Best Broadleaf Herbicide For Lawns: 10 Options Compared

#1 · Best Overall

1. Ortho WeedClear

• Weight: 9.4 lb
• Form: Spray

Best for: Precise Lawn Spot Application.

Why it ranks #1: Ready-to-spray one-gallon format with Comfort Wand; the listing says it targets over 250 common broadleaf weeds and protects grass when used as directed.

The continuous-spray Comfort Wand provides precise control without pumping, making Ortho WeedClear convenient for directing treatment at lawn weeds. Its lawn-friendly formula contains three proven ingredients and is stated to avoid harming grass when used as directed, while the listing names more than 250 common broadleaf weeds.

The Comfort Wand’s continuous spray and no-pumping operation can simplify lawn application, while its precise spray control supports targeted placement. Ortho says the formula kills more than 250 common broadleaf weeds, including dandelions, clover, poison ivy, chickweed, and dollarweed, without harming grass when used as directed. The supplied instructions say not to apply when rain is expected within one hour and to let the spray dry before people or pets enter the treated area.

Skip it if you cannot keep people and pets out of the treated area until the spray dries, as the supplied directions require.

This ready-to-apply gallon suits lawn owners who value a wand for controlled spraying and want coverage of listed weeds such as dandelions and clover. Follow its timing and drying directions before people or pets return.

#2 · Best Cool-Weather Option

2. SpeedZone EW Lawn Weed Killer

• Weight: 8 oz
• Form: Liquid

Best for: Reseeding and Cool-Weather Lawns.

Why it ranks #2: Labeled for several cool- and warm-season turfgrasses, controls 90+ listed weeds, and lists visible effects within hours and rainfastness in three hours.

A reseeding interval as short as seven days sets this SpeedZone EW listing apart for lawn owners planning to repair treated areas. It also reports visible effects within hours, rainfastness in as little as three hours, and use on several named cool- and warm-season turfgrasses.

SpeedZone EW controls more than 90 listed weeds, including white clover, dandelion, ground ivy, and spurge, giving buyers a broad stated target list. Its visible effects within hours and rainfastness in as little as three hours help inform expectations after application. The seven-day reseeding interval is useful for planning lawn repair, while the listing names Kentucky bluegrass, perennial ryegrass, tall fescue, Bermudagrass, and zoysiagrass among labeled grasses. Follow the full label and precautions.

Skip it if you need a product with no waiting period before reseeding; this listing specifies as little as seven days, not immediate reseeding.

This liquid is a fit for lawn owners targeting listed weeds while planning reseeding or working around rainfall. Its seven-day reseeding interval and three-hour rainfast claim are minimum stated timings; consult the full label for your turf and application.

#3 · Best Tough-Weed Blend

3. T-Zone Turf Herbicide

• Weight: 2.4 lb
• Form: Liquid

Best for: Cool-Weather Tough-Weed Control.

Why it ranks #3: Four listed active ingredients include triclopyr and sulfentrazone; the product also lists yellow nutsedge suppression and cool-weather use as low as 50°F.

Four active ingredients—triclopyr, 2,4-D, dicamba, and sulfentrazone—give T-Zone a broad chemical mix for difficult lawn weeds. Its stated cool-weather use down to 50°F can help lawn-care operators address weeds when temperatures limit other treatment windows, while yellow nutsedge suppression adds a specific target beyond broadleaf control.

T-Zone is listed for residential, commercial, and golf sites, so its stated use spans home lawns and managed turf. The four-ingredient formulation pairs with fast visual response, which the product identifies as a way to reduce callbacks or complaints; that may matter to professionals managing visible properties. Its cool-weather option, specified as low as 50°F, offers a defined temperature range for treatment planning. It is a liquid concentrate, so application follows its label directions.

Skip it if you need a stated mixing rate or coverage figure before choosing a concentrate; those details are not included in the supplied listing.

For homeowners and turf professionals seeking a multi-ingredient liquid for tough weeds, including yellow nutsedge, T-Zone offers a cool-weather treatment option. Its stated temperature floor is 50°F; follow the product label for application directions.

