How Barrier Herbicide Works

This fast-acting herbicide contains imazapyr and glyphosate, two isopropylamine salts that not only kill weeds but also prevent them from growing for up to 12 months. With one application, Barrier Herbicide seeps into a weed's root system and stops its growth. It goes to work within days and provides residual control without the need to reapply the product on the same area. It also creates a vapor barrier in the uppermost layer of the soil, helping to stop regrowth long after an application.


Where to Use Barrier Herbicide

Barrier herbicide works to kill weeds on most noncrop sites, such as home lawns and business landscapes. It has a quick mode of action and begins to stop weed growth on established landscapes at hospitals, sports complexes and parks. It's activated with both irrigation and rainfall.
