A clover patch doesn’t just ruin the look of a lawn — it spreads, chokes out the grass you actually want, and makes every barefoot step feel wrong. The challenge is finding a spray that wipes out clover completely without turning your Kentucky bluegrass or fescue yellow. The right formula hits the broadleaf weed but leaves your turf intact, saving you from a yard of brown spots.

How To Choose The Best Herbicide For Clover
Clover spreads low and fast, so you need a selective post-emergent herbicide — a spray that targets broadleaf weeds but leaves grass species alone. The active ingredients matter most. Look for formulas built around Dicamba, Triclopyr, or 2,4-D, because these penetrate clover’s waxy leaf surface and travel down to the root system. A contact spray that just burns the tops will have clover bouncing back in days.
Active Ingredients That Work
The three heavy hitters for clover are Triclopyr, Dicamba, and 2,4-D. Triclopyr is especially strong on clover and oxalis because it mimics a plant growth hormone, causing the weed to grow itself to death from the inside. Dicamba moves through the plant’s vascular system, so it catches hidden roots. A combination of all three — called a “three-way” or “four-way” herbicide — gives you the broadest kill. Single-ingredient sprays often leave tougher weeds twisting but alive.
Liquid Form: Concentrate vs. Ready-to-Use
Concentrates let you mix only what you need, stretch the bottle across huge lawns, and often save money per square foot. A 1-gallon concentrate can treat 32,000 square feet or more, depending on the label rate. Ready-to-use sprays are simpler — open, aim, and pull the trigger — but they cost more per spray and run out fast on a full-yard infestation. If you have a small patch or just want to spot-treat, a ready-to-use trigger or wand is fine. For widespread clover, the concentrate route is cheaper in the long run.
Rainfast Timing and Temperature
Most clover killers need about 3 to 6 hours of dry weather after application. Rain within that window washes the chemical off the leaf before it can absorb. Temperature also affects speed — these herbicides work best when weeds are actively growing, typically between 45°F and 90°F. Spraying when it is too cold or too hot slows uptake and leaves clover standing. Check the label for your specific grass type too; some formulas are safe on tall fescue and Bermuda but not on St. Augustine or centipede.

In‑Depth Reviews
1. SpeedZone EW Lawn Weed Killer
The pro-grade formula that curls clover leaves within hours without wrecking your grass.
You see results within hours (not days) because the SpeedZone EW concentrated liquid uses a fast-penetrating mix of four active ingredients — 2,4-D, Dicamba, Carfentrazone-ethyl, and Mecoprop-p — to control 90+ listed weeds, including white clover, dandelion, and ground ivy. It works even in cooler spring temperatures, so you are not stuck waiting for a warm streak. You mix just 1.5 fl oz in 0.5 to 1 gallon of water to treat 1000 sq ft on cool-season grasses, and it becomes rainfast (resistant to being washed off by rain) in as little as 3 hours, meaning a passing shower won’t ruin your effort.
Buyers report that weeds curl and brown within two days, with one reviewer noting it killed all weeds across a half-acre yard. A small trade-off: the bottle does not include a measuring cup (the cap holds roughly 0.2 fl oz), so you need a separate measuring tool. Compared to the slower-acting Ortho WeedClear wand, this concentrate delivers noticeably faster wilting — a big advantage when you want to see progress before the weekend is over.
The product is labeled for Kentucky bluegrass, perennial ryegrass, tall fescue, Bermudagrass, and zoysiagrass. However, some buyers mention mixed results on recurring spurge, with reappearance within two months after an initial kill.
What stands out
- Visible results within hours — weeds curl and brown in about 2 days
- Rainfast in as little as 3 hours, so weather worries are minimal
- Works well in cool weather, giving you a wider spray window in spring and fall
The downsides
- No measuring cup included; you need your own to mix accurately
- Spurge may reappear within 2 months after treatment
Grab it if: you want the fastest wilting possible and have a sprayer on hand — the SpeedZone EW is the closest thing to a professional lawn-care result at a homeowner price.
Think twice if: you prefer a ready-to-use bottle with no mixing, or you are battling a heavy spurge infestation that may need a different active blend.
