5 Best Bindii Weed Killers – Safe For Buffalo, Couch & Kikuyu (Australia)

Stepping on bindii spikes in bare feet once is enough motivation to fix the problem fast. The goal: knock out bindii without scorching buffalo, couch or kikuyu. Below are the selective herbicides I use and recommend in Australian conditions, plus timing and application tips to avoid repeat outbreaks. If clover has crept in alongside bindii, see our guide to clover killers for lawns. And if you hate hand-pumping sprayers, a quality battery unit from our picks of battery-powered backpack sprayers makes uniform coverage simple.

Best selective bindii weed killers in Australia (safe for buffalo, couch & kikuyu)

1) Bow & Arrow Herbicide (Best Overall)

Why it stands out: This is the one I reach for when a lawn has a mix of bindii, creeping oxalis and clover. It’s a professional three-way formulation designed to move into the weed’s growing points while remaining selective on common warm-season turfs when applied at label rates.

Real-world use: On a 300 m² buffalo lawn in Sydney, a single pass with dye added showed clean, even coverage; bindii yellowed within a week and was gone by week three, with no bronzing of the buffalo.

• Pros: Strong on bindii at cool-season temps; high coverage per bottle; consistent on buffalo, couch, kikuyu when label rates are followed.
• Cons: Concentrate requires measuring; not a 1-day quick-burn—results build over 1–3 weeks.

Best for: Larger lawns or mixed-weed infestations where you want one pass to tidy everything up.

Avoid if: You only have a tiny patch and prefer a ready-to-use sprayer.

2) Amgrow Bin-Die Selective Lawn Weeder (Best Budget)

Why it stands out: A long-standing Aussie favourite for bindii. The formulation is designed to hit broadleaf weeds fast while remaining safe on buffalo, couch and kikuyu lawns at the correct rate.

Always read and follow the APVMA-approved label. Coverage varies by rate, weed pressure, and lawn type.

When to spray bindii in Australia (timing by season)

Bindii germinates in autumn, builds through winter, and produces painful seed heads in late spring into summer. Your best window is late autumn to early spring while the plants are small and actively growing.

• Southern states (VIC, SA, TAS): First pass late May–August; follow-up 2–4 weeks later if needed.
• Coastal NSW/WA and Adelaide: June–September works well; avoid hot, windy days.
• QLD/NT (warmer zones): Aim for the milder months; skip days above ~30°C. Early morning sprays are kinder to buffalo.

Practical tips: Don’t mow for 24–48 hours before or after spraying; you want enough leaf area to catch the herbicide. Hold off if rain is due within 6 hours (or per label). For drought-prone lawns, conditioning the soil first with a wetting agent can improve consistency; see our guide to lawn soil wetting agents.

How to choose a selective bindii killer for buffalo, couch & kikuyu

• Check lawn type on the label: Buffalo can be sensitive to the wrong actives. Choose products specifically listing buffalo safety at the recommended rate.
• Concentrate vs hose-on: Concentrates (e.g., Bow & Arrow, Bin-Die) are economical and flexible; hose-on options (e.g., Yates Buffalo PRO) are easier for beginners.
• Mixed-weed pressure: If you also have clover/oxalis, pick a multi-weed formulation. We’ve covered more choices in our clover killers guide.
• Lawn size: For 300–600 m², a concentrate usually wins on cost-per-m². For a townhouse courtyard, a hose-on is fine.
• Application gear: Uniform coverage beats over-spraying. A good battery sprayer from our best backpack sprayers list makes a visible difference.

Application tips: clean kill without harming the lawn

1. Calibrate once: Time how long it takes to comfortably walk your lawn lanes. Measure output into a jug for that time. This prevents hot spots.
2. Use a spray dye indicator: It shows where you’ve been and avoids double-ups, especially on couch. Browse lawn spray dye indicators

3. Keep pressure low and nozzle consistent: Fine to medium fan patterns stick better to bindii rosettes.
4. Don’t mix extras unless the label allows: Wetters and fertilisers can alter selectivity. If you prefer a simple one-pass tidy, consider a labelled weed & feed for buffalo.
   Compare Prices
5. Follow-up at 2–4 weeks if needed: Late-germinating bindii happens—don’t be afraid of a light second pass.

If you’re feeding separately, a broadcast spreader helps even coverage. See our professional lawn spreaders guide and our seasonal picks for spring weed & feed lawn fertilisers.

Prevention: stop next year’s bindii bloom

After you’ve cleaned up this season, keep the turf dense and stress-free. Water deeply and less often, feed lightly in spring, and keep mowing heights a touch higher on buffalo. To reduce new weed seedlings each year, consider a pre-emergent for annual grassy weeds in parallel with broadleaf control—our guide to pre-emergent timing explains how to slot it into your schedule.

FAQs: bindii weed killers in Australia

Will these products damage buffalo lawns?

All picks above are commonly used on buffalo when applied at label rates. Always check the label for buffalo safety and avoid spraying in heat or drought stress.

What month should I spray bindii?

Late autumn through winter is ideal, before prickles form. Early spring still works if you act before seed heads harden.

How long until I see results?

You’ll typically see yellowing or wilting within 3–10 days, with full control in 2–3 weeks. Dense patches can need a follow-up at 2–4 weeks.

Can I mix a wetter or fertiliser with my herbicide?

Only if the label allows. Adding unlisted products can reduce selectivity and risk turf injury.

Is hose-on as effective as concentrate?

Hose-on is easier for beginners and small lawns. Concentrates offer better value per m² and finer control on tough infestations.

What if rain hits after I spray?

Most labels require several rain-free hours. If heavy rain hits within that window, plan a light re-spray when it’s dry.

Do I mow before or after spraying?

Don’t mow for 24–48 hours before or after. You want plenty of leaf area to intercept the spray and time for absorption.

Can I spot-spray instead of doing the whole lawn?

Yes. For scattered bindii, a handheld sprayer and a dye indicator make precise spot work easy.

The bottom line

If you want fast, selective control that’s gentle on buffalo, couch and kikuyu, go concentrated with Bow & Arrow or budget-friendly Bin-Die; if you’re new to spraying, Yates Buffalo PRO hose-on keeps it simple. Feed and thicken in spring to crowd out future bindii—our guide to weed & feed fertilisers lays out the options. And if you want to upgrade your toolkit, our picks for battery backpack sprayers will save your forearms and improve coverage.
