9 Best Broadleaf Weed Killer For Lawns | Turf-Safe Knockdown

The bottle to grab when the weeds are already up and you want zero setup.

Ready-to-use means what it says — no measuring, no mixing, no separate sprayer. You pick it up, spray the weeds you can see, and results show in hours. It kills dandelions, clover and other broadleaf weeds, with an advertised 250+ listed weeds on the label, and it goes down to the root. Ortho guarantees it won’t harm the lawn when used as directed. The coverage is 5,000 square feet — enough for a typical front-and-back-yard spot program, but not a full-acre treatment.

This is the pick for the person who spots a few clumps of clover on the way to the car and wants them gone without hauling equipment out of the garage. The bottle weighs 1.5 pounds; a 24-ounce unit. It is light, dead simple and forgiving — the sort of thing a first-timer can use without worrying about burning the lawn.

How does it compare to the PBI Gordon jug above? Different tools. The jug is for people treating a whole lawn with a sprayer; this trigger is for spot control. The feedback from buyers here is a familiar refrain — a wife up on one such thread reports her husband “loves” this stuff and sees great results killing clover and other weeds without harming the grass. That is the outcome most buyers get: weeds gone, lawn intact. The trade-off is the obvious one — for a big lawn you will go through bottles fast, and a trigger format gives you no way to mix stronger for tough customers like thistle or henbit. Then again, it is not trying to be a sprayer product. If you want a no-fuss bottle that solves the visible weeds without a plan or a tank, this is the one.

One quart stretched to cover an acre of lawn, ditchbank or fencerow.

This is the bottle the guy at the farm co-op recognizes. It is a concentrated 2,4-D amine herbicide in a one-quart container — 32 fluid ounces — and the label coverage is a full 43,560 square feet, or one acre. That is double the coverage of the 16-ounce Fertilome Weed Free Zone bottle per fluid ounce. It mixes with other products, so if you are building a custom tank blend for a specific weed problem, this is a flexible base to start from.

The use list goes well past your lawn. It is labeled for broadleaf weed control in lawns, pastures, rangeland, corn, sorghum, wheat and barley, plus fencerows, drainage ditchbanks, rights-of-way and industrial sites. If you have more than just grass to treat — a fence line, a ditch, a patch of pasture — this single bottle handles all of it.

What buyers here consistently note is that it kills the weeds, not the grass, and it does so economically. One 5-star review sums the experience up cleanly: a buyer applied it directly on Canada Thistle leaves in a new lawn and reports it “literally took one treatment” to send the thistle packing. Another buyer mentions it takes care of woody types like fern and sagebrush — plants that shrug off other products — though those may need a few weeks. The honest catch is handling. This is a serious chemical concentrate and needs careful storage and proper use of gloves and eye protection; one reviewer noted their quart arrived with only the foil top and no cap, so inspect the seal on arrival. It also has some 2,4-D drift sensitivity to sensitive broadleaf plants nearby (be careful on windy days). For the price of one quart that covers a whole acre, it is hard to argue with a bottle this economical.

The trio of actives that handles creeping charlie when everything else taps out.

If your creeping charlie laughs at the standard bottle, this is the one to try. It is a liquid concentrate built around a triclopyr + clopyralid formula plus a third active, and it controls over 80 broadleaf weeds including clover, spurge, chickweed and thistle. The 16-ounce bottle shows evidence of injury within hours of application. It is labeled as safe on Kentucky Bluegrass, Bermudagrass, Bahiagrass and Zoysiagrass — check the full list on the label for your turf. For best results, spray when the weeds are young and actively growing, in spring, summer or fall.

The secret is the actives. Triclopyr targets tougher woody and cool-season broadleaf weeds like creeping charlie; clopyralid handles clover and thistle; the blend means you do not need a second product for a stubborn weed. Coverage is labeled simply as “Full” — the label defines the exact mix rate. A buyer who ran a control test reported night-and-day results in 1 week, and neighbors noticed the difference. That is a strong outcome.

What wins people over is the creeping charlie performance — the weed most other bottles cannot touch — and the fact that it will not bleach your lawn the way some of the harsher glyphosate-adjacent products can. The honest trade-offs: the mix instructions are verbose and take real reading; it is not the cheapest bottle in this compare group (a “pricey, convoluted instructions” note appears in buyer feedback); and it does not handle dollar weed, so that one needs a separate spot treatment. The bottle also cannot be applied while seeding. If creeping charlie, wild violet and clover are your problem weeds, the triclopyr + clopyralid actives here are worth the extra label-reading.

A full gallon worth of mix that treats up to 32,000 square feet of lawn.

Large-plot lawns need coverage more than they need a fancy label. This gallon jug of concentrate treats up to 32,000 square feet of Northern Grasses or 42,500 square feet of Southern grasses, which covers a serious half-acre-plus lawn. It kills more than 200 types of weeds as listed and goes down to the root. Rainproof in hours — rainfall or watering 6 hours after application will not wash away effectiveness. Results are advertised in hours.

The selling points are straightforward: massive coverage, ease of mixing, and rainfast timing that lets you spray without obsessing over the forecast. The concentrate is easy to mix and spread with a sprayer, which is the sort of thing that matters when you are working a very large area and cannot afford finicky mixing.

The honest part is effectiveness. It is a “mixed” aspect in buyer feedback across the product’s review base — some buyers get excellent results on the weeds named on the label and others find it fails on tough, deep-rooted holdouts like bullhead sticker weeds and fox tail. The recurring complaint is speed: a few buyers report you do not see results in hours the way the bottle suggests, especially on hard customers. On easier weeds — dollar weed, chickweed, nutsedge — it does work, and buyers here note success on clover, dandelion and spurge. For big lawns with a manageable weed set, the value per square foot is the whole pitch, and it delivers — one buyer calling it “excellent” for getting more coverage than the big-box store. If your lawn’s weeds are the standard broadleaf set, the coverage-to-price ratio makes this jug very tough to top.

