Broad-Spectrum Weed Control Made Easy
One Application For Season-Long Control
BARRICADE is a selective pre-emergent herbicide that provides residual control of weeds in established in lawns, garden beds and potted plants. It controls susceptible weeds by interfering with cell division in the root tips of newly germinated weeds.
Product details
- Available in 1 litre or 5 litres.
Uses
- Up to six months control with a single application per season.
- Binds to the top 1-2 cm of soil, holds tightly and stays there creating an effective longer-term barrier to weeds.
- Option to tank mix with Glyphosate to treat gravel pathways, and fence lines offering knock-down and pre-emergent in one application for up to 6 months of weed control.
Features and Benefits
- Safe on established plants with no phytotoxicity.
- Low odour, non-staining formulation.
- The roots below the barrier are not affected and your lawn and plants stay in prime condition.
- 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 and less weed management interventions per season.
- Exempt from poison scheduling.
