What is it?

Oxadiazon is a selective pre-emergent herbicide, which means it targets weed seeds before they germinate without affecting the established plants. It is commonly used in turf management, ornamental plantings, and in agricultural settings to control annual grasses and broadleaf weeds. It is available in various formulations, including granules and liquid concentrates.

How does it work?

Oxadiazon works by creating a chemical barrier on the soil surface. When weed seeds begin to germinate and come into contact with the herbicide, the active ingredient inhibits the development of chlorophyll, essential for photosynthesis. As a result, the young weeds are unable to produce the energy needed for growth and ultimately die off before emerging from the soil.

Benefits

• Effective Pre-Emergent Control: Targets weeds before they emerge, preventing competition with desired plants.
• Long-Lasting Residual Action: Provides extended control, reducing the need for frequent reapplication.
• Selective Action: Safe for use around established turf and ornamental plants when used as directed.
