Clover in a manicured lawn is a peculiar frustration — it thrives in thin, underfed turf, blooms cheerfully, and resists common broadleaf sprays that kill dandelions overnight. The wrong herbicide either turns your grass yellow or forces you to dig every patch by hand.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I study herbicide chemistry, surfactant interactions, and label rates across dozens of formulations to separate what actually kills clover from what merely stunts it.
After analyzing active ingredients and thousands of verified owner reports, I settled on the products that consistently eliminate clover without collateral damage. This guide covers the best weed killer for clover across different lawn types, application methods, and infestation levels.
How To Choose The Best Weed Killer For Clover
Not all broadleaf herbicides touch clover. The plant’s waxy leaves and deep root system shrug off weak formulations. You need a product with the right active ingredients and application method for your lawn type and infestation size.
Focus on triclopyr and dicamba
Clover is notoriously resistant to straight 2,4-D. Formulations that combine triclopyr or dicamba with 2,4-D penetrate the leaf cuticle and translocate to the root system. Products listing triclopyr as an active ingredient typically show visual wilting within 24 hours and full kill within a week.
Match the formulation to your yard
Ready-to-use trigger or wand sprays work best for spot treating scattered clover patches on lawns under 5,000 square feet. Concentrates mixed in a pump or backpack sprayer cover large areas cost-effectively. If clover covers more than 30 percent of your lawn, a concentrate-based approach saves money and time.
Check the rainfast window
Most modern clover-targeting herbicides require only one to six hours of drying time before rain. A short rainfast window matters more in humid or rainy seasons. Products with a six-hour window give you flexibility; those claiming rainfast in one hour are ideal for unpredictable weather.

In‑Depth Reviews
1. Ortho WeedClear Lawn Weed Killer Ready-To-Use with Comfort Wand
Ortho WeedClear combines a battery-powered Comfort Wand with a selective post-emergent formula that targets clover, crabgrass, and dandelions without harming common lawn grasses — including fescues, bluegrass, and zoysia. The wand delivers a consistent spray pattern that reduces overapplication, a common issue with trigger bottles that waste product on bare soil.
Owner reports confirm the formula works on clover, but patience is required. Most users see yellowing after about a week, with full kill taking two to three weeks for established clover patches. The ready-to-use format covers roughly 10,600 square feet, making it a solid choice for suburban lawns with scattered clover.
The main trade-off is speed. Owners accustomed to fast-acting concentrates may find the wait frustrating, especially for thick clover mats. The battery wand simplifies spot treatment for users who dislike hand-pumping, though the battery compartment can feel bulky in tight corners.
What works
- Selective formula kills clover without harming cool-season turf
- Battery-powered wand eliminates hand fatigue during spot treatment
- Large container covers up to 10,600 sq ft
What doesn’t
- Kill speed is slow — may take three weeks on mature clover
- Wand battery lifespan may not cover the full tank
2. Select Source Triad TZ 4-Way Combination Herbicide
Triad TZ packs four active ingredients — 2,4-D, dicamba, triclopyr, and sulfentrazone — making it one of the most comprehensive clover killers available without a commercial applicator license. The sulfentrazone adds suppression of yellow nutsedge, a weed that often coexists with clover in compacted lawns.
User feedback consistently highlights rapid visible results: clover leaves curl and wither within 24 hours of application. Owners who previously struggled with off-the-shelf sprays report complete clover elimination after a single treatment, with grass filling bare spots within two weeks. The quart treats about 12,000 square feet at standard rates.
The concentrate requires a pump or backpack sprayer and careful mixing. The product has a strong chemical odor, and overspray can damage ornamentals. Some users report leaking bottle caps during shipping, so inspect the seal before mixing.
What works
- Four-ingredient formula kills clover in 24 hours
- Also suppresses nutsedge and wild violet
- Cost-effective for large-area treatment
What doesn’t
- Requires separate sprayer — not ready-to-use
- Strong odor; full PPE recommended during application
3. Spectracide Large Plot Weed Stop for Lawns Concentrate
Spectracide’s Large Plot formulation targets broadleaf weeds including clover, chickweed, and dandelion while leaving northern and southern lawn grasses intact. The gallon concentrate treats up to 32,000 square feet, making it the highest-coverage option in this lineup for owners of large properties.
