2025 Pre-Seed Herbicide Selector

The foundation to effective weed control, including herbicide resistant weeds, is to start with a weed-free field.
This means controlling existing weeds with a pre-seed/pre-emergent herbicide treatment.
Current research indicates that a pre-seed/pre-emergent treatment of glyphosate should include multiple tank mix partners using different chemical groups (sites of action) to delay and manage the start of new herbicide resistant biotypes.
The chart below presents various tank-mix burnoff options for combining with glyphosate to effectively control a wide range of weeds as a pre-seed application. This chart is based on a comprehensive database of over 30 herbicides that can be mixed with glyphosate to target more than 60 different weed species.

Apply Pre-seed to these crops | Target Weeds |
# For pre-seed applications in the spring, injury to pulse crops may occur on coarse-textured soils, low in organic matter (less than 3%), or in fields with variable soils, gravelly areas, sandy areas or eroded knolls. Avoid planting pulse crops in soils containing more than 50% sand.
* All Kochia across Western Canada is considered Group 2 resistant. There are also populations of Gp2+ Gp4, Gp2+Gp9, and Gp2+Gp4+Gp9 resistant kochia. For Kochia control, glyphosate should be tank-mixed with other modes of action/groups labelled to control kochia. Seed from breakthrough kochia should be tested for resistance.
