Chateau® Herbicide Overview

How Chateau Works

  • Chateau contains flumioxazin, a powerful long-lasting preemergence herbicide.

  • A PPO inhibitor, Chateau’s mode of action is different than many other commonly used herbicides. So it helps fight resistance, while providing long-lasting control of tough weeds.

  • Chateau has some postemergence activity, but its strength is preemergence residual action.

  • Chateau requires at least ¼ inch of rainfall or irrigation to activate preemergence activity.
