Tough Weeds Meet Strong Herbicides at Brooklyn, WI, Grow More Experience Site
Clean soybean rows at the Brooklyn, WI, Grow More™ Experience site.
When weeds emerge, they compete with crops for resources in a variety of ways. Larger weeds – like giant ragweed – can outgrow soybeans, competitively stealing sunlight, water and nutrients from the crop, while smaller weeds – like waterhemp – are heavy seed producers that can be detrimental to crop growth many seasons into the future. As resistance spreads through a field, protecting your yield from weeds becomes harder and harder.
To protect your soybean crops from resistant weeds, you need to use every tool available, including:
- Applying residual herbicides at full rates.
- Using multiple effective sites of action.
At the Brooklyn, WI, Grow More Experience site, our bare-ground herbicide trials offer a firsthand look at the value of using full rates of products within the Syngenta soybean herbicide that offer long-lasting residual control.

It can be tempting to save money by cutting rates, but in the long run, it’s more cost-effective and efficient to follow the labeled rate. Using the full rate in your herbicide application helps prevent weed escapes and further resistance issues. In our bare-ground trials, we compared different rates of Boundary 6.5 EC herbicide for soybeans, and we’re seeing better, longer-lasting control of a larger spectrum of weeds when we use the full rate.

You can also limit weed escapes and the development of resistance by making sure weeds are managed throughout the season with residual control. To best protect your ROI, we recommend a herbicide program with overlapping residuals and multiple effective sites of action for long-lasting protection.
Prefix herbicide offers a flexible application window and residual control with 2 effective sites of action. Tavium Plus VaporGrip Technology – the first dicamba herbicide premix – also offers 2 effective sites of action to manage key resistant weeds and keep fields clean. Tavium contains contact control to help manage the weeds you see, and residual control to help manage the ones you don’t see yet. As shown above, overlapping residuals with multiple effective sites of action help keep fields cleaner longer than 1 site of action on its own.
Work with your local agronomist or Syngenta sales representative to create a full-season weed management plan to fit your farm’s needs and delivers the best ROI.
