You want a green lawn, not a science experiment. The quickest win is picking a selective herbicide that kills broadleaf weeds (dandelions, clover, creeping charlie) while leaving your grass untouched. The real difference between these nine products is the active ingredient, the weed they target, and if you want a ready-to-spray bottle or a mix-it-yourself concentrate.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Compare the strongest selective herbicides for lawns by coverage, target weeds, and if you need a concentrate or a ready spray bottle.
Our Picks at a Glance
How To Choose The Best Selective Herbicides For Lawns
Selective doesn’t mean weak—it means the product targets the weed’s biology while leaving your turf grass’s biology alone. Match the active ingredient to the specific weed plague in your yard.
Match the Active Ingredient to Your Weed
The most common active ingredients are 2,4-D, Dicamba, and Mecoprop (often blended as “Trimec”) for broadleaf weeds, and Quinclorac for crabgrass. If your enemy is creeping charlie (ground ivy), look for Triclopyr or Clopyralid. If nutsedge is the problem, you want Halosulfuron-methyl.
Choose Between Concentrate and Ready-to-Use
Ready-to-use sprays are the easiest route—no mixing, just spray the weeds. Concentrates cost less per treatment and cover more ground, but require correct mixing and a sprayer. The trade-off is convenience versus cost and coverage.

In‑Depth Reviews
1. Fertilome (10525) Weed Free Zone Broadleaf Weed Killer Concentrate
Our pick — 4.5★ from 998 verified ratings; the strongest balance of quality and price.
The creeping-charlie killer that puts the gold standard in your sprayer.
What wins people over is the sheer knockout power on the weeds other products dodge. It controls over 80 broadleaf weeds — from Clover and Spurge to Chickweed and Thistle — and the reviews sum it up: “This product sets the gold standard as the ONLY product that kills creeping charlie overnight.”
It’s safe on the turf you actually want, listed as safe for Kentucky Bluegrass, Bermudagrass, Bahiagrass, and Zoysiagrass. The 32-ounce concentrate means you mix your own rate, and while the instructions suggest a certain dose, several owners found they needed nearly double strength for stubborn clover — a little testing goes a long way.
Spray it when broadleaf weeds are young and actively growing, spring, summer, or fall. Evidence of injury shows within hours, and early-spring users report sprayed areas wilting or dead within five days, even after a rain.
Why It Wins Lawns
- Kills creeping charlie where other products fail
- Safe on four major turf grass types
- Visible injury to weeds within hours
- Controls 80+ listed broadleaf weeds
What To Expect
- The label rate may run too weak — owners often double it
- Price runs high for a 32-oz bottle
- Occasional leakage reports in transit
Reach for it if: Your lawn is losing the battle to creeping charlie or a mix of tough broadleafs and you want one concentrate that covers most of the list.
Think twice if: You want a grab-and-spray bottle — this one requires mixing.
2. Ortho Weed B Gon Weed Killer, 24oz, RTU Trigger
A trigger sprayer you carry around the yard for instant clover strikes.
This is the no-mixing, no-sprayer route: a 24-ounce trigger bottle that kills dandelions, clover, and 250+ listed broadleaf weeds down to the root. The ease of use is the headline—pull the trigger and treat the weed in seconds, with reviewers noting great results killing clover without harming the grass.
That said, effectiveness gets mixed feedback. Some owners see it kill weeds quickly, while others report it doesn’t kill everything on the first pass — so treat this as a spot-spray maintenance tool, not a full-lawn overhaul.
The manufacturer says results show in hours, but a word of caution from the reviews: it’s a chemical, so gloves and a mask are smart while you spray.
The Easy Wins
- No mixing, no sprayer needed
- Kills 250+ listed weeds to the root
- Guaranteed not to harm the lawn when used as directed
- Results appear in hours
Keep In Mind
- Results vary — some weeds need a second dose
- 24 oz goes fast on a large yard
- Wear gloves and a mask while applying
Best as a: Quick weekly spot-treat companion for clover, dandelion, and chickweed on a small-to-mid lawn.
Not ideal as: A broadcast treatment for a full yard takeover.
3. Southern Ag Lawn Weed Killer with Trimec, 32oz
A patented three-way blend that wipes clover without touching your turf.
Built on a patented combination of three proven weed killers, this is the broad-coverage value play. A single 32-ounce bottle covers 5,000 square feet, and it’s labeled for use on 9 turf types — so it’s a safe first choice for most home lawns.
In practice, a dandelion invasion was gone in two weeks with no harm to the lawn, and clover and other weeds wiped out without damage when applied through an end-of-hose sprayer. The catch: it’s not great with clover for some owners, and weeds can return fast, needing reapplication every few weeks rather than a season-long solution.
Owners also note that pairing it with a surfactant (a spreader-sticker that helps the chemical cling to leaves) boosts performance, and one user finally won their onion-grass battle with Trimec plus surfactant in a week.
