Consultation on Cyclaniliprole 50SL Insecticide containing cyclaniliprole, Proposed Registration Decision PRD2023-11

Current status: Open

Opened on 13 December 2023 and will close for consultation on 27 January 2024.

Health Canada is consulting the public and seeking your feedback on the proposed registration decision to add new uses to the label of the pesticide product Cyclaniliprole 50SL Insecticide. These proposed new uses include outdoor and greenhouse ornamentals, greenhouse pepper, and greenhouse tomato.

What is cyclaniliprole

Cyclaniliprole is an insecticide currently used to suppress or control various insect pests (such as certain thrips, moths, beetles, and flies) on:

The pesticide product Cyclaniliprole 50SL Insecticide contains the active ingredient cyclaniliprole.

Why the new uses are needed

Growers in Canada identified the need for a new pesticide product to manage pests on outdoor and greenhouse ornamentals, greenhouse peppers, and greenhouse tomatoes. The insect pests targeted for control on greenhouse ornamentals are known for developing resistance to conventional insecticides. Having more than one active ingredient available is important for resistance management. Cyclaniliprole provides a new alternative active ingredient for this use. In addition, approving the use of Cyclaniliprole 50SL Insecticide on outdoor ornamentals and greenhouse vegetables provides growers in Canada with more options for effective crop protection that were not available previously. The new uses for Cyclaniliprole 50SL Insecticide were reviewed under the User Requested Minor Use Label Expansion program (URMULE).

What is the proposed registration decision

Health Canada proposes to approve the use of the pesticide product Cyclaniliprole 50SL Insecticide on:

This decision is proposed provided that new key risk-reduction measures are followed, such as modified precautions and application directions that help minimize exposure of cyclaniliprole to bees, other beneficial insects, and aquatic habitats.

To reach its decision, Health Canada conducted scientific evaluations to determine the potential impact of the new Cyclaniliprole 50SL Insecticide uses in Canada. This included reviewing any new and applicable information related to directions for use, toxicology, occupational and residential exposure, dietary exposure, value, and impact on the environment for cyclaniliprole. Results from these evaluations show that the new Cyclaniliprole 50SL Insecticide uses are effective and needed in Canada and would continue to meet Health Canada's requirements for the protection of human health and the environment. For this reason, Health Canada is proposing to approve these new uses.
