Barrier® Ornamental Landscaping Herbicide delivers dependable
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 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.
