    Description

    Fourth-year field evaluations of four trench insert materials, including water-permeable Typar® polypropylene spunbonded fabric, Biobarrier® or Typar® with trifluralin-impregnated nodules, and water-impermeable polyethylene Geomembrane liners of two thicknesses (20 and 30 mil), were conducted to further test the effectiveness of these physical and/or chemical barriers to root transmission for long-term control of oak wilt. Research plots were selected in a mature natural stand of live oaks growing within a residential development site on a predominantly rocky, sandy clay-loam soil type near Austin, Texas.
