2,4-D forms and permits
- New Instructions on using 2,4-D HVE
- 2,4-D Recordkeeping form (Spray Record)
- Background and criteria for permits during the suspension period and Permit form for 2007/2008 season
The review of 2,4-D has been split into two parts:
- Part 1: contains the environmental risk assessment of high volatile 2,4-D (short-chain) esters
- Part 2: contains the toxicological, occupational health and safety assessments and the environmental risk assessment of the low and non-volatile forms (acid, salt, and long-chain esters) of 2,4-D.
Currently only the Preliminary Review Findings (PRF) report for Part 1 is available. A report for Part 2 will be released after the initial assessments are completed.
2, 4-D review
Status: review in progress
In 1995 the APVMA began a review of 2,4-D because concerns over its potential risk to public health, occupational health and safety, and the environment (including impacts on waterways, non-target animals and plants).
In April 2006 the APVMA released the 2,4-D Preliminary Review Findings Report (Environment) Part One: 2,4-D HVE Esters. The APVMA found that short-chain ester (ethyl ester, butyl ester and isobutyl ester) forms of 2,4-D pose an unacceptable risk to crops and the environment.
To minimise the risks to people and the environment the APVMA proposed cancelling all approvals and registrations relating to the short-chain esters forms (ethyl ester, butyl ester and isobutyl ester) of 2,4-D. Read a full history of the review...
The APVMA will issue a final report once the assessment of all available data is completed.
