In Western Canada, cereal growers know early weed pressure can make or break a season. Kochia, wild buckwheat, cleavers, and volunteer canola don’t wait—and once they’re up and competing, yield potential can start slipping away fast.
That’s why herbicide layering has become a go-to strategy. Instead of relying on a single product or timing, layering spreads weed control across multiple passes and modes of action. The goal is simple: remove weeds early, protect yield potential, and reduce pressure on in-crop options later.
This is where Avireo™ herbicide fits.
Avireo™ herbicide brings together Group 27 and Group 14 modes of action at the pre-seed timing—a combination that is new for Western Canadian cereal growers. Traditionally, Group 27 chemistry has been used in-crop. Moving it earlier, ahead of cereals, improves performance on small, actively growing weeds and delivers fast, reliable burnoff when it matters most.
Applied pre-seed or shortly after seeding, Avireo™ herbicide helps ensure fields start clean before the crop gets established. Removing early competition allows cereals uninterrupted access to moisture, nutrients, and sunlight during the critical establishment window. Equally important, starting clean puts the rest of the weed control program in a stronger position.
Herbicide layering is also a key part of resistance management. Using Groups 27 and 14 at burnoff helps reduce early selection pressure and keeps Groups 2, 4, and 9 available for in-crop use on the same weed spectrum. That flexibility matters as resistant weed populations continue to expand across Western Canada.
Avireo™ herbicide fits naturally alongside other pre-seed and soil-applied options within a layered program. Authority® brand herbicides and Focus® brand herbicides can be used to build additional layers of control, while products like Barricade® III herbicide and Travallas® Complete herbicide provide further in-crop options when needed.
Herbicide layering doesn’t have to be complicated. It’s about making smart decisions at the right time. By using Avireo™ herbicide as the burnoff layer, cereal growers can start clean, keep in-crop options open, and build a weed management program that’s better equipped to handle resistance and real-world field conditions.
