Health Canada’s Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is proposing registration for the sale and use of Rinskor Active, Milestone NXT Herbicide, Restore NXT Herbicide, GF-3206 Herbicide, GF-3301 Aquatic Herbicide and ProcellaCOR FX Herbicide, containing the technical grade active ingredient florpyrauxifen-benzyl, for weed management in hazelnut and non-agricultural/industrial vegetation management including many invasive species, as well as for aquatic vegetation management to control invasive plants both in and around water.

Florpyrauxifen-benzyl is a new selective herbicide belonging to the arylpicolinate class of herbicides. It acts as a synthetic plant hormone by mimicking the natural plant hormone auxin and disrupting growth processes in susceptible plants. Excessive auxin causes alterations in cell wall elasticity resulting in leaf curling and interference with nutrient transport.

The proposed end-use products Milestone NXT Herbicide and Restore NXT Herbicide are coformulations of florpyrauxifen-benzyl and aminopyralid present as potassium salt. Aminopyralid is a registered herbicide active ingredient (REG2007-01 Aminopyralid). The potassium salt represents a new salt form of aminopyralid. The proposed registrations do not represent expansions of use from currently registered uses of aminopyralid.

An evaluation of available scientific information found that, under the approved conditions of use, the health and environmental risks and the value of the pest control products are acceptable.

This summary describes the key points of the evaluation, while the Science evaluation of Proposed Registration Decision PRD2022-17, Florpyrauxifen-benzyl, Milestone NXT Herbicide, Restore NXT Herbicide, GF‑3206 Herbicide, GF-3301 Aquatic Herbicide, and ProcellaCOR FX Herbicide provides detailed technical information on the human health, environmental and value assessments of florpyrauxifen-benzyl and Milestone NXT Herbicide, Restore NXT Herbicide, GF-3206 Herbicide, GF-3301 Aquatic Herbicide and ProcellaCOR FX Herbicide.
