Barrier Ornamental Landscaping Herbicide, Ideal for Application Under Mulch


Barrier Ornamental Landscaping Herbicide
delivers dependable non-selective control of annual and perennial weeds, including dandelion, crabgrass, bluegrass, ragweed, lambsquarters, and more as listed. Designed for use in established landscape and non-crop settings. Barrier is ideal for institutional sites such as hospitals, sport facilities, cemeteries, and apartment complexes.


Barrier Herbicide is activated with rainfall or irrigation at temperatures above 60°F. When the active ingredient is washed off the granule, Barrier attaches to soil organic matter and the granules release the active ingredient, creating a "vapor barrier" in the upper two inches of the soil that slowly kills existing shallow-rooted weeds and grasses.
