Barrier Ornamental Landscaping Herbicide

Barrier Ornamental Landscaping Herbicide, manufactured by PBI Gordon, is a professional soil sterilant granule herbicide that delivers season-long weed control with just one application, making it an essential tool for property managers, landscape professionals, and homeowners looking for reliable vegetation management.

It contains dichlobenil, which is a soil-activated herbicide that prevents weed seeds from germinating, offering months of control with a single application. It forms a chemical barrier in the soil, stopping weeds before they start, making it an ideal solution for prevention-focused weed management.

Barrier Ornamental Landscaping Herbicide is an effective non-selective herbicide granule for long-lasting vegetation control in non-crop, ornamental, and industrial areas. Its broad-spectrum weed control, residual activity, and soil-sterilizing properties make it ideal for professionals and property owners looking to maintain clean, weed-free grounds.

Tools Needed

A push or broadcast spreader will be needed. 

How to Use

• Step 1: Determine how much Barrier Ornamental Landscaping Herbicide to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiplying them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). For annual and biennial weeds, apply 2.3 to 3.4 pounds of Barrier Ornamental Landscaping Herbicide per 1,000 sq. ft. For perennial weeds, use 3.4 to 4.6 pounds of product per 1,000 sq. ft. Do not apply more than 150 pounds of product per acre on Azalea, Boxwood, Euonymus, Forsythia, Heather, Holly, Ivy, Lilac, Leucothoe. Refer to the product label for specific application rates and restrictions. 
• Step 2: Adjust the spreader to the proper calibration, and then load the granules. 
• Step 3: Distribute granules uniformly over the soil surface. If treatment is followed by application of 1⁄2 to 1 inch of water by overhead irrigation, the lower rates are recommended. Shallow incorporation immediately after application is recommended in southern states. In other areas, shallow incorporation or sprinkler irrigation is suggested when applications are made during periods of high temperatures.
