Biobarrier® Root Control

Biobarrier Root Control System is a unique method of root and weed control that was originally created in response to the U.S. Department of Energy’s need for a product that could be used in the closure cap of hazardous waste sites to prevent root intrusion and any possible chance that hazardous waste could get into the food chain. The BIOBARRIER System manages roots through the slow, controlled release of triflura­lin which diffuses from the protective nodules in vapor form, creating a root inhibition zine in the soil.

The BIOBARRIER System simply diverts the roots and causes the plant to concentrate growth in branch roots away from the trifluralin zone. Because it is a geotextile, the BIOBARRIER System is water permeable, does not disturb soil hydrology and is flexible enough to be contoured to various installation geom­etries.
