Barricade is a pre emergent herbicide for grasses and broadleaf weeds including winter grass. Safe to use on all lawn varieties.

Categories: ,



Barricade is a selective pre-emergent herbicide that provides residual control of weeds in established turf, garden beds and potted plants. Importantly it breaks the germination cycle of Poa annua (winter grass).

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.

Why Use

  • Barricade provides up to 6 month protection from weeds, even under mulch.
  • Exemption from poison scheduling, which reduces worker risk and disruption to the community
  • Flexible application window – well before weeds germinate, allowing you to target more weed varieties with one application.
  • Low odour, non-staining formulation with the flexibility to delay wash-in for a few days if necessary
