Consultation on (S)-Kinoprene and its Associated End-Use Products, Proposed Re‑evaluation Decision PRVD2020-11

Health Canada is consulting Canadians on the proposal to cancel the registration of (S)-kinoprene and all associated end-use products for sale and use in Canada.

(S)-Kinoprene is an insect juvenile hormone analogue applied by foliar spray that inhibits insect growth during the moulting process. The pesticide is valued in controlling aphids and whiteflies, and suppress mealybugs on greenhouse ornamental plants. However, risks were identified for occupational workers that were not shown to be acceptable when the pesticide is used according to label directions or additional mitigation measures considered. (S)-Kinoprene was also found to present potential risks to certain terrestrial and aquatic organisms.

(S)-Kinoprene is the active ingredient in the currently registered commercial product Enstar®EW Insect Growth Regulator; more information is available in the Pesticide Label Search database.

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