The one you reorder every spring — 16 ounces that treat a sixteenth of an acre.

Versatility is the whole pitch here. Kills over 200 broadleaf weeds in one easy step — dandelion, clover, ground ivy, bedstraw, aster, gumweed, nettle, oxalis, ragweed, chickweed and many more. The bottle is designed to kill broadleaf weeds in lawns, roots and all, without harming lawn grasses when used as directed. Coverage is 16,000 square feet from just 16 ounces. Injury can be noticed within hours of application and plant death can occur within 7-14 days. Rainproof within hours. Easy mix with water and apply with a backpack, compression or knapsack sprayer — the concentrate instantly mixes in.

As one buyer writes it up: “BEST WEED KILLER EVER” — that is a person who had been hunting for the right product for four years and found this one killed the weeds in a single application. That urgency is telling, and it lines up with the pattern in the customer feedback: owners consistently describe their lawns looking great after treatment and the product working without damaging the grass.

The catch is a dose-size one. Weeds that are supposed to be suppressed sometimes do not go away — wild violet, for example, holds up for some users, and severe infestations may need retreatment. The value for money and the weed-damage outcomes both sit as mixed aspects in the feedback, so count on this bottle to solve most of your weed problem but not come back for everything on the first try. The mix instructions also take careful reading — precise dosage calc is not optional if you want the results and not just the label. For anyone comfortable mixing a concentrate and applying it with a pump sprayer, this is a workhorse for a season of spot treatments.

Seven days from spray to seed — the turnaround no other bottle here can match.

Reseed in as little as 7 days — that single figure changes how you plan a lawn rescue. If you are killing weeds now so you can overseed this month, this 20-ounce liquid concentrate is the fastest turnaround on this list. It controls 90+ listed weeds including white clover, dandelion, ground ivy, spurge, goosegrass and nimblewill, and it is a fast-acting cool-weather performer with visible effects within hours. Rainfast in as little as 3 hours. Labeled for use on Kentucky bluegrass, perennial ryegrass, tall fescue, Bermudagrass and zoysiagrass and others as listed.

The active blend is a four-way herbicide: 2,4-D, 2-ethylhexyl ester, Dicamba DMA salt, Carfentrazone-ethyl and Mecoprop-p DMA salt. That mix is the reason it works across the cool-weather weeds as well as the summer ones. The label walks you through mix rates for warm-season and cool-season grasses separately so you can dial it in for what you actually have.

Followers of this bottle are done hunting. As one owner put it: “Been trying to rid myself of these weeds for years!” after three applications cleaned it up. That sense of relief matches the pattern across buyer feedback — the standout is effectiveness, and the users who get the mix dialed in describe results inside 24 hours. The recurring piece of advice is dosage discipline: do not over-spray, and do not spray the same weeds twice; over-application can burn grass. That is the honest catch — the performance is there if you measure. Buy a cheap graduated mixing cup and it is not a problem. If you are killing weeds in order to reseed, no other bottle in this compare group gives you the same 7-day window back.

A full gallon of 3-way blend that stretches to 64,000 square feet in the South.

One gallon covers 32,000 to 64,000 square feet — northern to southern lawns — so this single bottle handles most residential lawn jobs with plenty to spare. It kills 230+ listed broadleaf weeds without harming most lawn grasses when used as directed, and it is a 3-way herbicide blend in concentrated form. The 3-way actives are why it plays nicely with most turfgrass types; check the label for your exact grass.

North lawns get 32,000 square feet of treatment; southern lawns stretch to 64,000. Either way, this is the coverage-to-price pick on the list — one jug for a season, or two if you are spot-treating. It is a serious bottle for a serious yard, and the label rate is fixed so you know exactly what you are mixing.

The buyer track record here is practical: it kills the weeds in your grass area, and it works, but it is not a miracle product for every last weed. One reviewer notes this bluntly — not every lawn weed is affected — and the honest expectation is that stubborn customers like wild violet may need more than one pass. Where it shines is the everyday broadleaf set: clover, dandelion, plantain. Buyers who have sprayed it in the spring report clearer lawns and fewer dandelion comebacks. If your lawn is a standard mix of common broadleaf weeds and you want one bottle that covers a big area, this is the smart utility pick of the group.

The 2.5-gallon jug you buy once, spray for a year, and pass down to a neighbor.

The label lists three dimethylamine-salt actives — the salts of 2,4-D, mecoprop-p and dicamba — which is the classic broadleaf chemical family adapted for serious volume use. It is labelled for residential, institutional and commercial lawns, sports turf, parks and recreation areas, condominiums and townhouse grounds. It also covers golf course fairways and sod farms.

What it controls: dandelion, clover, knotweed, henbit, chickweed, plantain, spurge and many others, for a cost-effective choice on a wide range of broadleaf weeds. One buyer mentioned running 6 pints to an acre as a mix — enough to knock back clover and other weeds across a serious plot. Another buyer worked through invasive Japanese Knotweed with months of intermittent application, succeeding where other approaches did not. That is a job most residential bottles simply cannot handle by themselves.

The honest pitch: this is a serious herbicide sold in a size that assumes you already know what you are doing with it. It is labeled as a cost-effective choice, but “cost-effective” at this scale still means a real investment compared to smaller bottles; some customers find the price high even so. Its coverage spec is listed as about 975 square feet at the label rate, which means you mix as needed rather than douse the whole yard. If you manage multiple properties, treat larger acreage, or just want to buy in bulk so a full season of weeds never catches you short, this is the endgame bottle of the group.
