• Abstract:
  Straw mulch proved more effective in erosion control than re-claimed paper mulch in East Texas. Straw mulch anchored by asphalt or latex was significantly superior to a resin anchored straw mulch. There was no significant difference of Bermuda grass seedlings per square foot with latex or asphalt anchors. Bermuda grass and weeping lovegrass were the most effective species tested for revegetating acid slopes. Addition of phosphate at the rates tested provided no advantage in seedling emergence. Water-degradable polymer additive to trichloroacetic acid (TCA) at 18 lbs. TCA/ft mile was significantly superior to TCA at 24 lb./ft mile rate 60 days following treatment. African rue can be herbicidally controlled with glyphosate (3 lb./A) with a fall application or with tebuthiuron (4 lb./A) or Vel-5026 (4 lb./A) with a spring or fall application. Velpar proved to be an effective herbicide for the general control of unwanted vegetation along roadways. Johnsongrass and alfalfa are resistant to this herbicide. Avoidance of desirable species must be practiced. Rates to 16 lbs./A or 2 lbs./ft mile did not significantly move from the target area when applied to soil. Velpar was over applied on asphaltic medians and movement did occur. If applied to large asphaltic areas care must be taken to prevent excessive applications.
