Extract

Blue oak (Quercus douglasii) is a common tree on several million acres of grazing land in California. It may occur as pure stands, but other species of woody plants, especially poison oak (Rhus diversiloba), are commonly associated with it. Leonard and Harvey, et al. reported the effectiveness of the cut-surface method using 2,4–D amine for killing blue oak. Unfortunately, killing of the blue oak results in a “release” of some of the under-story shrubs, which may become a problem later. A broadcast spray that will control all the woody plants is needed.
