Westar® Herbicide

Delivers Both Contact and Residual Activity for Season-long Control of Key Broadleaf Weeds

DuPont™ Westar® Herbicide makes conifer site preparation and release easier and faster.

Westar® herbicide delivers both contact and residual activity for season-long control of key broadleaf weeds as well as annual and perennial grasses in conifers grown for forestry and Christmas tree production as well as non-crop sites.

Westar® may be applied prior to planting conifers or over the top of dormant seedlings. One application reliably controls downy brome, fleabane, Italian ryegrass and sedges and other tough species. Excellent product suspendibility aids consistent and uniform spray coverage and re-suspends easily after delays for rain and wind for added convenience.
