Canada Grants Epyrifenacil Herbicide Registrations

Health Canada has granted registrations for S-3100 Technical, S-3100 0.46 EC Herbicide and V-10488 0.94 SE Herbicide, which contain epyrifenacil. Registration Decision RD2026-20, published on 4 November 2026, authorises sale and use under subsection 8(1) of the Pest Control Products Act.

The decision concerns specified applications and approved conditions of use. Health Canada concluded that the products’ health and environmental risks and value were acceptable under those conditions.

Approved Crop And Vegetation Uses

S-3100 0.46 EC Herbicide is registered for pre-plant surface applications to canola, field corn, and spring and winter wheat. For soybean, it covers pre-plant surface and pre-emergence applications.

V-10488 0.94 SE Herbicide covers pre-plant surface applications to spring wheat and pre-emergence applications to soybean. Both products also have uses in fall burndown and fallow-land programmes, maintaining bare ground on non-cropland, and industrial vegetation management.

Consultation And Objections

The final decision follows Proposed Registration Decision PRD2026-13. Its 30-day consultation ended on 20 September 2026. Health Canada says the final decision is consistent with that proposal and records that it received comments on the health, environmental and value assessments.

Notices of objection must be based on scientific grounds and can be filed within 60 days of publication. They must include the required form, scientific explanation and supporting evidence or specific Health Canada documentation.

The regulator categorises epyrifenacil as requiring higher proportional effort on environmental grounds. It also says scientific literature and regulatory information for the active ingredient will be monitored through continuous oversight.
