Low-volume foliar

High-volume foliar:


  • Treats the target brush with total spray solution volumes between 100 and 400 gallons per acre. See the product labels for specific rates.
  • Densities higher than 1,500 stems per acre.
  • Heights greater than 6 to 8 feet.
  • For reclamation efforts in large areas.

Low-volume foliar:

  • Treats the target brush with total spray solution volumes between 5 and 30 gallons per acre. See the product labels for specific rates.
  • Used to keep shrubs and saplings from repopulating an area after an initial reclamation or to enhance a well-maintained site that contains low stem densities and low average stem heights.
  • Densities less than 500 stems per acre.
  • Heights less than 6 to 8 feet.
  • This close-range treatment helps minimize drift.
  • Coverage is quick and easy.
  • Requires minimal equipment, herbicide and personnel.
  • Low-profile.

Application Basics:
High-volume foliar:

  • Always read and follow the product label for specifics.
  • Thoroughly spray all leaves, stems and root collars until wet.
  • Use a nozzle that sprays coarse droplets to get the needed coverage.
  • Spray pressure should never exceed 40 psi at the tip.
  • Add a drift control agent and leave an appropriate buffer zone when applying next to sensitive crops.
  • Thoroughly wet leaves and stems when using bark-penetrating products like Garlon®, Tordon® or DMA® 4 IVM herbicides.
  • Thoroughly wet leaves only when using products like Accord® or Rodeo® herbicides, which are absorbed only through the leaves.
  • Treat root collars when applying products like Garlon, Tordon or DMA 4 IVM herbicides to prevent resprouts from dormant buds in this region.

Low-volume foliar:

  • Always read and follow the product label for specifics.
  • Spray herbicide directly onto foliage of individual plants.
  • Use spray pressures and techniques that minimize spray drift.
  • Get good coverage on the growing tips and terminal leader.
  • Spray front and back sides of the target clump to ensure adequate coverage.
  • Apply the herbicide solution at a volume that wets the crown, but minimizes runoff.

Recommended Equipment:

  • High-volume foliar – hand-held spray guns with coarse droplet nozzles.
  • Low-volume foliar – Backpack sprayers with flat or adjustable spray tips, Model 30 GunJet with rollover nozzle, Philly Foam system, Thinvert system or Radiarc sprayer mounted to a truck or skidder.
