In September 2000, the APVMA released the chlorpyrifos interim review report. In the report, the APVMA proposed restricting home and garden products to concentrations of not greater than 50 grams per litre. The APVMA also found that there were inadequate residues data for the use of chlorpyrifos in some commodities. The APVMA proposed varying product labels to strengthen environmental protection warnings, safety directions and re-entry period statements. These regulatory actions were implemented in 2001–02.
In September 2009, the Preliminary review findings report, which considered supplementary residues data and provided a summary update on the toxicity of chlorpyrifos, was released for public comment.
Stage one of the chlorpyrifos Proposed Regulatory Decision (PRD) in relation to domestic, home garden and certain public space situations was published on 24 June 2019 for a three month consultation period.
After consideration of all data and assessments, the APVMA has concluded that the use of chlorpyrifos according to its current instructions for use in domestic, home garden, and certain public spaces does not meet the safety criteria listed in sections 5A of the Agvet Code for continued registration and approval.
A proposed regulatory decision on the cancellation of home garden and domestic products under s 34AB was made; notices were given to holders and nominated agents, and published in the Special Gazette of 24 June 2019.
