Getting a handle on weeds before they emerge is the key to preventing overgrowth in the spring and summer. Barricade 4FL is a pre-emergent herbicide made for stopping weeds below the soil. It controls more than 30 different broadleaf weeds and grasses throughout the season, keeping the lawn and other sites free of invasive weed growth.

How Barricade 4FL Works

Barricade works through its active ingredient, prodiamine. This chemical interferes with the weed at the cellular level, disrupting cell growth that prevents the weed from emerging and maturing. For the best results, apply it in January to stop weeds from emerging in the spring. However, it may be applied any time of year to stop new seeds from germinating and growing into weeds.

Where to Use Barricade 4FL

Barricade herbicide is labeled for use on a variety of sites, including lawns and expansive turf areas. It may also be used for pre-emergent weed control in sod nurseries, as well as on all container-, field- and landscape-grown ornamentals. Apply it around perennials and on Christmas tree farms to stop weed growth in the area.

Features and Benefits

Barricade 4FL controls a variety of weeds such as barnyardgrass, crabgrass and spurge. It prevents unwanted growth from witchgrass and other grassy weeds. When combined with a post-emergent herbicide, it provides total weed control throughout the year. Other benefits include:

  • Provides season-long weed control
  • Controls both broadleaf and grassy weeds
  • Doesn't stain surfaces
  • Great for crabgrass control
  • Stops weed growth in container ornamentals
