Dimethoate

Dimethoate review

Status: review in progress

Update:

  • 24 September 2013 – suspension of certain dimethoate products continued to 5 October 2014
  • 7 March 2013—the Exposure and Risk Assessment component Exposure and Risk Assessment component (OHS component March 2013) (PDF, 1.7MB) | (DOC, 1.2MB) of the Human Health Risk Assessment of Dimethoate has been completed and published. This assessment, including the occupational health and safety risks associated with the use of dimethoate, has been prepared by the Office of Chemical Safety (OCS).

    This release follows the publication of the Human Health Risk Assessment of Dimethoate—Toxicology component in January 2011 and the Dimethoate Residues and Dietary Risk Assessment Report in August 2011.

    The APVMA plans to publish Preliminary Review Findings for dimethoate and then seek comments and information that may be used to refine the toxicology, OHS and residues assessments prior to finalising the review. This may include any available studies, and descriptions of work practices such as application rates per hectare and hectares treated per day. The APVMA will also consider any proposals to amend label directions to address any identified concerns.
  • 25 September 2012—suspension of most dimethoate products continued to 5 October 2013.

On 6 October 2011 the APVMA suspended all products containing dimethoate and issued new instructions that no longer allow the use of dimethoate on a number of food crops due to potential dietary risks. The suspension and associated permits have been extended to 5 October 2014. The suspension prohibits:

  • use of dimethoate on certain horticultural crops
  • use on all food producing plants in the home garden
  • supply and possession of dimethoate products unless they carry the new instructions for use.

The suspension follows the release of the 2011 Dimethoate Residues and Dietary Risk Assessment Report (August) which found that its use on many crops could exceed the recommended public health standard (the Acute Reference Dose).

Certain dimethoate products have had the suspension of their registrations revoked to allow the approval of new labels that have instructions consistent with the suspension instructions. Previous labels of these products (those approved before 6 October 2011) must still be used only according to the current suspension instructions included in PER13155 or PER13156 or according to any other permits issued by the APVMA.
