Best Broadleaf Herbicide For Dandelions for Lawns and Turf

#1 · Best Overall

1. Select Source Triad QC Select

• Form: Quart
• Weight: 1.17 kg

Best for: Late-season mixed-weed cleanup.

Why it ranks #1: Explicitly lists dandelions and residential and non-residential lawns among its uses; three active ingredients also target a range of grassy and broadleaf weeds.

Three active ingredients—2,4-D, dicamba, and quinclorac—give Triad QC Select a broad post-emergent role that includes dandelion, clover, crabgrass, and other listed weeds. Its stated late-season cleanup use can suit lawn and turf areas that missed a spring pre-emergent application.

Triad QC Select combines three named active ingredients with post-emergent use, which lets buyers consider it for visible broadleaf and grassy weeds rather than relying only on spring pre-emergent treatment. The supplied facts identify dandelion and clover alongside newly germinated one- to two-leaf crabgrass. Listed sites include residential and non-residential turf, athletic fields, roadsides, and parks. Golf turf is included with an explicit exception for tees, greens, and collars.

Skip it if you need treatment specifically for golf greens, tees, or collars; this product excludes them, while Spectracide Weed Stop is listed for lawns.

Pick Triad QC Select for post-emergent cleanup where dandelions and newly germinated crabgrass may coexist, including listed athletic-field or roadside turf. Keep its golf-turf exclusion in mind, and match application to the label and the specific site.

#2 · Fast-Acting Option

2. PBI Gordon SpeedZone EW

• Form: Liquid
• Weight: 8 oz

Best for: Rapid turf recovery schedule.

Why it ranks #2: Names dandelions among 90-plus listed weeds, reports visible effects within hours, and gives a three-hour rainfast interval and listed turf grasses.

Reseeding in as little as seven days is a useful scheduling detail for lawn owners planning turf repair after weed treatment. SpeedZone EW also lists dandelion among more than 90 weeds, visible effects within hours, and rainfastness in as little as three hours.

The stated seven-day reseeding interval helps buyers coordinate weed treatment with lawn repair, while the three-hour rainfast interval informs application timing around weather. SpeedZone EW lists dandelion and more than 90 weeds, with visible effects within hours. Its listed tolerance covers established cool- and warm-season turf species, including Kentucky bluegrass, perennial ryegrass, tall fescue, Bermudagrass, and zoysiagrass. Use remains subject to the product label and its precautions.

Skip it if you need a stated coverage area per bottle; Spectracide Weed Stop specifies up to 20,000 square feet.

Choose SpeedZone EW if you want a dandelion-listed turf treatment and are planning reseeding or working around rain. Its seven-day reseeding and three-hour rainfast intervals are key scheduling boundaries; check that your turf type is listed.

#3 · Broad Weed Coverage

3. Spectracide Weed Stop

• Form: Liquid
• Weight: 3 lb

Best for: Broad lawn weed coverage.

Why it ranks #3: Explicitly controls dandelions and more than 200 listed weeds; its 40-ounce concentrate treats up to 20,000 square feet when used as directed.

A stated coverage of up to 20,000 square feet per 40-ounce bottle gives Spectracide Weed Stop a clear scale for lawn treatment. It names dandelion, chickweed, and clover among more than 200 listed weeds, and says it kills weeds to the root while not harming lawns when used as directed.

The concentrate is diluted with water, and the stated coverage of up to 20,000 square feet helps buyers estimate how much lawn one bottle can treat. Its listed dandelion, chickweed, and clover targets address common broadleaf weeds, while the product claims root kill and overnight results. Rainfall or watering six hours after application will not wash away effectiveness. Application guidance specifies daytime temperatures between 60°F and 85°F, a practical scheduling constraint.

Skip it if you cannot apply during the stated 60°F-to-85°F daytime range; Ortho WeedClear also lists dandelion and can be applied by sprayer.

Choose this concentrate for a lawn with dandelions and other listed weeds when its coverage and six-hour rainfast timing suit your application plan. The stated temperature range matters, and lawn safety is conditional on use as directed.

#4

4. Ortho WeedClear Concentrate

• Form: Spray
• Weight: 2 lb

Best for: Sprayer-compatible lawn concentrate.

Why it ranks #4: Names dandelions and more than 200 major weeds, including broadleaf and grass weeds, and is intended for lawn use after dilution.