The Value Case
- One bottle covers 5,000 sq ft
- Safe on 9 turf types
- Less expensive than many alternatives
- No smell, easy to apply
Know Before You Spray
- Clover control can be inconsistent
- Weeds may return quickly, needing reapps
- A surfactant improves results on tough weeds
Grab it if: You want the biggest coverage per bottle at a budget-friendly price and need a general broadleaf fix.
skip it if: Your yard is all clover — you may need the Fertilome or a dedicated clover product.
4. Atticus Empero Q-Pak Nutsedge Killer (2 Pack)
The targeted nutsedge killer that travels to the root tubers.
If your lawn has nutsedge (nut grass), most general weed killers won’t cut it. This one is formulated with 5% halosulfuron-methyl, the active ingredient pros trust most for nutsedge — and it travels down to the root system tubers for a top-to-bottom kill.
The format is the standout convenience: each packet is pre-measured and pre-mixed with a surfactant. Add one packet to your sprayer, mix with one gallon of water, and you’re ready — no measuring, no separate surfactant.
It’s gentle on most established turf, including bluegrass, fescue, Bermudagrass, and zoysia. Buyers report nutgrass turning yellow in 24 hours, though full death takes patience — up to two weeks per round, and established nutsedge may need three applications before the tuberous roots let go.
Why It Works
- Targets nutsedge down to the tubers
- Pre-measured packets with surfactant included
- Gentle on warm- and cool-season turf
- Pets and people can re-enter once dry
Patience Required
- Works slowly — yellowing starts in a day, death takes weeks
- Heavy infestations need 2–3 applications
- Two-pack covers about 2,000 sq ft total
Pick this if: Nutsedge is your one specific enemy and you want a pro-grade active ingredient without pro-grade mixing math.
Look elsewhere if: You need a general broadleaf weed killer — this one is single-minded.
5. Ortho WeedClear Lawn Weed Killer with Comfort Wand, 1.33 gal
A battery-powered wand that makes weed-spotting almost fun.
The hook here is the applicator, not the chemistry: a battery-powered Comfort Wand built into the 1.33-gallon container that accurately targets the weeds you want to kill without bending over. It kills crabgrass, dandelion, clover, chickweed, and creeping charlie down to the root, and it’s labeled for Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass, and Zoysiagrass.
No mixing is required, and owners love the ease — the wand is intuitive and the spray pattern is consistent. The trade-off is speed: this is a slow-but-sure product, with owners near Chicago reporting thistles and prickly weeds dying over weeks to a month, not hours.
There’s also a reliability caveat: a few owners mention that a particular bottle killed grass too, despite correct use, hinting at the occasional factory mixing error.
The Convenience Factor
- No mixing, no extra sprayer
- Battery wand targets weeds accurately
- Covers 6 grass types safely
- Kills weeds to the root with 1 application
The Reality Check
- Works slowly — weeks, not hours
- Hard-to-kill weeds need multiple sprays
- Rare bottles may have a mixing error
Best for: Weekly spot treatment of small weeds where you want the easiest possible applicator.
Not for: Impatient gardeners who want overnight visible results.
6. Roundup For Lawns3 Ready-To-Spray (Northern), 32 oz
Hose-end broadcast power for Northern lawns with over 250 weed coverage.
This is the broadcast play: attach the 32-ounce container to your garden hose and it becomes a Ready-to-Spray applicator covering up to 5,000 sq ft. It kills over 250 weeds, including crabgrass, dandelion, clover, and yellow nutsedge, while staying safe on Northern grasses like Kentucky bluegrass, perennial ryegrass, fescue, bermudagrass, buffalograss, and zoysiagrass.
The active ingredients blend MCPA, Quinclorac, and Sulfentrazone — a combination owners confirm wipes out dandelion and clover in a single application with grass unharmed, even in Seattle with irrigation. It starts working immediately and is rainproof in as little as 3 hours.
The honest caveats: effectiveness gets mixed feedback overall, and one owner found the hose attachment clogged with white plastic, causing dribbling instead of a spray. For hard-to-kill summer crabgrass, the manufacturer itself points you to a separate crabgrass destroyer product.
The Broadcast Edge
- Hose-end sprayer covers 5,000 sq ft
- Kills 250+ weeds including yellow nutsedge
- Rainproof in as little as 3 hours
- Safe on 6 Northern grass types
Before You Buy
- Effectiveness varies by weed and season
- Hose attachment can clog
- Summer crabgrass needs a different product
Grab it if: You have a large Northern lawn and want a hose-end broadcast application without mixing.
pass on it if: Your main enemy is mature summer crabgrass — you’ll need the PrimeSource Quinclorac instead.
7. Bonide Weed Beater Ultra, 32 oz Concentrate
The fast-acting concentrate that covers 10,000 square feet from one pint.
This is the premium concentrate for big lawns: 1 pint treats approximately 10,000 square feet, and it kills over 200 broadleaf weeds including dandelion, clover, ground ivy, bedstraw, aster, gumweed, nettle, oxalis, ragweed, and chickweed. It’s rainproof within hours once dried.
