Spike 20P Specialty Herbicide


Spike 20P herbicide provides premium, long-term control of the toughest brush species. Most brush herbicides are applied to foliage and work into the brush from the leaves down. Spike 20P works differently than other methods because it is applied to the soil surface and works through the root system to achieve brush control. With the active ingredient tebuthiuron, Spike 20P is formulated as heavy, high-density clay pellets that stay stable on the soil surface and resist breakdown. This formulation makes Spike 20P a smart choice when drift is a concern.
