BioBarrier
What is BioBarrier?
BioBarrier is an award winning, state of the art technology using the finest materials. Designed as a long-term solution for vegetative root intrusion and possible structure damage, BioBarrier combines a woven geotextile fabric with the effective pre-emergence herbicide Trifluralin. Trifluralin, the active ingredient in BioBarrier, has been used extensively in commercial applications for more than 35 years and is widely recognised as a leading pre-emergence herbicide.Utilising a patented controlled-release process, BioBarrier delivers only the amount of Trifluralin biologically necessary to inhibit root growth. BioBarriers? innovative technology ensures that precise amounts of herbicide will be dispersed at the correct location for an extended period of time. This provides a distinct advantage over repeated applications of herbicides required by conventional methods.
How does BioBarrier work?
BioBarrier consists of composite nodules injection-moulded through Typar (a spun-bonded polypropylene geotextile fabric) the through injection moulding technique ensures permanent nodule attachment. Impregnated with Trifluralin, the nodules function as a protective reservoir. The nodule composition is designed to slowly release trifluralin vapours which adsorb in the soil.
Outside the nodule, the trifluralin degrades but is continuously replaced by new material, building and maintaining a root inhibition zone. Accurate nodule spacing ensures the individual nodule zones overlap and reinforce each other. At equilibrium, the inhibition zone becomes contiguous, enveloping the BioBarrier fabric.
When roots enter the inhibition zone, root tip cells cannot divide (multiply) preventing growth in that direction (similar to pruning). Trifluralin is not systemic; therefore it is not taken into the plant. As a result, the root system is diverted away from the BioBarrier protected structure without adversely affecting the desirable plants or trees. Root branches outside of the zone are NOT affected.
