Re-evaluation Decision

Under the authority of the Pest Control Products Act, all registered pesticides must be regularly re-evaluated by Health Canada’s Pest Management Regulatory Agency (PMRA) to ensure that they continue to meet current health and environmental safety standards and continue to have value. The re-evaluation considers data and information from pesticide manufacturers, published scientific reports and other regulatory agencies. Health Canada applies internationally accepted risk assessment methods as well as current risk management approaches and policies.

(Z,Z)-3,13-octadecadien-1-yl acetate is registered for use in various trees and bushes to reduce the damage caused by several different moth species. It is a naturally occurring straight-chain lepidopteran pheromone (SCLP), and it is effective in disrupting mating in the peach tree borer moth, the lesser peach tree borer moth, the dogwood borer moth, and the apple clearwing moth. Currently registered products containing (Z,Z)-3,13-octadecadien-1-yl acetate are listed in Appendix I.

This document presents the final regulatory decisionFootnote 1 for the re-evaluation of (Z,Z)-3,13-octadecadien-1-yl acetate. All pest control products containing (Z,Z)-3,13-octadecadien-1-yl acetate that are registered in Canada are subject to this re-evaluation decision.

This re-evaluation decision has gone through a 90-day consultation period as Proposed Re-evaluation Decision PRVD2018-07, (Z,Z)-3,13-octadecadien-1-yl acetate.Footnote 2

No comments were received during the consultation process. Therefore, this decision is consistent with the proposed re-evaluation decision stated in PRVD2018-07.

A reference list of all data used as the basis for the re-evaluation decision is included in PRVD2018-07.
