Final Component of Chlorpyrifos Review Released

3 September 2009

The Australian Pesticides and Veterinary Medicines Authority has released the final component of its review of the insecticide chlorpyrifos.

The new report released - Reconsideration of Registrations and Approvals associated with chlorpyrifos - Preliminary Review Findings Report (2009) (PDF, 910kb) - contains an assessment of new residue data the APVMA required from product registrants in 2000.

Having now assessed that data, the APVMA is proposing to:

  • amend maximum residue limits  for various commodities;
  • further restrict or remove its use from some crops:
  • amend label instructions, including withholding periods; and
  • amend associated export intervals on commodities to protect our trade with major trading partners.

The APVMA invited public comment on the new report until Friday 30 October.

Chlorpyrifos is a broad spectrum, non-systemic oganophosphorus chemical first introduced into Australia in the mid 1960s.

In Australian agriculture it is registered to control a broad range of insect pests in many crops. Around the home, it is also permitted as an insecticide and termiticide.

The APVMA’s review of chlorpyrifos was substantially completed in 2000.  A range of regulatory measures was introduced to limit home and garden uses.  Label restrictions on other chlorpyrifos products were also introduced to protect human health, birds and fish.