2. Select Source Triad TZ 4-Way Herbicide
The four-ingredient cocktail that tackles clover and velvetleaf where weaker sprays stall.
The Triad TZ packs four active ingredients — 2,4-D, Dicamba, Triclopyr, and Sulfentrazone — making it one of the broadest-spectrum selective herbicides you can buy without a license. That mixture is designed for tough broadleaf weeds like white clover, wild violet, ground ivy, and Virginia buttonweed, and it is also labeled for suppressing yellow nutsedge. The 32 fl oz bottle is a concentrate, so you mix it with water in a pump sprayer and apply to residential lawns, athletic fields, or golf courses.
Owners mention that it killed dandelions and clover in about a month, with visible wilting noticeable the very next day. One reviewer noted that clover grew twisted stems before vanishing entirely, and the bare spots filled in with grass without any damage to the turf. The downside: the product has a strong odor during application, so wear gloves and a mask.
This one outguns the Ortho Weed B Gon RTU (24 fl oz, trigger spray) by a wide margin in both ingredient depth and coverage — the Triad TZ’s 32 fl oz concentrate stretches much further than a ready-to-use bottle, making it the smarter buy if you have a medium to large lawn.
Why it wins
- Four active ingredients cover a wider range of tough broadleaf weeds
- Visible wilting the next day; full kill in about a month
- Safe on lawns — clover died without harming surrounding grass
What to watch
- Strong chemical odor requires a mask and gloves during mixing
- Some packaging leakage reported by buyers
Reach for this if: you have a mix of clover, dandelions, wild violet, or ground ivy — the four-way formula handles them all without separate bottles.
Look elsewhere if: you want a completely odorless spray or prefer a ready-to-use bottle with zero mixing.
3. Ortho WeedClear Lawn Weed Killer Ready-To-Use with Comfort Wand
The grab-and-go wand that makes spot-spraying clover almost as easy as watering plants.
If you hate mixing chemicals and just want to spray clover patches directly, this Ortho WeedClear comes as a 1.33 gallon container with a battery-powered Comfort Wand that delivers a consistent spray stream with no pumping. It is ready-to-use — no measuring, no pouring — and targets a wide range of lawn weeds including crabgrass, dandelion, clover, chickweed, and creeping charlie down to the root. You use it when weeds are young and actively growing, with temperatures between 45°F and 90°F.
Customers note it is effective but slow — one buyer mentioned it kills thistle and prickly weeds in about a month without harming the surrounding grass. The battery sprayer is intuitive, and the 170.24 fl oz container gives you plenty of coverage for spot-treating a typical yard. The trade-off: some recent batches reportedly had no smell and did not yellow weeds at all, a risk with any consumer-grade product. Unlike the SpeedZone EW, which shows results within hours, this wand takes weeks, so it suits patient regular maintenance.
At 195.68 ounces, this is significantly heavier than a 24-ounce trigger bottle like the Ortho Weed B Gon — you are trading portability for volume and wand convenience.
What makes it easy
- Battery-powered wand sprays without pumping or mixing
- Ready-to-use formula — open the cap and pull the trigger
- Safe on multiple grass types: Bermuda, fescue, bluegrass, ryegrass, zoysia
The trade-offs
- Kills slowly — expect up to a month for full results on tough weeds
- Some 2025 batches reported as ineffective with no visible reaction
Best for: homeowners who want a no-mix, no-fuss wand and are okay waiting a few weeks for clover to die.
skip it if: you need fast results or a consistent batch — the occasional dud bottle makes it a gamble for large infestations.
4. Liquid Harvest Lawn Weed Killer Concentrate, 1 Gallon
The gallon jug that stretches for years across a big lawn without the chemical stench.
This 1-gallon concentrate from Liquid Harvest contains a three-way active mix of 30.89% 2,4-D, 8.23% MCPA, and 2.77% Dicamba, giving you serious broadleaf firepower in a bottle that will last most homeowners multiple seasons. You mix 0.67 to 1.5 fl oz per gallon of water to cover 1,000 sq ft, so a single gallon treats over 80,000 square feet at the light rate. The low-odor formulation is a real plus if you have ever winced while spraying traditional herbicides around your property.
