Protect Ornamentals with Powerful Weed Control

When it comes to ornamental production, weeds are more than just an unsightly nuisance – they also threaten the health of nursery plants by stealing valuable nutrients. Following a comprehensive weed management program including cultural practices as well as pre- and post-emergent herbicides is essential for preventing and controlling some of the most challenging weed species.

Barricade® 4FL herbicide and Fusilade® II herbicide quickly tackle various weed species while being safe for ornamental plants and shrubs.

As a pre-emergent herbicide, Barricade 4FL offers:

  • Low water solubility to keep the herbicide from moving.
    • It stays in the top 0.5 inch of the soil, minimizing effects on the roots of nearby plants and trees.
  • The flexibility to be sprayed over the top of newly transplanted and established ornamentals grown in beds or containers.
  • A low odor, non-staining formulation, which reduces equipment and plant clean-up.
  • An excellent tank-mix partner with Pennant Magnum® herbicide for broader spectrum control.

As a selective post-emergent herbicide, Fusilade II features:

  • Broad-spectrum control of many annual and perennial grassy weeds.
  • Selective grass control that is rainfast one hour after application.
  • Translocation to the meristematic regions of shoots, roots, rhizomes, stolons and growing points of treated grass weeds.
  • The ability to stop grassy weed growth soon after application.
  • Application as a directed spray to minimize potential phytotoxicity.
  • Safety on a wide variety of ornamentals in many turf and landscape environments.
