Plateau herbicide works during pre- and post-emergence, killing common weeds and grasses along roadsides. It targets tall, invasive grasses such as fescue and smooth bromegrass, keeping noncrop areas free of weed growth. When it's used during the fall, Plateau herbicide helps to control cheatgrass, a major source of wildfires in the West. It has an active ingredient for eradicating noxious weed species and providing long-term suppression. If other weed killers can't do the job, reach for Plateau herbicide from BASF.


How Plateau Herbicide Works

Containing imazapic as the primary ingredient, Plateau is used as a pre- and postemergent herbicide for the control of broadleaf weeds and annual and perennial grasses. Once it's sprayed onto the weed, the chemical agent quickly translocates throughout the plant, including any edible portions such as seeds and leaves. Therefore, you should never use Plateau on food crops. It destroys the weed from the inside and suppresses growth in the target area.


Where to Use Plateau

For the control and suppression of weeds and turf height, Plateau provides superior results when it's used as directed. It's labeled for use in noncrop lands, ditch banks, prairie sites and nonresidential turf. It keeps weeds controlled on petroleum tank farms, utility plant sites and highway rights of way. You can also use Plateau in grassy areas on golf courses, airports and recreational sites. However, it is not labeled for use on residential lawns.


Target Weeds

Plateau herbicide controls the toughest and most noxious weed species in noncrop areas, such as cheatgrass and tall fescue. It also controls Bahia grass, leafy spurge and bindweed on roadsides and industrial turf. Use Plateau herbicide to kill and control:

  • Johnsongrass
  • Medusahead
  • Sandbur
  • Vaseygrass
  • Houndstongue