Reviewers point out that crabgrass and dandelions start whitening noticeably after four days, with the rest of the lawn staying healthy. One owner reported that the grass turned slightly yellow briefly before recovering, but overall satisfaction was high. The catch: it is not a one-spray miracle. Reviews note that it kills about 80% of common broadleaf weeds within a week, but mature clover and ground ivy may need a second spot treatment. Compared to the SpeedZone EW, this one trades a little speed for a much larger total volume at a lower per-ounce cost.
At 9 pounds, this bottle is heavier than the Bonide 128 oz spray (8 pounds), but the concentrate formulation means you are buying active ingredients, not water weight.
Biggest advantages
- 1-gallon concentrate provides massive coverage — mix only what you need
- Low-odor formula makes application much more pleasant
- Visible whitening of broadleaf weeds in about 4 days
Limitations
- Not a complete wipeout in one go — mature clover may need a second pass
- Can temporarily yellow grass if over-applied
Ideal for: anyone with a large lawn who wants a low-odor concentrate that goes far and does not require monthly re-buying.
Not for: those who expect a single application to erase every weed — this works best as part of a regular maintenance schedule.
5. Bonide Chickweed, Clover & Oxalis Killer, 128 oz Ready-to-Use
The name-says-it-all spray that targets clover and oxalis before they take hold.
This Bonide product is built around two active ingredients: Dicamba and Triclopyr — a combination that hits clover, chickweed, and oxalis harder than a basic 2,4-D-only spray. The 128 oz bottle is ready-to-use, so you just attach a hose or pour it into a pump sprayer and go. One customer observed it kills dandelions in a single spray, and at the concentrate rate, a pint covers about 5,000 square feet. You must avoid mowing for two days before and after application to let the chemical fully absorb into the leaves.
Shoppers say seeing weeds start dying by the next day, with full results within a week. However, not every experience is the same — one reviewer sprayed clover heavily and saw only slight browning on the top leaves, with no wilting or death. That inconsistency seems tied to how mature the clover is; young active growth dies fast, while thick established patches may resist. The hand sprayer included with the bottle also gets complaints for being awkward on larger lawns — a separate pump sprayer is a smarter move.
At 8 pounds, this is 1 pound lighter than the Spectracide 1-gallon concentrate (9 pounds), but keep in mind it is ready-to-use, so the 128 fl oz goes faster than a concentrated jug.
Strengths
- Dicamba + Triclopyr combo is specifically strong on clover and oxalis
- Ready-to-use — no mixing required, just spray directly
- Many buyers see dead weeds by the next morning
Weaknesses
- Can fail on thick, mature clover patches — results vary
- Included hand sprayer is poor for large lawns; buy a pump sprayer separately
Choose this if: you have mostly young clover and chickweed and want a ready-to-use bottle that keeps it simple.
Pass if: you are facing mature, well-established clover or need to cover a large area — the ready-to-use format runs out fast against heavy infestations.
6. Spectracide Large Plot Weed Stop for Lawns Concentrate, 1 Gallon
The bulk concentrate that treats an entire acre of lawn while staying affordable.
This Spectracide concentrate is built for big jobs. A single 1-gallon bottle treats up to 32,000 square feet of northern grasses or 42,500 square feet of southern grasses — enough to cover a large suburban lot from fence to fence. It kills clover, dandelion, chickweed, and more than 200 types of broadleaf weeds as listed, and it is rainproof just 6 hours after application, so a sudden afternoon shower will not waste your work. The liquid mixes easily in a pump sprayer and spreads well, keeping your lawn healthy while the weeds curl.
Buyers report fast results on dollar weed, chickweed, and nutsedge. However, one user highlighted it was slow-acting and ineffective on tough fuzzy rosette weeds and foxtails, requiring a third application. The label says “see results in hours,” but not every weed reacts that quickly — clover may take longer. The 128 fl oz volume is identical to the Liquid Harvest gallon, but the active ingredient blend differs, so your results will vary depending on which weeds dominate your yard.
It weighs 9 pounds, which is the same as the Liquid Harvest concentrate (9 pounds) and 1 pound heavier than the Bonide ready-to-use spray (8 pounds).
