A lawn full of dandelions, clover, or creeping charlie is frustrating — you want the weeds gone without wrecking the grass you worked to grow. That is exactly what a selective broadleaf herbicide does: it targets the broadleaf intruders while leaving your turf untouched. The challenge is picking the right concentrate or ready-to-use spray from a shelf full of confusing labels. This guide cuts through the noise, stacking the eight best formulas head-to-head on speed, coverage, and what real lawns actually show after treatment.

Whether you are fighting a clover invasion or spot-treating stubborn thistle, these are the best-performing options for a weed-free lawn. The best selective broadleaf herbicide is the one that knocks out the toughest weeds fast while keeping your grass green and healthy.
Our Picks at a Glance
How To Choose The Best Selective Broadleaf Herbicide
The right herbicide depends on the weeds you have, the grass you are protecting, and how much area you need to cover. A product that annihilates dandelions might struggle against wild violet, and a concentrate that treats 16,000 square feet is overkill for a tiny urban plot. Here are the key factors to weigh before buying.
Concentrate vs. Ready-to-Use
A concentrate saves money per application and lets you dial in the dose, but you need a sprayer and a willingness to mix. A ready-to-use (RTU) bottle with a wand is grab-and-go simple — perfect for a small lawn or quick spot-treating — but you pay a premium for that convenience and get less total coverage per gallon.
Active-Ingredient Blend
The heavy hitters are 2,4-D, dicamba, triclopyr, and clopyralid. A three-way or four-way mix (like Trimec) covers a wider weed spectrum than a single active ingredient. If you are battling creeping charlie, look for triclopyr. For tough clover or thistle, a blend with clopyralid is your best bet.
Turf-Grass Safety
Not every herbicide is safe on every lawn type. Cool-season grasses like Kentucky bluegrass and fescue tolerate most formulas. Warm-season grasses like St. Augustine and centipede grass are more sensitive — some products list them as safe, others will cause burn. Always cross-check the label’s grass list with your own lawn.
Speed of Results and Rainfastness
Some formulas show wilting within hours; others take a few days. Rainfastness — the time the product needs to dry before rain washes it off — varies from a couple of hours to half a day. If you are on a tight weather window, a fast-acting, quick-drying choice gives you more flexibility.

In‑Depth Reviews
1. Fertilome Weed Free Zone Broadleaf Weed Killer Concentrate (16 oz)
Our pick — over 4.5★ from 400+ verified ratings; the strongest balance of quality and price.
The fastest-acting concentrate that shows results within hours and spares the grass.
This is the crowd favorite for a reason — it combines triclopyr and clopyralid to tackle over 80 broadleaf weeds, including clover, spurge, chickweed, and thistle. The real draw is speed: evidence of injury shows up within hours of application, and buyers report visible wilting in just two days. It is safe on a long list of turf types — Kentucky bluegrass, bermudagrass, bahiagrass, and zoysiagrass among them — so you do not have to worry about collateral damage.
The trade-off is the price per ounce. It is a concentrate, so you mix it yourself (the label recommends a straightforward rate), and a 16 oz bottle goes further than a ready-to-use jug. The thing owners praise most is effectiveness — that is the top-mentioned aspect by a wide margin. A handful note that the instructions are a bit dense, but once you measure the mix, the results speak for themselves. It covers a full area, and neighbors tend to notice the night-and-day difference within a week.
Why owners love it
- Visible results in 48 hours — weeds start yellowing fast
- Kills 80+ weed species including wild violet and sticker burrs
- Safe on cool- and warm-season grasses like Bermuda and Zoysia
- Concentrate stretches your dollar across a large lawn
The honest fit note
- Does not kill dollarweed — that needs a different homemade approach
- The label instructions feel convoluted; read carefully before mixing
Reach for it if: you want the fastest knockout of a broad weed spectrum and you are comfortable mixing concentrate.
A better match is elsewhere if: you need a grab-and-spray bottle or you are fighting only dollarweed.
2. Southern Ag Lawn Weed Killer with Trimec (32 oz)
A patented three-way blend that wiped out a dandelion invasion in two weeks without harming the lawn.
You get a patented mix of three weed killers in a 32 oz bottle — at 32 oz versus the Fertilome 16 oz, yet this one covers 5,000 square feet of turf. It works on nine different grass types, so it fits more lawns than most concentrates here. Owners mention it wipes out clover, spurge, and chickweed effectively; one reviewer notes a full dandelion invasion died in two weeks with no damage to the grass.
The honest catch is longevity. While the knockdown power is fast, many owners find the weeds return a bit quicker than they would like, requiring a follow-up spray every few weeks. It is not a season-long solution. The value-for-money feedback is positive — it is less expensive than alternatives — but plan for reapplication.
The standout stat: a 32 oz bottle treats 5,000 square feet of lawn across nine turf types.
The limiting factor: weeds can bounce back within weeks; this works best as a routine spot treatment, not a one-and-done.
Choose this when: you want a big volume of proven Trimec chemistry for a medium-to-large lawn and are okay reapplying.
skip it if: you need a single-application season-long solution.
3. Bonide Weed Beater Ultra Concentrate (16 oz)
Covers 16,000 square feet from one 16 oz bottle and targets over 200 broadleaf weeds.
Bonide claims the broadest weed hit-list on this list — over 200 species including dandelion, clover, ground ivy, ragweed, and chickweed. The concentrate mixes instantly with water in a backpack or compression sprayer, and injury to the treated weeds can appear within hours. Full plant death follows in 7 to 14 days. It is rainproof after drying, so a passing shower won’t undo your work.
The value-per-square-foot is excellent, but owners note that the mixing instructions are complex — you need to do precise calculations for your sprayer. It is highly effective on dollarweed and chickweed, but tougher perennials like Virginia buttonweed require a second application. The top praise goes to effectiveness, with the second-most feedback being that it does not damage the grass when used as directed.
What stands out
- 16,000 sq ft coverage from a single 16 oz bottle
- Over 200 listed weeds — the most versatile range here
- Rainfast within hours after drying
What to watch
- Instructions require careful mixing math
- Stubborn weeds like Virginia buttonweed need a follow-up
Best for: large lawns with a wide variety of broadleaf weeds where you are willing to calculate the mix.
Not ideal for: anyone who wants a simple pre-mixed spray or an instant one-shot solution for deep-rooted perennials.
4. Fertilome Weed Free Zone Broadleaf Weed Killer Concentrate (32 oz)
The gold-standard formula for creeping charlie — owners call it the only product that kills it overnight.
This is the larger 32 oz version of the same triclopyr-plus-clopyralid formula as our top pick. The real story here is creeping charlie. Customers note that this is the only product that truly knocks it out, with visible wilting by the next day. It also handles dandelions, spurge, and everything in between, all while leaving flowers and turf unharmed when applied carefully.
The biggest praise is effectiveness — mentioned more than 240 times — and it mixes easily in water for even spraying. The catch is the price per bottle: it is a premium concentrate. Owners also note that the label’s recommended dose can be too weak for clover; many bump it up and add a drop of dish soap for better adhesion. A small number report leakage during shipping, so check the cap on arrival.
The knockout weapon: creeping charlie wilts overnight — a claim very few products can back up.
The honest advice: you may need to dial the concentration up for clover, and the higher price per bottle makes it a targeted weapon, not a cheap blanket spray.
Reach for this if: you are fighting creeping charlie or other stubborn broadleaf weeds and want the most potent ready-to-mix formula.
Think twice if: you are on a tight budget or only need a light maintenance spray for easy dandelions.
5. PBI/Gordon Trimec Lawn Weed Killer (1 gal)
The professional-grade gallon that covers up to 64,000 square feet — ideal for serious lawn care.
This is the biggest volume in the roundup: a full gallon of Trimec concentrate that treats between 32,000 and 64,000 square feet, depending on the weed pressure. It is designed specifically for cool-season grasses, making it a favorite for fescue, bluegrass, and ryegrass lawns. Owners call it the best weed killer they have ever used, and it takes down heavy infestations of Virginia buttonweed and creeping charlie effectively.
The value-for-money feedback is mixed — it is a premium price, and some wish the bottle gave a lower cost per ounce. A common tip from experienced users is to double or even triple the recommended mixture for thick, stubborn weeds, especially when fighting an invasion from a neighbor’s yard. You get professional-grade results, but you need to be comfortable mixing at higher concentrations for the toughest jobs.
The big advantages
- Massive coverage — up to 64,000 square feet per gallon
- Kills hard-to-control weeds like Virginia buttonweed and creeping charlie
- Established Trimec chemistry trusted by pros
The trade-offs
- Premium price per bottle
- Cool-season grass only — not safe for all warm-season turf
Best suited for: owners of large cool-season lawns who want professional-grade results and are ready to mix at higher rates for tough weeds.
