Win the Battle Against Resistant Weeds

Take steps to manage herbicide resistance in your area.

Are you keeping your herbicide program effective for your farm’s future? Choose a herbicide program that will last for the next generation.

When it comes to the future of your operation, actions speak louder than words. For decades, Syngenta has been collaborating with university experts and conducting research to solve problems associated with resistant weeds. And when you look at your current toolbox for managing resistance, many of the herbicides currently available contain active ingredients originally developed in our labs.

With our Resistance Fighter® program, you can depend on localized solutions crafted by our agronomy experts who live and work in your area. You will also gain access to the most diverse, effective herbicide portfolio available to successfully manage resistant weeds in your area.

Why has our Resistance Fighter program always had your back? Because we’ve always thought that the only legacy worth having is one built upon preserving yours.

Tips for Good Stewardship:

  • Start clean, utilizing tillage or an effective burndown plus a pre-emergence residual herbicide application
  • Always use a two-pass, pre- and post-emergence system with herbicides at full labeled rates
  • Use multiple effective sites of action with overlapping residuals
  • Use diversified management programs such as cover crops, mechanical weed control and crop rotation
  • Do not allow weeds to go to seed and add to the seed bank
  • Utilize good agronomic practices – narrow rows, increased plant populations and other practices that promote crop growth and competitive ability

“Competitor programs might start clean, but they get dirty, and then you have to spray the post-emergent application to clean it up again. The nice thing with a Syngenta program is you stay clean and you can target those small, less than 4-inch-tall weeds.”

“Half rates haven’t been able to do the job that you’re looking for. Running full herbicide rates gives you as much active ingredient as possible to help try to manage these harder-to-control weeds."

“We’ve been dealing with resistant weeds for a good five years, and it’s become noticeably tougher in the last five years. It creates new challenges. Timely applications and using different sites of action are key when managing resistant weeds.”
