Consultation on Straight Chain Lepidopteran Pheromones and their Associated End-use Products, Proposed Re-evaluation Decision PRVD2021-07

Notice to the reader:

The online consultation is now closed.

Health Canada is consulting Canadians on the proposal to continue registration of Straight Chain Lepidopteran Pheromones (SCLPs) and associated end-use products registered for sale and use in Canada.

SCLPs are naturally occurring semiochemicals produced by moths and butterflies, and when used in pest control products, SCLPs are synthetic versions of these naturally occurring compounds. The SCLPs are registered to control several different moth populations in pome and stone fruit trees, tree nuts, grapes, outdoor woody ornamental trees (ties and canisters), and in forests and woodlands (pellets and microcapsules via aerial application).

The Proposed Re-evaluation Decision (PRVD2021-07) presents the re-evaluation of a number of SCLPs, which Health Canada's Pest Management Regulatory Agency has grouped on the basis of use pattern as well as their structural and toxicological similarity.

The SCLP products listed in Appendix I of the PRVD are proposed for continued registration in Canada. When the current label directions are followed, potential risks to human health and the environment are considered to be acceptable. As a result of the re-evaluation of the SCLPs, no further risk mitigation measures for product labels are proposed. To meet current standards, label updates for specific products are proposed in the PRVD.

For more information on the proposed decision open the “Proposed Re-evaluation Decision”.