Less ideal for: small yards, warm-season grass, or anyone wanting an all-in-one ready-to-use spray.
6. Ortho Weed B Gon Weed Killer (24 oz RTU Trigger)
The no-mix, no-fuss trigger spray that kills over 250 listed weeds and is guaranteed not to harm the lawn.
You pull the trigger and spray — that is the convenience of Ortho Weed B Gon. It kills dandelions, clover, and 250+ other broadleaf weeds down to the root, with results visible in hours. The brand guarantees it will not harm your lawn when used as directed, which reassures first-time users. One buyer put it: “My husband loves this stuff” for clover results without killing the grass.
The caveat is that effectiveness gets mixed feedback overall. While many see great results, some owners find it does not kill every weed type thoroughly — it works best on young, actively growing weeds rather than mature, established ones. The ease of use is the top praised aspect, but if you have a large lawn, the 24 oz RTU bottle runs out fast and costs more per square foot than a concentrate.
The convenience win: zero mixing, zero measuring — just point and spray.
The honest limit: not every owner gets full kill on mature weeds; best for routine spot treatment of young growth on a small lawn.
Grab it if: you want the simplest possible weed-killing experience for a small yard or a few stubborn patches.
Look elsewhere if: you have a large area to cover or need a surefire solution for tough, established broadleaf weeds.
7. Ortho WeedClear Lawn Weed Killer (1.33 gal with Comfort Wand)
The biggest RTU jug in the lineup — 1.33 gallons with the same battery wand for max coverage.
This is the larger sibling of the 1-gallon WeedClear, giving you an extra third of a gallon for a small price bump. It uses the same fast-acting formula that kills dandelions, clover, crabgrass, chickweed, and creeping charlie down to the root. The Comfort Wand is battery-powered, so no pumping — just walk and spray. Owners appreciate that no mixing is required, and the wand makes targeted application easy. It works on six common grass types including Bermuda, fescue, and zoysia.
The honest feedback is that this product is slow-acting. Owners note wilting in days and full death in weeks, with the toughest weeds needing a month to completely melt away. The effectiveness is the most-discussed aspect, and it gets mixed reviews — it works, but not everyone is patient enough for the pace. A few owners also report the formula killed their grass when applied in high heat, so stick to the 45°F to 90°F window.
The volume advantage: 1.33 gallons means fewer trips to the store and more coverage per purchase.
The patience requirement: results take weeks, not days, and some hard-to-kill weeds need two or more applications.
Reach for this if: you want maximum RTU volume and are comfortable with a slower, steady kill over a month-long window.
A different choice fits if: you need fast, dramatic results or you spray in temperatures above 90°F.
Understanding the Specs
Active Ingredients (2,4-D, Dicamba, Triclopyr, Clopyralid)
These are the chemical compounds that do the killing. 2,4-D and dicamba are the workhorses for broadleaf control. Triclopyr is stronger on woody or vine-like weeds such as creeping charlie and wild violet. Clopyralid targets legumes like clover. Most premium concentrates combine three or four of these for broad-spectrum control — that is what “Trimec” or “three-way” means on the label.
Concentrate vs. Ready-to-Use (RTU)
Concentrate is a liquid you dilute with water in a sprayer — you get far more coverage per dollar and you control the strength. Ready-to-use comes pre-mixed in a jug, often with a wand. RTU is convenient for small yards and spot treatment, but you pay a premium for the water you are carrying. A 16 oz concentrate can treat 5,000 to 16,000 square feet, while a 1-gallon RTU covers a much smaller area.
Coverage (Square Feet)
This tells you how much lawn one bottle treats at the labeled rate. Bigger numbers (16,000 or 64,000 sq ft) fit large properties. Smaller coverage means you will need multiple bottles for a big yard. Always match the coverage to your lawn size — buying an industrial-sized jug for a postage-stamp lawn wastes money, and an RTU bottle will run out halfway through a half-acre lot.
Turf-Grass Compatibility
Every herbicide label lists the grass types it is safe on. Cool-season grasses (Kentucky bluegrass, fescue, ryegrass) tolerate most formulas. Warm-season grasses (St. Augustine, centipede, bermudagrass) are more sensitive. Never assume a product is safe — check the label. Applying an incompatible herbicide can turn your lawn brown or kill the grass outright.
