Vanquish herbicide kills broadleaf weeds, brush and woody plants on lawns, golf courses and other grassy sites. It contains an easily absorbed ingredient that circulates through the weeds and causes them to collapse. You can use it as a spot treatment or a wide application to cover an entire ornamental landscape or a pasture. It works effectively and provides a selective way to treat and control weeds and brush on protected sites. For enhanced weed control, choose Vanquish weed killer.

How Vanquish Herbicide Works

With 56 percent dicamba as the main ingredient, Vanquish provides successful weed control of more than 200 broadleaf weeds, brush and vines. Once you apply the product to the target area, the weeds absorb the active ingredient and translocate it throughout their system. The dicamba starts to work and collapse the weed, causing death and helping desirable plants to grow without competing for nutrients. 

Where to Use Vanquish Weed Killer

Vanquish has a wide range of application uses and controls weeds on established turfgrasses and lawns. It helps to keep golf course greens, fairways and tees free of invasive weeds and controls excessive growth on roadsides and rights of way. You can also target weeds and brush along nonirrigation ditches, fence rows and railroads. Other areas for use include:

  • Recreational areas
  • Campgrounds
  • Wildlife openings and habitats
  • Forestry sites
  • Parking and storage areas
  • Pipelines and tank farms

Vanquish herbicide kills and controls annuals, biennials and perennials such as amaranth, dwarf mallow and stinging nettle. It also targets lamb's quarters, black nightshade and Canada thistle. Use Vanquish weed killer to control the following weeds and woody plants:
