Mirex, a so-called organochlorine (PDF, 61kb) available as the product Mirant, was a termiticide used to control the giant termite Mastotermes darwiniensis in horticultural crops and amenity trees in northern Australia.

There are no products containing mirex currently registered for use in Australia.

Mirex is listed as one of the twelve persistent organic pollutants (POPs) under the United Nations Environment Program’s Stockholm Convention on Persistent Organic Pollutants (May 2001). Persistent Organic Pollutants (POPs) are chemical substances that persist in the environment, bioaccumulate through the food web, and pose a risk of causing adverse effects to human health and the environment. For more information on POPs, see the website http://www.chem.unep.ch/

For a few years before 2007, Mirant was the only registered product containing mirex in Australia. The product was registered for use only in the Northern Territory. It is no longer required for the control of the giant termite as there are now effective alternatives.

Mirex Review

Status: Review Completed

No formal review of mirex was conducted as there was only one registered product available and because it was destined for eventual phase-out because of Australia’s obligations under the Stockholm Convention. Furthermore, the Northern Territory Department of Primary Industries developed alternative methods to control the giant termite without using mirex. The registration of the product Mirant ceased after 30 June 2006. The APVMA reduced the typical two-year phase out period normally applicable to chemicals when their registration expires, to seven months. Thus the use of the last mirex product on the Australian market finished on 31 January 2007.