The speed is the story. Injury to weeds shows within hours of application, and plant death occurs within 7–14 days. Customers note excellent results on dollarweed and chickweed, and it’s notably effective against wild onion — one of those weeds most general products ignore.
The trade-offs: the mixing instructions are complex and require precise calculations, and some weeds like Virginia buttonweed need reapplication. A handful of owners note it can brown grass slightly if you’re careless with coverage.
The Big-Lawn Edge
- One pint covers ~10,000 sq ft
- Kills 200+ broadleaf weeds
- Visible weed injury within hours
- Rainproof after it dries
The Fine Print
- Mixing math is complex
- Stubborn weeds need multiple apps
- Careless spraying can brown grass slightly
Buy this for: A premium, fast-acting treatment across a big lawn where you’re comfortable with mixing.
Pass if: You’d rather not do concentrate math on a Saturday morning.
8. PBI/Gordon Trimec Lawn Weed Killer, One Gallon
A gallon of Trimec for the yard that’s basically a meadow.
If your property is measured in acres, not feet, this is the one. A single gallon covers 32,000 to 64,000 square feet — roughly 0.7 to 1.5 acres — and it’s formulated for cool-season grasses. It kills hard-to-control weeds including Virginia buttonweed and creeping charlie, the two weeds reviewers point out dying within one to two weeks.
One 73-year-old owner called it “the best weed killer I’ve ever used,” and the consensus is that lawns look amazing after treatment. For heavy weed pressure, owners recommend doubling or tripling the mixture — a sign that the label rate can be conservative.
The honest notes: you may receive the slightly different “Weed-Out” branded Trimec instead of the advertised product label, and the dead weeds leave yellow patches in the turf until they break down.
The Scale Play
- Covers 32,000–64,000 sq ft per gallon
- Kills Virginia buttonweed and creeping charlie
- Cool-season grass safe
- Proven across large properties
Handle With Care
- May ship as a different Trimec brand label
- Label rate often needs doubling for heavy weeds
- Dead weeds leave temporary yellow patches
Choose it if: You have a big cool-season lawn and want the lowest cost per square foot.
Reconsider if: You own a small city lot — the gallon is far more than you need.
9. PrimeSource Quinclorac 1.5L Select Liquid Crabgrass Killer, 64 oz
The quinclorac powerhouse that ends the war on crabgrass.
This is the pro-grade answer for grassy weeds. With Quinclorac at 18.92%, it’s a selective, post-emergent herbicide targeting crabgrass (large and smooth), foxtail, kikuyugrass, signalgrass, torpedograss, bindweed, clover, dandelion, dollarweed, morningglory, and speedwell — a long list that stretches well beyond crabgrass.
The results are fast and dramatic. Shoppers say crabgrass dying in 3–4 days and rotting within a week, with lawn grass completely untouched. One user summed up the season: “The crab grass is now toast!” after a late-August application showed death in 24 hours.
The key to success is pairing it with a surfactant and often dish soap for better adhesion. The caveats: a single round may kill 60–70% of crabgrass, needing a follow-up spot treatment, and Zoysia grass can turn yellow in some cases.
The Crabgrass Arsenal
- High-concentration Quinclorac 18.92%
- Kills crabgrass in 3–4 days
- Broad grassy + broadleaf weed list
- Safe on lawn grasses including fescue
Use It Right
- Needs a surfactant for best adhesion
- Heavy infestations need 2 rounds
- Zoysia may yellow in some cases
Reach for it if: Your lawn’s problem is crabgrass or foxtail and you want a measured concentrate with pro-grade strength.
it’s not for you if: Your issue is purely broadleaf weeds like clover — a standard 2,4-D blend will do.
Understanding the Specs
Active Ingredients
This is the most important line on the label. 2,4-D, Dicamba, and Mecoprop (often blended as Trimec) target broadleaf weeds. Triclopyr and Clopyralid handle tougher species like creeping charlie. Quinclorac is your crabgrass specialist, and Halosulfuron-methyl is for nutsedge. Match the ingredient to your weed for results.
Concentrate vs. Ready-to-Use
Ready-to-use (RTU) bottles are the easiest — no mixing, just spray. Concentrates cost less per application and cover far more ground, but require a sprayer and precise mixing. If you have a large lawn, concentrates like the 32-ounce and gallon options stretch your dollar; if you have a small yard, an RTU is simpler.
Coverage and Turf Safety
Coverage tells you how many square feet a bottle treats — from 2,000 sq ft for nutsedge packets up to 64,000 sq ft for a gallon. Turf safety is equally critical: every product lists the grass types it’s safe on, such as Kentucky Bluegrass, Bermudagrass, Zoysiagrass, or fescue. Always check both before spraying.
Surfactants and Rainfast Time
A surfactant is a spreader-sticker that helps the herbicide cling to weed leaves instead of beading up and rolling off. Rainfast time tells you how long before rain won’t wash the product away — as quick as 3 hours for some, or requiring a full dry for others. Both affect how well the treatment actually works.

Final Thoughts: The Verdict
