Application Methods

Broadcast

Broadcast applications are ideal for treating large, open areas where target weed or brush species are scattered throughout. Depending on the product, broadcast applications can be made by ground or by air.

Best For

  • Cleaning up moderate to dense weed and brush infestations (>150 plants per acre)
  • Treating large, open areas

How-to

  • Always read and follow label directions
  • Keep ground-rig booms high enough to clear foliage and provide suitable coverage, but low enough to minimize the chance of drift
  • Calibrate equipment to ensure precise application, sound stewardship and economical use of herbicide
  • Maintain constant ground speed and sprayer pressure
  • Apply an adequate total spray volume to ensure good coverage
  • Foam markers or GPS guidance systems can help avoid skips or excessive overlaps
  • Mature brush stands require aerial application

Herbicide Recommendation

Most Corteva Agriscience Range & Pasture herbicides are labeled for broadcast applications. Visit the individual product page or consult the product specimen label for mixing and application instructions.


High-volume Foliar

High-volume foliar (leaf spray) applications can help you quickly and efficiently take out emerging brush problems before they become bigger — and more-expensive — headaches. Consider high-volume foliar for multi-stem species, such as multiflora rose, sapling trees or for protecting and maintaining valuable fence lines.

Best For

  • Controlling light to moderate brush stands (<150 plants per acre)
  • Treating small trees, vines, bushes with canes or stems, such as multiflora rose, or low-growing shrubs, such as buckbrush
  • Stopping encroaching weeds and brush around pasture perimeters or scattered across grazing areas
  • Clearing brush and/or weeds in fencelines

How-to

  • Always read and follow label directions
  • Apply directly to the target plant’s foliage
  • Spray plants from all sides until wet
  • Complete coverage is critical for success
  • Delay treatment until brush is fully leafed out in the spring and actively growing
  • Delay treatment after mowing or shredding for several weeks or even until the following season to allow adequate regrowth and improved herbicide uptake
  • Treat when the plant is healthy (not stressed by drought or other conditions)
  • To improve herbicide uptake, include 1 quart of surfactant per 100 gallons of spray mix

Low-volume Basal

Low-volume basal applications give you the ability to quickly and easily control small (less than 6 inches in diameter), emerging brush plants before they become more serious problems. Because you control only the individual plants you choose, these applications are ideal for selectively managing brush stands. Best of all, you can make these applications any time of year, as long as snow or standing water doesn’t prevent proper application.

Best For

  • Effective control of individual brush plants and small trees
  • Use on species with trunks less than 6 inches in diameter at tree base
  • Treating mild to moderate brush infestations in pastures
  • Clearing fence lines
  • Year-round treatment of woody species

How-to

  • Always read and follow label directions
  • Apply enough spray to wet the lower 15 to 20 inches of the trunk, including the root collar
  • Do not spray to the point of runoff
  • Treat any time of year, except when snow or water prevent spraying to the groundline 

Herbicide Recommendation

Remedy® Ultra herbicide or PastureGard® HL herbicide: Tank-mix with a commercial based oil (see mixing chart below).


Basal Cut-stump

When mechanically removing trees or other woody plants, it’s important you treat the stumps to prevent resprouting. Basal cut-stump applications kill the stump for good.

Best For

  • Preventing resprouts on mechanically controlled brush
  • Killing stumps for good
  • Year-round use
  • Light to moderate brush densities

How-to

  • Always read and follow label directions
  • Spray sides of stump, including any roots above the soil surface, and the outer portion of the cut surface, including the cambium ring along the inner bark
  • Thoroughly wet the stem and root collar area, but not to the point of runoff
  • Treat any time of year, as long as snow or water doesn’t prevent proper application

Herbicide Recommendation

Remedy® Ultra herbicide or PastureGard® HL herbicide: Tank-mix with a commercial basal oil or other oil-based carrier (see mixing chart below)
