BARRICADE is a selective pre-emergent herbicide that provides residual control of weeds in established turf, garden beds and potted plants. BARRICADE controls susceptible weeds by interfering with cell division in the root tips of newly germinated weeds. BARRICADE Herbicide controls a wide range of pre-emergent grassy weeds. You can trust BARRICADE to last for up to 6 months so your application window is more flexible. BARRICADE binds high in the soil profile ensuring turf roots below the barrier are not affected and your turf stays in prime condition.


  • Easy to use liquid pre-emergent herbicide that controls a wide range of grassy weeds, including African Lovegrass, Parramatta Grass, Summer Grass, Crab Grass, Crowsfoot Grass and Winter Grass
  • Up to six months of control with a single application per season.
  • Safe on established plants with no phytotoxicity
  • Low odour, non-staining formulation
  • Binds to the top 1-2 cm of soil, holds tightly and stays there, creating an effective longer-term barrier to weeds


  • Flexible application window – well before weeds germinate and with the added flexibility to delay wash-in for a few days if necessary
  • Allows for fewer herbicide applications, which creates efficiencies in productivity and fewer weed management interventions per season
  • Exempt from poison scheduling, which reduces worker risk and disruption to the community


Application rate: 10-40mL/100sqm

Water in thoroughly after application. 1L Barricade can cover up to 2500-10000sqm depending on application rate.

Application should be prior to germination of the weeds.

Barricade is best applied with a backpack or handheld sprayer to ensure even application. Sprayer calibration is recommended.

  • Tank mixing

Add the required quantity of BARRICADE directly to a spray tank containing 2/3 of the required spray volume. Add the rest of the water and ensure the mix is thoroughly agitated before application.

If mixing with Monument Liquid, add Monument Liquid and a non-ionic surfactant after BARRICADE, then add the rest of the water and ensure the mix is thoroughly agitated before application. Refer to Monument Liquid label for specific mixing instructions.

  • Water volume

Ensure product placement as close to soil surface as possible. Total application volume should not be lower than 500 L/ha. Use extremely coarse droplets and white 08 nozzles. Wash in with at least 6 mm rain or irrigation within 7 days of application.
