Product Literature


Oust XP is a broad-spectrum herbicide that cost-effectively controls tough annual and perennial grasses and broadleaf weeds. It’s ideal for use in rights-of-way, industrial areas, forestry and non-crop sites. This selective herbicide has set the standard for long-lasting, broad-spectrum control. It’s an ideal foundation for residual control and bareground treatments on non-crop sites.

Unlike many competitive products that require pounds of gallons per acre, only a few ounces of Oust XP per acre are used to manage weed problems. Initial symptoms can be seen within 2-3 weeks.

Oust XP herbicide is a dispersible granule that is mixed in water and applied as a spray or impregnated on dry, bulk fertilizer.

When applied as spray, it controls weeds by both preemergence and postemergence activity. When applied on dry fertilizer, it controls weeds by preemergence activity. The best results are obtained when the application is made before or during the early stages of weed growth before weeds develop an established root system. In addition to forestry sites, it can be used at varying rates for bareground treatments, selective weeding on roadsides and in other industrial turf applications. It can be tank mixed with other suitably registered herbicides for additional control and flexibility.
