Health Canada’s Pest Management Regulatory Agency (PMRA) has approved Tridem, Avenza, and Rezuvant herbicides for use in Canada. The three cross-spectrum solutions part of Corteva Agriscience’s cereal herbicide portfolio will be available in Western Canada for spring 2019.

Tridem and Avenza are engineered for the brown soil zones. Each contain a new broadleaf weed control solution providing control of kochia (Group 2 and Group 9 resistant), narrow-leaved hawks beard, wild buckwheat, and perennial weeds such as Canada thistle. For grass weed control, Tridem contains a Group 2 mode-of-action solution for wheat, and Avenza contains a group Group 1 solution for barley.

Rezuvant is for barley and is built for black soil zone regions, complementing Rexade for wheat, another cross-spectrum solution Corteva released in 2018. Rezuvant combines an Group 4 annual broadleaf weed control solution with a Group 1 grass herbicide. Rezuvant contains Arylex active, allowing for application and staging flexibility.

“Wheat and barley are important crops to farmers across Western Canada. Getting powerful control of annual and perennial weeds, with rotational freedom to common regional crops, is critical,” explains Mark Alberts, cereal herbicides product manager with Corteva Agriscience.
