AI: 21.4% Bromacil. An effective general herbicide for use on non-cropland areas for control of brush and many annual and perennial weeds. Particularly useful for control of perennial grasses. It is a water soluble liquid to be mixed in water and applied as a spray. May also be applied undiluted for basal (soil) treatment for brush. Effects are slow to appear and may not become apparent until the chemical has been carried into the root zone of the weeds by moisture. The degree of control and duration of effect will vary with the amount of chemical applied, the soil type, rainfall, and other conditions.
