Bio barrier is a multi-year root control system consisting of time-release nodules impregnated with a herbicide. The nodules are attached permanently to a flexiable and permeable geotextile fabric which can be contour applied to a wide variety of applications and which will inhibit plant root encroachment in the applications set forth below. Biobarrier controls roots by establishing an in-soil barrier plant of Trifluralin, which prevents root tip cell division. Roots are either stopped or redirected away from structures. Trifluralin is not systemic but can limit root mass. The multi-year feature of Biobarrier is provided by the time release mechanism which continues to meter out the Trifluralin into the soil as the exposed trifluralin biologically and chemically degrades. Structure protection is provided by placing the Biobarrier fabric between the root source and the structure. Since the fabric is flexible and permeable installation may be custom contoured to obtain the most desirable root system redirection for the application and/or to accommadate obstacles.
