Barricade Pre-Emergent Herbicide by Syngenta

Barricade is a selective pre-emergent herbicide by Syngenta that delivers long-lasting residual control of grassy and broadleaf weeds in established turf, garden beds, and potted plants. Trusted by turf professionals across Australia, a single application provides up to 6 months of reliable weed prevention.

Key Features

• Up to 6 Months Weed Control – One application per season keeps your lawn and garden beds weed-free for longer, reducing the need for repeated treatments.
• Wide Weed Spectrum – Controls Summer Grass, Winter Grass (Poa annua), Crab Grass, Crowsfoot Grass, Paspalum, African Lovegrass, Parramatta Grass, and many more.
• Safe on Established Turf – Binds to the top 1–2 cm of soil and stays there, creating an effective barrier without affecting turf roots below. No phytotoxicity on established plants.
• Easy-to-Use Liquid Formulation – Low odour, non-staining formula that mixes easily in a spray tank for hassle-free application.
• Flexible Application Window – Apply well before weeds germinate with added flexibility to delay wash-in for a few days if necessary.
• Exempt from Poison Scheduling – Reduces worker risk and disruption to the community.

Suitable Turf Types

Registered for use on Couch, Buffalo, Kikuyu, Zoysia, Queensland Blue Couch, Carpet Grass, Bahia Grass, Seashore Paspalum, and all established turf grass species. Also suitable for garden beds and potted plants in nurseries, public open spaces, and residential or commercial gardens.

How It Works

Barricade controls susceptible weeds by interfering with cell division in the root tips of newly germinated weeds. It binds high in the soil profile, creating a weed barrier that stops germinating seeds before they emerge, while turf roots below remain unaffected.

Application Guide

• Water Volume: Minimum 500 L/ha for optimal soil coverage
• Nozzle: Extremely coarse droplets, white 08 nozzles recommended
• Wash-in: At least 6 mm rain or irrigation within 7 days of application
