Estate Herbicide

Overview

Estate combines three active ingredients to deliver powerful, broad-spectrum control of the toughest lawn weeds. Its low-rate formulation reduces application volume and drift risk, making it suited to residential properties where precision matters.

Active Ingredients

MCPA 300 g/L (present as the potassium salt); Clopyralid 20 g/L (present as the potassium salt); Diflufenican 15 g/L

Classification: Selective post-emergent herbicide (non-ester formulation). Safe on a range of warm- and cool-season turf species.

Controls

Estate provides effective control of persistent broadleaf weeds, particularly species that resist other herbicides.

• Bindii (Soliva sessilis)
• White Clover (Trifolium repens)
• Other broadleaf weeds

Application Rate

Area to Treat	Product Dose	Water	Notes
100 m²	50 mL	2–5 L	Spray evenly
1,000 m²	500 mL	20–50 L	Low-rate formulation

How to Apply

1. Choose a calm, dry day with temperatures between 10–25°C.
2. Apply when weeds are actively growing, typically at the 3–6 leaf stage for maximum effectiveness.
3. Mix Estate with water according to the rate above. Use a pressure sprayer for even coverage.
4. Spray all weed foliage until wet but not dripping. Complete leaf coverage is essential for herbicide uptake.
5. Avoid mowing during the 3 to 4 days preceding or following treatment.
6. Complete weed death may take up to 6 weeks. Faster results can be expected on smaller weeds.

Important Information

• Timing: Apply spring through autumn when weeds are actively growing. Avoid winter application when growth is minimal.
• Rain: Do not use if rain is expected within 4 hours. This governs when to spray — the label sets no drying time after application.
• Mowing: Avoid mowing during the 3 to 4 days preceding or following treatment.
• Grass types: Safe on Buffalo, Kikuyu, and other warm-season turf. Test a small area first on cool-season varieties.
• Drift risk: Non-ester formulation reduces volatility and drift. Apply on calm days to protect nearby sensitive plants.
• Repeat applications: Most weeds require only one application. Re-treat only if regrowth warrants it.
• Over-seeding: Due to residual effects of diflufenican, over-seeding treated areas within 3 months of application may inhibit establishment of the turf grass.
