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.
