions for dealing with and using suspended products during the spray window between 1 May and 31 August. Application of 2,4-D HVE only within this spray window would minimise the risk of unintended harmful effects to native vegetation and susceptible crops

During the period of suspension, a person may not possess, have custody of, use or deal with any of the products other than in accordance with the APVMA instructions.