#4 · Best Southern-Grass Fit

4. Trimec Southern

• Weight: 2.1 lb
• Form: Liquid

Best for: Sensitive Warm-Season Turf.

Why it ranks #4: Specifically formulated for sensitive warm-season turfgrasses and lists control of more than 90 broadleaf weeds, including dandelion.

A high degree of tolerance in sensitive warm-season turfgrasses is the defining feature of TRIMEC Southern. That makes this liquid broadleaf herbicide a relevant choice for lawn owners who want weed control while accounting for vulnerable southern grasses, with the listing also highlighting clover and chickweed control.

The product combines a wide spectrum of broadleaf weed control with stated tolerance for sensitive warm-season turfgrasses, connecting weed treatment to the needs of southern lawns. Its listing calls the Trimec amine complex best for clover and chickweed, while also describing it as an economical clover-control option for North or South. The supplied use rate is 0.37–1.1 fluid ounces per 1,000 square feet, giving buyers a labeled range to consult when planning application.

Skip it if you want a ready-to-spray applicator rather than a liquid product with a listed per-area use rate.

Choose this liquid if your lawn has sensitive warm-season grass and clover or chickweed is a concern. Its listed application rate spans 0.37–1.1 fluid ounces per 1,000 square feet, so use the label to guide rate selection.

#5

5. Nufarm Triplet SF

• Weight: 2 lb
• Form: Liquid

Best for: Adjustable-Rate Turf Treatment.

Why it ranks #5: A selective post-emergent option for cool- or warm-season turf, with three herbicides and flexible application rates for maintenance or problem areas.

Flexible application rates are the defining feature of Nufarm Triplet SF, allowing higher rates for problem areas and lower rates for turf maintenance. Its three selective herbicides and suitability for cool- or warm-season turf make it relevant to buyers adapting treatment intensity to lawn conditions.

Triplet SF is a post-emergent broadleaf herbicide that combines three selective herbicides, according to the listing. The flexible rate approach connects higher application rates with problem areas and lower rates with turf maintenance, giving buyers a stated way to vary treatment by need. Its fit extends to both cool- and warm-season turf, and sod farms are also named as an intended use. The supplied information does not give the actual rate figures, so consult its label before application.

Skip it if you need exact application rates in the supplied listing; Liquid Harvest Lawn Weed Killer provides a stated per-gallon mixing range.

Choose Triplet SF if you want a selective post-emergent option for cool- or warm-season turf and value rate flexibility for maintenance versus problem areas. Its listing does not give the actual rates, so verify them on the label first.

#6

6. Triad Select

• Weight: 12.11 kg
• Form: Liquid

Best for: Cool- and Warm-Season Turf.

Why it ranks #6: A selective post-emergent concentrate for cool- and warm-season grasses, listing dandelion, clover, and plantain among target weeds.

Use on both cool- and warm-season grasses is the central advantage of Triad Select for buyers managing varied turf types. Its three-way active-ingredient combination targets dandelion, clover, plantain, and other listed broadleaf weeds, giving the 2.5-gallon liquid a broad lawn-use profile.

Triad Select contains 2,4-D, MCPA, and dicamba, with listed concentrations of 30.89%, 8.23%, and 3.77%, respectively. That three-way combination is paired with post-emergent selective control, so the product is intended for weeds already present in compatible turf. The listing names dandelion, clover, and plantain and gives examples of cool-season grasses such as Kentucky bluegrass, tall fescue, and ryegrass. Its use on warm-season grasses is also stated; consult the full label for specifics.

Skip it if you need a stated mixing rate or per-area application direction in the supplied product information before choosing a concentrate.

Triad Select suits buyers treating compatible cool- or warm-season lawns for post-emergent broadleaf weeds. Its 2.5-gallon liquid format and three-way ingredients may fit larger treatment needs, but the supplied details do not state a mixing rate.

#7

7. Liquid Harvest Lawn Weed Killer

• Weight: 9 lb
• Form: Liquid

Best for: Low-Odor Three-Way Concentrate.

Why it ranks #7: A lawn-targeted three-way concentrate lists 2,4-D, MCPA, and dicamba, with a mix rate of 0.67–1.5 fluid ounces per gallon.

