Barricade Herbicide 

Preventative control of weeds before weed germination in established lawns & turf, garden beds.

  • Long lasting preventative weed control for up to 6 months
  • Can be used in a variety of situations
  • Controls weeds before they become a problem

Apply BARRICADE® Pre-Emergent Herbicide before weed germination for preventative control of up to 6 months. Apply in early spring (summer weeds) or late summer to early autumn for Winter Grass. BARRICADE® Pre-Emergent Herbicide does not control weeds that have already germinated; therefore, a post-emergent herbicide should be applied to remove these weeds.

An effective method used by professional turf managers to prevent weeds before they become an issue!

Key Features

    • 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 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 less herbicide applications which creates efficiencies in productivity and less weed management interventions per season 
    • Exempt from poison scheduling which reduces worker risk and disruption to the community

Frequently Asked Questions

What is Barricade Herbicide used for?

Barricade is a pre-emergent herbicide used to prevent the germination of winter grass, ryegrass, clover, bindii, oxalis, and other broadleaf and grass weeds in established lawns and gardens. It is applied before weed seeds emerge, providing season-long weed prevention.

What weeds does Barricade prevent?

Barricade is effective against winter grass (Poa annua), ryegrass, clover, oxalis, bindii, capeweed, plantain, and other common lawn weeds. It works by inhibiting seed germination, preventing weeds from establishing in lawns and gardens.

Can Barricade be used with surfactants?

Barricade is a pre-emergent, so it is usually applied alone for best results. Mixing with a surfactant is not required.

How long does Barricade last in the lawn?

Barricade provides residual control for up to 6 months, depending on rainfall, irrigation, and soil type. Follow-up applications may be needed to maintain year-round weed prevention.

When is the best time to apply Barricade?

Apply Barricade before weed seeds germinate, which in most Australian regions is:

Autumn: for winter grass and broadleaf weed prevention
Spring: for summer annual weed prevention

Can Barricade control existing weeds?

No, Barricade is a pre-emergent herbicide, meaning it prevents new weed seeds from germinating but does not kill established weeds. For existing weeds, a post-emergent herbicide like Odessa, Monument, Bow and Arrow or ProForce Duke should be used.

How does Barricade work?

Barricade works by creating a chemical barrier in the top layer of soil that prevents weed seeds from developing into seedlings, effectively stopping germination and weed establishment before they emerge.

Why use Barricade instead of a post-emergent herbicide?

Pre-emergent herbicides like Barricade are ideal for preventing weeds before they appear, reducing the need for repeated post-emergent sprays, saving time, and helping maintain a healthy, weed-free lawn throughout the season.
