Oust EXTRA herbicide provides long-lasting foliar and residual control of a broad spectrum of woody vines, troublesome brush, and broadleaf weeds. When you’re able to keep conifer plantation sites clear of weeds and unwanted brush, the trees can grow bigger and faster and develop deeper and more robust root systems, which leads to more rapid diameter and height growth. Oust EXTRA does the job, delivering both pre- and post-emergent control. It’s the ideal product for your conifer site preparation program.

When applied in site preparation treatments, it may also control certain hardwoods and vines.

Oust EXTRA delivers proven performance on over 100 tough broadleaf weeds and grasses, including ragweed, dandelion, and lambs quarter. It is a dispersible granule herbicide that can be mixed in water and applied as a spray or impregnated on dry, bulk fertilizer. When applied as a spray, it is absorbed by plants’ roots and foliage, rapidly inhibiting the growth of susceptible weeds. When applied to dry fertilizer, it is absorbed primarily by the roots. For best results, apply before or during the early stages of weed growth before weeds develop an established root system. For additional flexibility and control, Oust EXTRA can be tank mixed with other herbicides registered for use in conifer plantations and non-crop sites.
