Brush Control

Mesquite

• Ideal Spray Conditions
  • Optimum soil temperature: 78-83 degrees
  • Avoid spraying when plants are in a drought situation and immediately after a large rain (more than three inches) because of poor translocation.
  • Spraying season: 42-63 or 72-84 days after bud-break
  • Workable wind speeds: 2-10 mph
  • Avoid spraying when relative humidity is low (less than 50 percent).
  • Avoid spraying when temperature is extremely high (over 95 degrees).
• Aerial-Spraying Mesquite
  • Mixture
    • 1/4 lb/acre of Remedy, 1/4 lb/acre of Reclaim.
    • 2-4 gallons oil-in-water emulsion (1 pt. to 1 g. diesel fuel oil and water to make ratio is considered optimum)
    • Hand-Spraying Mesquite
      • Stem-Spray
      • • 15 percent Remedy, 85 percent diesel
        • Wet all stems emerging from the ground to 12 inches up each stem.
        • Works well on smooth bark mesquite trees that are less than eight feet tall.
      • Leaf-Spray
        • 0.5 percent Reclaim, 0.5 percent Remedy, 0.25 percent surfactant
        • Mix with water.
        • Spray must contact all leaves.
        • Follow same guidelines for aerial-spraying mesquite.
        • Works well for trees less than eight feet tall.

      Prickly Pear

      • Hand-Spraying
        • Wet both sides of all pads of a plant for an effective mortality rate.
        • Hand-spray any time during the year when some soil moisture is present.
        • Avoid spraying when drift potential is high.
        • Mixture: 1 percent Tordon 22K mixed with water and a surfactant.
      • Aerial-Spraying
        • Prescribed burning before spraying can damage prickly pear pads and allow a lower rate of herbicide for an effective kill rate (1/8 to 1/4 lb/acre of Tordon 22K).
        • Tordon 22K is a restricted-use herbicide.
        • Mixture: 1/4 to 1/2 lb/acre of Tordon 22K. Two to four gallons oil-in-water emulsion (1 pt. to 1 g. diesel fuel oil and water to make ratio optimum).
