Kixor® Active Herbicide: The New Standard in Broadleaf Weed Control

Kixor active herbicide is the new standard in broadleaf weed control. A highly effective selective herbicide, Kixor was the first in a new chemistry class of pyrimidinedione for use in a wide range of crops. When applied prior to crop emergence, this protoporphyrinogen IX oxidase (PPO) inhibitor active ingredient, saflufenacil, acts as a potent chlorophyll biosynthesis inhibitor. It provides burndown of emerged broadleaf weeds and offers season-long residual broadleaf control when used at higher rates in corn and sorghum. Kixor can be used in a variety of crops from cereals to citrus and controls more than 70 broadleaf weeds making it the new standard for control. Kixor is sold as Sharpen® herbicide and Heat® herbicide.

Key Features and Benefits of Kixor®


  • A new class of chemistry
  • Broad-spectrum control of weeds without the need for atrazine
  • Rapid foliar burndown and residual soil activity
  • Compatible with other herbicides used in farming to provide broad-spectrum weed control and crop protection


  • Excellent control of all major broadleaf weeds, including glyphosate-, ALS- and atrazine-resistant biotypes
  • Safe for use in multiple crops and rotational systems
  • Favorable environmental, toxicological and ecotoxicological profile

Mode of Action

Kixor herbicide is the first in the class known as pyrimidinedione in North America. It is quickly absorbed by the weed’s roots, shoots and leaves. Once absorbed, it moves throughout the weed. Kixor works by inhibiting a key step in chlorophyll biosynthesis. This results in rapid loss of cell membrane integrity leading to cellular leakage, tissue necrosis and, ultimately, death of the broadleaf weeds.