Compatibility with either a tank sprayer or Ortho Dial N Spray gives WeedClear two listed application routes after dilution. It names dandelions among more than 200 weeds and claims to kill listed weeds down to the root, giving lawn owners a specified target and workflow.

WeedClear’s concentrate is diluted with water according to label directions, then applied with a tank sprayer or Ortho Dial N Spray. That compatibility lets buyers use an existing tank sprayer or the named Ortho applicator rather than being limited to one listed method. The supplied description says it kills more than 200 major broadleaf and grass weeds down to the root, including dandelion, clover, and crabgrass. Avoid application when rain is expected within the label’s stated window.

Skip it if you want a ready-to-use product without mixing concentrate and water; Spectracide Weed Stop is also a concentrate, so check its label workflow.

WeedClear fits lawn owners with a tank sprayer or Ortho Dial N Spray who want a concentrate listing dandelions and other common weeds. It requires dilution and label-directed timing, including attention to expected rain.

#5 · Four-Ingredient Formula

5. Select Source Triad TZ

• Form: Liquid
• Weight: 1.16 kg

Best for: Four-way turf broadleaf control.

Why it ranks #5: Explicitly lists dandelions and combines 2,4-D, dicamba, triclopyr, and sulfentrazone for post-emergent broadleaf control in turfgrass.

Four active ingredients—2,4-D, dicamba, triclopyr, and sulfentrazone—give Triad TZ a four-way approach to post-emergent turf weeds. Its listed targets include dandelion, ground ivy, white clover, and wild violet, making it relevant for lawns with several difficult broadleaf weeds.

The four named active ingredients and two stated modes of action connect Triad TZ’s formulation to its dependable post-emergent broadleaf control claim. The supplied description says it is taken up quickly by leaves and stems and that weed growth ceases within hours, offering a stated response timeline. Its target list includes dandelion, spurge, plantains, ground ivy, and wild violet, plus suppression of yellow nutsedge. Buyers should follow label directions and avoid food-crop areas.

Skip it if you need a product with a supplied lawn coverage figure; Spectracide Weed Stop gives coverage up to 20,000 square feet per bottle.

Triad TZ suits turf owners facing dandelions alongside several tough broadleaf weeds and seeking post-emergent control. Its listed use is not for food-crop areas, and the nutsedge claim is suppression rather than control.

#6 · Multi-Site Use

6. Hi-Yield 2,4-D Selective Weed Killer

• Form: Liquid
• Weight: 4 lb

Best for: Selective 2,4-D multi-site use.

Why it ranks #6: Specifically names dandelions and lists lawns, ponds, drainage ditches, pastures, and rangelands as use sites; check label directions and rates.

A selective 2,4-D formula with listed uses spanning lawns, ponds, drainage ditches, pastures, and rangelands gives Hi-Yield a notably varied application profile. Dandelion is among its named targets, making it an option to consider when broadleaf control needs extend beyond a typical lawn.

Hi-Yield identifies 2,4-D as the basis of its selective weed control and specifically names dandelion, arrowhead, buckhorn, aster, and goatsbeard among susceptible weeds. Its listed sites range from lawns to ponds, drainage ditches, pastures, and rangelands, which can help buyers evaluate one product across different areas. The feature list also says it pairs with Hi-Yield Spreader Sticker for increased effectiveness. Application rates and instructions are on the product label.

Skip it if you need a listed use rate in the supplied details; Southern Ag Amine specifies 1 to 4 pints per acre.

Consider Hi-Yield when dandelions occur across its listed lawn, pond, ditch, pasture, or rangeland sites and a selective 2,4-D product fits your needs. Consult its label for site-specific rates and directions.

#7

7. PBI Gordon TZone SE

• Form: Liquid

Best for: Cool-weather tough-weed control.

Why it ranks #7: Designed for residential and commercial lawns and described for tough broadleaf weeds, but the supplied weed examples do not specifically name dandelions.

A combination of triclopyr and multiple active ingredients gives PBI/Gordon TZone SE a stated role in cool-weather control of tough turf weeds. Its listed targets include wild violet, ground ivy, oxalis, and clover, making it relevant to lawn owners dealing with more than one broadleaf weed.

TZone SE is described as using triclopyr with precise ratios of multiple active ingredients, supporting its stated control of tough broadleaf weeds on turf. The supplied description specifically identifies wild violet, ground ivy, oxalis, and clover, while the product is presented for residential and commercial lawns. Its gallon liquid bottle suits buyers seeking this formulation for lawn use; directions call for dilution with water according to the recommended ratio before spraying.