Owner reports praise its speed on spurge and dandelion, but clover results vary more. Some users see complete kill within days, while others report needing a second application for dense clover patches. The six-hour rainfast window is reasonable, though not as tight as premium competitors.
The concentrate mixes easily in backpack or hose-end sprayers. A minority of recent buyers claim the formula changed and performs worse than previous versions. If you have heavy clover across a large lawn, the per-square-foot cost is hard to beat, but spot treaters may prefer a ready-to-use alternative.
What works
- Treats up to 32,000 sq ft per gallon — best value for large lawns
- Rainfast in six hours
- Won’t harm northern or southern grass types
What doesn’t
- Clover may require two applications
- Some reports of reduced efficacy in recent batches
4. Bonide Chickweed, Clover & Oxalis Killer Ready-to-Use
Bonide specifically names clover in its product title, and the formula backs it up with a triclopyr-and-dicamba base that penetrates waxy clover leaves effectively. The 128-ounce ready-to-use bottle covers roughly 10,000 square feet and works well on mixed broadleaf infestations where clover, chickweed, and oxalis appear together.
Owners report clover browning within three days under favorable conditions, with dandelions dying even faster. The spray is nearly odorless, which makes it more pleasant for close-to-house applications. Several users note that the included hand sprayer is mediocre for large areas and recommend decanting into a pump sprayer for better coverage.
The product is not a pre-emergent, meaning it kills existing clover but won’t prevent new seeds from germinating. A few buyers received bottles with missing or defective spray handles — check the nozzle before your first use. Overall, this is a solid mid-range option for clover-focused spot treatment.
What works
- Specifically formulated for clover, chickweed, and oxalis
- Nearly odorless; pleasant to use near patios
- Visible results in 3 days on clover
What doesn’t
- Hand sprayer is subpar for large yards
- Not a pre-emergent — won’t stop clover regrowth
5. Ortho Weed B Gon Weed Killer RTU Trigger
Ortho Weed B Gon is a compact 24-ounce trigger spray that offers a quick, no-mix solution for small lawns or targeted clover patches. The 2,4-D and dicamba blend kills 250+ broadleaf weeds and shows results in hours on sensitive species, though clover typically takes a few days to fully yellow and die.
Verified owners consistently report it kills clover without damaging surrounding grass, especially on fescue and bluegrass lawns. The trigger sprayer delivers a controlled stream that reduces drift onto flower beds — a real advantage when treating clover near garden borders. The small bottle fits under a sink or in a garage shelf.
The downsides are capacity and cost. At 24 ounces, this is the smallest volume in the lineup and works best for spot treatment on lots under 2,000 square feet. Some repeat buyers note the price has increased significantly over the years, making it less economical for heavy infestations compared to concentrates.
What works
- Kills clover and 250+ other broadleaf weeds
- Compact trigger sprayer fits small storage spaces
- Results visible within hours on many weeds
What doesn’t
- Small bottle — expensive per square foot for large lawns
- Clover may take longer than dandelion to die
Hardware & Specs Guide
Active Ingredients
The most effective clover killers contain triclopyr or dicamba as primary active ingredients. Triclopyr disrupts cell growth in broadleaf weeds, while dicamba mimics natural plant hormones to cause uncontrolled growth and death. Products with both ingredients, like Bonide’s Chickweed Clover & Oxalis Killer, offer the fastest knockdown. Straight 2,4-D products struggle with clover’s waxy cuticle and often require repeat applications.
Application Format
Ready-to-use sprays (RTU) eliminate mixing errors and are ideal for spot treating up to 10,000 square feet. Concentrates require a separate sprayer but treat 25,000 to 42,000 square feet per gallon, making them cheaper per treatment. For clover infestations covering more than 30 percent of the lawn, a concentrate mixed in a backpack sprayer provides better coverage and lower total cost.
