Optill PRO Herbicide

Optill® PRO herbicide delivers three overlapping sites of action, giving soybean growers preplant and preemergence management of tough-to-control weeds. Powered by Kixor® herbicide technology, it provides fast, broad-spectrum burndown and enhanced residual control.

How It Works

Optill® PRO (Premium Residual Option) herbicide combines Optill® herbicide, powered by Kixor® herbicide technology, with the same active ingredient as in Outlook® herbicide. This powerful combination provides a more complete foundation for soybean growers, helping them to manage resistant weeds more effectively and maximize yield potential. Three overlapping sites of action deliver rapid burndown and enhanced residual control of tough broadleaf weeds and grasses, such as glyphosate-resistant waterhemp and Palmer pigweed.

Key Features and Benefits

  • Preplant and preemergence application flexibility
  • Delivers three overlapping sites of action for resistance management
  • Fast, broad-spectrum burndown and enhanced residual control

Always read and follow label directions.

Problems Controlled

Kixor® herbicide technology has proven powerfully effective on a large array of broadleaf weeds across a wide variety of environments and crops. With its unique foliar and soil activity, Kixor has also proven effective against a new generation of tough-to-control as well as resistant weeds.

In fact, every year, across the country, growers see evidence that an increasing number of different weeds are developing glyphosate resistance. You can find out more about the spread of glyphosate-resistant weeds in your area at www.glyphosateweedscrops.org.
