BioBarrier - Model 4407-101 - 24 Inch x 100 Ft Typar Biobarrier Root Fabric - Brochure

BioBarrier® root control system is a Typar® geotextile which incorporates trifluralin nodules that prevent root growth by deflecting the roots away and acts as a barrier. A small amount of the trifluralin herbicide is released and as it biodegrades, it is continually replaced ensuring a long life and effectiveness of the herbicide zone.
