Oust® Extra

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

Oust Extra controls many annual and perennial grasses and broadleaf weeds in conifer plantations and non-crop sites. It also may be used to control certain hardwoods and vines when applied in site preparation treatments. Oust Extra may be used for general weed control on terrestrial non-agricultural sites and for selective weed control in certain types of industrial turfgrasses on these same sites. Oust Extra may be used for the control of certain woody plants, vines and herbaceous weeds in site preparation and release of various conifers.


Oust Extra can be tank mixed with other herbicides registered for use in conifer plantations and non-crop sites; when tank mixing, use the most restrictive limitations from the labeling of both products.

Please see the product label for a full list of weeds controlled. Do not use on crops.

Always read and follow label instructions.
