🌱 Spartan Herbicide: The Trusted Pre-Emergent Weed Control for Lawns

Looking for long-lasting pre-emergent weed control? Discover how Spartan Herbicide helps stop weeds before they start. Ideal for professional and home lawn care.

What Is Spartan Herbicide?

Spartan Herbicide is a powerful pre-emergent weed killer that prevents unwanted annual grasses and broadleaf weeds before they emerge. It's widely used in turf management, particularly in Australia, for its long-lasting results and reliability in both warm and cool climates.

Key Features:

• Controls winter grass (Poa annua) and other annual weeds
• Safe for use on established turf
• Provides up to 6 months of residual control
• Easy to apply with a standard sprayer

How Spartan Herbicide Works

Spartan contains the active ingredient Prodiamine, which forms a protective barrier in the soil. This stops weeds like crabgrass, winter grass, and crowsfoot from germinating and taking root.

✅ Pro Tip: Spartan does not kill existing weeds. It’s a preventative solution, best used before weed seeds germinate.

When and How to Apply Spartan Herbicide

Timing is everything with pre-emergents. Apply Spartan before the weed seeds start sprouting — ideally at the beginning of the weed’s growing season.

Ideal Application Times:

• Late summer to early autumn (for winter weeds)
• Late winter to early spring (for summer weeds)

Application Steps:

1. Mix Rate: Typically 1–2 L per hectare, or follow the product label.
2. Use a sprayer: Apply evenly over your lawn.
3. Water in: Spartan must be watered in within 7 days to activate the herbicide barrier.
4. Avoid disturbance: Don’t aerate or disturb the soil after application.

Spartan targets a broad range of common turf weeds including:

• Winter grass (Poa annua)
