Health Canada's Pest Management Regulatory Agency (PMRA), pursuant to subsection 8(1) of the Pest Control Products Act, is granting registration for the sale and use of Luna Privilege Greenhouse Fungicide containing the technical grade active ingredient fluopyram, to control powdery mildew (Erysiphe spp. and Podosphaera spp.) and botrytis blight (Botrytis spp.) on greenhouse grown ornamentals and outdoor ornamentals.

Fluopyram is a member of the succinate-dehydrogenase inhibitors (SDHI) fungicides and is the active ingredient in Luna Privilege Greenhouse Fungicide. Luna Privilege Greenhouse Fungicide is applied via foliar, drip or drench applications for the management of various fungal diseases on various crops.

Botrytis blight and powdery mildew are major concerns for producers of ornamental plants under either field or greenhouse conditions as any signs of infection may render their product unmarketable. Luna Privilege Greenhouse Fungicide, applied to foliage according to label directions is expected to provide effective disease management against botrytis blight and powdery mildew on ornamentals and, specifically, powdery mildew on roses. The registration of Luna Privilege Greenhouse Fungicide for these uses will provide producers of ornamental plants, including roses, with an additional product option to manage major diseases in crops that have characteristically low economic tolerance for any signs of fungal infection.

The Proposed Registration Decision PRD2024-10, Fluopyram, Luna Privilege Greenhouse Fungicide, containing the detailed evaluation of the information submitted in support of this registration, underwent a 45-day consultation period ending on 4 February 2025. The evaluation found that, under the approved conditions of use, the health and environmental risks and the value of the pest control product are acceptable. Health Canada received comments relating to the health assessment during the public consultation period conducted in accordance with section 28 of the Pest Control Products Act.
