Oust® XP Herbicide

Controls Tough Annual and Perennial Grasses and Broadleaf Weeds in Forestry and Non-crop Sites

DuPont™ Oust® XP is a broad-spectrum herbicide that cost-effectively controls tough annual and perennial grasses and broadleaf weeds, including chickweed, fescue, crabgrass, white snakeroot, and yellow nutsedge, in forestry and non-crop sites.

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, Oust® XP controls weeds by both preemergence and postemergence activity; and when applied on dry fertilizer, Oust® XP 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.