Skip it if you want dandelion explicitly listed or a named gallon-size concentrate; Spectracide Weed Stop lists dandelion and lawn use.

Consider TZone SE if your lawn has the named tough weeds, especially wild violet or ground ivy, and cool-weather control is a priority. Its supplied target details do not name dandelion, so buyers focused only on dandelions may prefer a product that does.

#8

8. PBI Gordon SpeedZone EW Gallon

• Form: Liquid
• Weight: 8.5 lb

Best for: Fast cool-weather turf treatment.

Why it ranks #8: A turf broadleaf formula with visible activity in hours and cool-weather performance, but the supplied listing does not explicitly name dandelions.

Visible activity within hours gives SpeedZone EW a quick feedback window after application, while the supplied description identifies it as a fast-acting cool-weather turf herbicide. Clover control is listed in as little as one week, making it relevant to lawn managers who value visible progress.

The EW, or emulsion-in-water, formulation is described as providing more complete coverage of weed surfaces than original SpeedZone, connecting formulation to application coverage. The product also reports visible activity within hours and clover control in as little as one week, useful markers for monitoring treatment. Its gallon liquid bottle is listed for turf broadleaf use. Availability is restricted in numerous states, so location is a decisive purchase consideration before selecting it.

Skip it if you live in a listed restricted state or need dandelion named in the supplied target facts; Ortho WeedClear explicitly lists dandelions.

This fits turf managers seeking quick visible activity and cool-weather performance, particularly when clover is among the weeds. Check the extensive state restriction list before choosing it, and use another option if your location is excluded.

#9

9. Southern Ag Amine 2,4-D

• Form: Liquid
• Weight: 16 oz

Best for: Pasture and fence-line coverage.

Why it ranks #9: A 2,4-D concentrate for certain grasses, lawns, and other sites that controls many broadleaf weeds, although dandelions are not named in the supplied details.

A low application rate of 1 to 4 pints per acre makes Southern Ag Amine 2,4-D a concentrate for treating broadleaf weeds across larger listed areas. Its label covers turf, pastures, rangeland, ditch banks, and fences, giving land managers several potential use sites from one liquid formulation.

The listed 1-to-4-pints-per-acre use rate connects the concentrate format to acreage-scale application, while its stated control of many broadleaf weeds and woody plants suits mixed weed problems. Listed sites include lawns, parks, golf courses, pastures, rangeland, ditch banks, and fences, so buyers can consider it across turf and non-crop areas. The product is a low-volatile amine-form 2,4-D concentrate; careful application matters because the supplied facts warn against drift and overlapping coverage.

Skip it if you need a product with a listed dandelion-specific claim and lawn coverage details; Spectracide Weed Stop lists both.

Choose it if you manage broadleaf weeds across turf, pasture, or fence and ditch areas and can follow the supplied drift and coverage cautions. Its listed uses span several sites, but do not assume every site or grass is suitable.

#10

10. Trimec 992 Broadleaf Herbicide

• Form: Liquid
• Weight: 26 lb

Best for: Large-volume broadleaf herbicide.

Why it ranks #10: The supplied information identifies a broadleaf herbicide and a 2.5-gallon format but provides no dandelion-control claim or fuller use-site details.

The 2.5-gallon package is the clearest supplied distinction for Trimec 992, a liquid identified as a broadleaf herbicide. That larger stated quantity may suit buyers evaluating volume for broadleaf treatment, but the supplied product information gives no target-weed list or application directions to guide a more specific match.

Trimec 992 is identified by name as a broadleaf herbicide and supplied as 2.5 gallons of liquid, giving buyers a defined product type and volume to consider. The manufacturer is PBI-Gordon Corporation. A relevant restriction is explicitly stated: do not apply it to Floratam St. Augustinegrass. The product may not be registered in all states, so the listed facts support checking those boundaries before use rather than assuming suitability for every lawn or location.

Skip it if you have Floratam St. Augustinegrass or need supplied dandelion-target details; Spectracide Weed Stop explicitly lists dandelion.

Trimec 992 may fit buyers seeking a 2.5-gallon liquid broadleaf herbicide, but the supplied information does not specify dandelion targets or application directions. Avoid it on Floratam St. Augustinegrass and check state registration.
