Say Goodbye to Winter Weeds and Lawn Prickles with Syngenta's Game-Changing New Releases

Winter Weeds Got You Down? It’s Time to Fight Back.

If your beautiful lawn turns into a battlefield every winter, you’re not alone. We’ve all been there—dodging bindii prickles, waging war on clover patches, and wondering why the weeds always seem to win.

But now, with Syngenta’s latest innovations—Estate Broadleaf Herbicide and Barricade Pre-Emergent—there’s a smarter, easier, and more effective way to prevent winter weeds before they even start and eliminate broadleaf nasties like bindii and clover with precision.

At Green Lawn Supplies, we’re proud to stock Syngenta’s cutting-edge turf solutions to help Aussie homeowners, greenkeepers, and landscapers keep their lawns healthy, weed-free, and family-friendly all year round.

Let’s break down how these two products can transform your lawn care routine—and help you answer those popular search questions like:

• “How to prevent winter weeds?”

• “Stop prickles in my lawn?”

• “What’s the best pre-emergent herbicide in Australia?”

• “How do I get rid of clover in my turf?”

Meet Syngenta Estate: Your Broadleaf Weed Buster

Target Weeds: Bindii, clover, creeping oxalis, cudweed, plantain, thistles & more
Use On: Couch, kikuyu, buffalo (excluding ST varieties), ryegrass & fescue lawns

Why Estate Broadleaf Herbicide?

Estate Broadleaf Herbicide is a premium post-emergent herbicide formulated to take on the most common and stubborn broadleaf weeds in Australian lawns—especially those that show up as temperatures drop.

If you’ve ever walked barefoot across your lawn and stepped on a spiky bindii, you already know why this matters.

Key Benefits of Estate:

• Fast-acting formula with visible results within days

• Excellent selectivity – safe on most common turf types

• Combines two proven active ingredients: MCPA and Dicamba

• Controls a wide spectrum of broadleaf weeds without harming your lawn

• Perfect for use in winter and early spring when broadleaf weeds thrive

Estate is ideal for blanket spraying to kill all your weeds, depending on your lawn’s condition. It's especially effective when applied during the early stages of weed growth—so don’t wait until the weeds take over.

👉 Tip: For best results, apply Estate when weeds are actively growing and the earlier the better. Once prickles have formed its a lot harder to get rid of the prickles in your lawn.

What About Preventing Weeds Before They Appear? That’s Where Barricade Comes In.

Target Weeds: Winter grass, summer grass, crowsfoot, chickweed, oxalis, and more
Use On: Couch, kikuyu, buffalo, zoysia, ryegrass, bentgrass, fescue

The Power of Pre-Emergent Weed Control

While Estate kills existing broadleaf weeds, Syngenta Barricade stops weeds before they even sprout. That’s the secret weapon most lawn lovers and turf professionals rely on to keep their lawn pristine throughout winter and beyond.

Barricade contains prodiamine, a highly effective pre-emergent herbicide that creates an invisible barrier at the soil level to prevent seeds from germinating.

This means:

• No new weeds popping up

• No bindii prickles getting started

• No more constant weed-spraying battles all season long

Why Use Barricade?

• Provides up to 6 months of control against winter and summer weed germination

• Reduces the need for reactive spraying

• Works beautifully in tandem with Estate for a full-circle lawn defence plan

• Super safe on established lawns when used as directed

👉 Pro tip: Apply Barricade in late summer to early autumn (Feb–April) before weeds start to germinate, and reapply as needed based on soil disturbance or weather conditions.

Real Talk: Why Lawn Prickles Are More Than Just a Nuisance

Lawn prickles, most commonly caused by bindii, are the number one complaint we hear from homeowners during autumn, winter and even into spring. These tiny, spiky seed heads hurt bare feet, pets, and children—and once they’ve taken hold, they spread fast.

Estate + Barricade is the ultimate one-two punch to prevent prickles altogether and kill any that slip through.

Scenario Example:

Sarah from Newcastle has a lush buffalo lawn but every winter, bindii takes over. Her kids stop playing outside, and her dog refuses to go on the grass. Last year she tried pulling them out by hand—which was a big task. This year, she applied Barricade in early March and followed up with Estate in mid-May. No bindii, no drama, and the kids are back outside enjoying the lawn.

Top Questions We Get About Lawn Weed Control – Answered
