Farmers don’t’ like to choose between flexibility and efficacy when it comes to weed control and with CONQUER® II they don’t have to. CONQUER II has become a preferred pre-seed burndown option for many Western Canadian farmers ahead of canola, offering outstanding control of tough weeds while maintaining flexibility when last minute change is required.
While CONQUER’s primary use is ahead of canola, one of the herbicides greatest advantages is its safety ahead of multiple crops ensuring farmers have the freedom to adjust their plans, if necessary. Additionally, CONQUER II has no residual activity in the soil,
Powerful Pre-Seed Weed Control
Effective early weed control is critical for maximizing yield potential. Weeds compete aggressively with emerging seedlings for moisture, nutrients and sunlight, which can significantly impact stand establishment. CONQUER II uses two modes of action, Group 6 and 14, to deliver powerful control of broadleaf weeds like kochia, cleavers, narrow-leaved hawk’s-beard, and many more, ensuring that crops can establish themselves in a clean, competition-free environment.
Flexibility in Crop Rotation and Application Timing
One of the standout features of CONQUER II is its versatility in cropping systems. While it is primarily used ahead of canola, it is also safe to apply before a range of other crops, giving farmers much-needed flexibility should their seeding plans change. This adaptability is particularly valuable in Western Canada, where weather and market conditions can sometimes force last-minute cropping decisions.
Since CONQUER II does not have residual activity, it minimizes concerns about carryover effects on future crops. Farmers can confidently use it in their pre-seed burndown programs without worrying about unintended impacts on labelled crops.
Fast and Effective Burndown for Canola and Beyond
Farmers growing canola understand the importance of early weed removal. Since canola is a relatively non-competitive crop in its early stages, eliminating weeds before seeding is crucial to ensuring strong emergence and uniform stand establishment. CONQUER II fits perfectly in this approach, offering fast-acting weed control that helps maximize canola yields. Once canola becomes established it is better able to compete with weeds.
Beyond canola, CONQUER II also provides exceptional performance in pre-seed burndown applications for cereals.
Tank-Mixing for Enhanced Weed Control
Many growers tank-mix CONQUER II with glyphosate to achieve a broader spectrum of control of both grass and broadleaf weeds with a single pass.
An Effective Tool for Resistance Management
Herbicide resistance is a growing concern in Western Canada. Many farmers have seen a rise in resistant broadleaf weeds. Herbicide tolerant crop genetics have allowed farmers to become more efficient, however, it’s important that farmers maintain best practices to extend the benefits of traited crops well into the future. One of the ways this can be done is to preserve the effectiveness of herbicides.
Using CONQUER II along with glyphosate ahead of canola helps ensure a better pre-seed burndown to reduced weed competition. This not only helps promote a healthier crop but also means there are fewer, smaller weeds at in-crop timing. These smaller, more susceptible, weeds at in-crop timing means fewer survivors to re-populate and wreak havoc in the future. Better weed control at every application timing helps elongate the efficacy of today’s herbicide options.
Using CONQUER II in rotation with other canola herbicides ensures that different, effective weed control products are employed throughout the season, slowing down the development of resistance and maintaining herbicide effectiveness for future growing seasons.
Maximizing Performance with Best Practices
To get the most out of CONQUER II, farmers should follow key best practices when incorporating it into their weed management programs:
- Apply in Early Spring – Timing is critical for effective weed control. Applying CONQUER II before weeds reach advanced growth stages ensures maximum efficacy and prevents weeds from competing with newly emerging crops.
- Use the Right Water Volume – Carrier volume impacts herbicide performance. Using adequate water ensures proper spray coverage, leading to better weed control.
- Tank-Mix for Broader Control – Consider mixing CONQUER II with glyphosate to control both grass and broadleaf weeds effectively.
- Spray Under Optimal Conditions – Avoid spraying during temperature inversions or when wind speeds are too high, as this can reduce herbicide contact and increase the risk of drift. Apply when weeds are actively growing.
- Monitor Fields for Weed Pressure – Even after application, scouting fields regularly helps assess whether additional weed control measures are needed.
A Reliable Choice for Canadian Farmers
With its proven performance, flexibility in crop rotations, and ability to deliver rapid weed control, CONQUER II is a trusted tool in Canadian agriculture. Whether used ahead of canola or cereals it provides the clean start crops need while giving farmers peace of mind in their weed management strategy.
By integrating CONQUER II into a well-planned pre-seed burndown program, farmers can maximize their crop yields, protect against herbicide resistance, and maintain long-term field health. The compatibility with glyphosate, and benefit of no-residual activity make it an excellent option for those looking for effective and flexible weed control in Western Canada.
