In addition, Oxadiazon has also shown to be effective on sod farms, ornamentals, vines and trees.

Oxadiazon controls weeds by inhibiting an essential plant growth enzyme known as protoporphyrinogen oxidase or "protox" for short. This inhibition hinders the usual developmental functions of the plant and breaks down tissues.

Applications of Oxadiazon will not hinder turf root growth or recovery, which makes it ideal for application in the spring. Your ornamentals will not be damaged by its application.

Is Oxadiazon Safe?

What To Expect

It is important to apply Oxadiazon at the right time prior to target weed seed germination. Make sure to water the area immediately after application or apply before rainfall. It is also best to eliminate existing weed growth before application to ensure the spray reaches the soil surface.