Why go large
- Treats 32,000 sq ft — ideal for large lawns and rural properties
- Rainproof in 6 hours, reducing weather-related setbacks
- Mixes easily and covers evenly without leaving dead patches
Watch out for
- Slow on certain tough weeds like fuzzy rosette varieties and foxtails
- May need a third application for stubborn broadleaf weeds
Best for: large-lot owners who mix their own spray and want the cheapest cost per square foot.
Not ideal if: you have a heavy infestation of foxtails or fuzzy rosette weeds — those may survive the first two passes.
7. Ortho Weed B Gon Weed Killer, 24oz, RTU Trigger
The small trigger sprayer that handles a weekend’s worth of clover in minutes.
The Ortho Weed B Gon is a ready-to-use trigger sprayer — 24 fl oz of liquid that kills dandelions, clover, and more than 250 listed weeds down to the root without harming the lawn when used as directed. You simply point the nozzle at each weed, pull the trigger, and watch results in hours. It is the simplest product in this lineup and requires zero setup: no mixing, no wand battery, no measuring cup.
Owners mention “seeing great results killing clover and other weeds without killing the grass,” which is exactly what you want from a selective spray. The formula absorbs quickly, so you can see the weed start to curl within the same day. But at 24 fl oz, the bottle is small — you will cover maybe a few hundred square feet before it runs dry, making it impractical for full-yard invasions. The 24-ounce weight is dramatically lighter than the 195.68-ounce Ortho WeedClear wand, so you can carry it one-handed without fatigue.
Compared to the Spectracide concentrate that treats 32,000 sq ft, this is strictly for small patches and spot-spraying. The price per ounce is higher, but the convenience is class-leading for a quick fix.
What works
- Ready to spray right from the start — no mixing or equipment needed
- Kills clover and dandelions without killing grass, per buyer reports
- Results visible in hours, so you see progress fast
Shortcomings
- 24 fl oz runs out quickly — not suitable for large lawns
- Concentrate alternatives cost far less per square foot
Excellent for: the casual homeowner with a small lawn or a few clover patches who wants a trigger-and-done solution.
Better options exist if: you are tackling a full yard of clover — the concentrate picks above will save you money and trips to the store.
Understanding the Specs
Active Ingredients: 2,4-D, Dicamba, Triclopyr
These three are the power players behind almost every selective herbicide on the market. 2,4-D is a synthetic auxin that makes broadleaf weeds grow uncontrollably until they die. Dicamba moves through the plant’s vascular system to kill the underground root mass. Triclopyr is especially effective on woody or waxy-leaf weeds like clover and oxalis because it penetrates that tough outer layer. A product that combines all three covers more weed species and gives you a wider spray window.
Liquid Volume vs. Concentrate
Liquid volume measures the total amount in the bottle. But what really matters is whether it is a concentrate or ready-to-use. A 128 fl oz concentrate (like the Spectracide or Liquid Harvest bottles) treats tens of thousands of square feet because you dilute it with water. A 128 fl oz ready-to-use bottle (like the Bonide spray) covers far less ground because it is already diluted. Always check if the product is marked “concentrate” or “RTU” (ready-to-use) before comparing bottle sizes — the numbers mean very different things for how far the product goes.
Coverage Rate (Square Feet)
This tells you how much area the product will treat when mixed and applied according to the label. For example, the Spectracide Large Plot concentrate is listed at 32,000 square feet — that is about three-quarters of an acre. The Liquid Harvest concentrate lists a mixing rate of 1.5 oz per 1,000 sq ft, so you can calculate coverage yourself. Ready-to-use sprays rarely list a coverage number because it depends on how heavily you spray each weed. If you have a large lawn, prioritize a product that provides a coverage spec so you know exactly how much to buy.
Rainfast Window
This is the amount of dry time the herbicide needs after spraying before rain or irrigation will wash it off. A shorter rainfast window is better because it gives you more flexibility. The SpeedZone EW is rainfast in 3 hours — excellent for unpredictable weather. The Spectracide concentrate takes about 6 hours. If you spray and it rains within the window, the chemical never properly absorbs into the weed leaf, and the application is wasted. Always check the forecast before spraying.