A low-odor formulation distinguishes Liquid Harvest Lawn Weed Killer for buyers who want to minimize unpleasant smells during application. Its three-way 2,4-D, MCPA, and dicamba blend is listed for controlling dandelions, clover, and other broadleaf weeds while leaving lawn grass unharmed when used as directed.

The concentrate combines 30.89% 2,4-D, 8.23% MCPA, and 2.77% dicamba, giving it the three-way control described in the listing. Its mixing direction—0.67 to 1.5 fluid ounces per gallon of water to cover 1,000 square feet—helps buyers plan a diluted application. The low-odor formulation addresses smell during use, while directions require keeping children and pets away from treated areas until the product has dried.

Skip it if you cannot keep children and pets away from treated areas until dry; Ortho WeedClear with Comfort Wand has the same listed drying precaution.

This concentrate suits lawn owners seeking three-way broadleaf control with a stated mixing range and lower-odor formulation. It is not a fit when treated areas cannot remain off-limits to children and pets until dry; follow all directions.

#8

8. SpeedZone EW Broadleaf Herbicide

• Weight: 8.5 lb
• Form: Liquid

Best for: Fast Cool-Weather Weed Response.

Why it ranks #8: The gallon listing claims rapid cool-weather control and clover control in as little as one week, but it lists sales restrictions in multiple states.

Visible weed activity within hours gives SpeedZone EW a clear appeal when a quick visual response matters. The listing also reports clover control in as little as one week and calls it a fast-acting cool-weather product, making this gallon liquid a fit for buyers who prioritize speed and have eligible turf and location.

SpeedZone EW’s emulsion-in-water formulation is described as delivering more complete coverage of the weed surface than original SpeedZone, connecting formulation to the product’s rapid-control goal. The listing says visible activity can appear within hours and clover control can occur in as little as one week. Its cool-weather performance adds a treatment window beyond warm conditions. However, the supplied restrictions exclude numerous states, so buyers need to check the listed locations before choosing this gallon concentrate.

Skip it if you live in a state on the product’s restriction list; Ortho WeedClear with Comfort Wand is a listed alternative for lawn application.

This gallon liquid suits lawn-care buyers seeking rapid visible activity and cool-weather control, especially when clover is a target. It is not a fit for buyers in the states named in its restrictions; check those limits before selecting it.

#9

9. Trimec 992

• Weight: 26 lb
• Form: Liquid

Best for: Large-Quantity Trimec Option.

Why it ranks #9: A 2.5-gallon broadleaf concentrate, but its safety information says not to apply it to Floratam St. Augustinegrass and notes state registration may vary.

The 2.5-gallon container is the clearest differentiator of Trimec 992, giving buyers a larger quantity of liquid broadleaf herbicide in one package. Its listing identifies the product as a broadleaf herbicide but supplies few further performance details, so its fit depends on label compatibility and the need for that quantity.

Trimec 992 is supplied as a 2.5-gallon liquid, a format that may suit buyers planning for a larger quantity on hand rather than a small container. The product information does not provide specific weed targets, application rates, or turf compatibility beyond a warning not to apply it to Floratam St. Augustinegrass. That warning is important when assessing fit, and the supplied safety information also calls for keeping it away from children and avoiding skin and eye contact.

Skip it if you need listed weed targets, application rates, or confirmation of compatibility with your turf before selecting a herbicide.

Trimec 992 may suit buyers seeking a 2.5-gallon liquid broadleaf herbicide and who can consult its full label for use details. Do not apply it to Floratam St. Augustinegrass, as the supplied safety information explicitly warns against that use.

#10

10. Southern Ag Amine 2,4-D

• Weight: 16 oz
• Form: Liquid

Best for: Turf and Non-Crop Sites.

Why it ranks #10: The listing covers certain grasses in lawns, parks, and golf courses, but gives less lawn-specific weed and turf guidance than the higher-ranked choices.

A listed use range spanning lawns, parks, golf courses, pastures, and several non-crop areas distinguishes Southern Ag Amine 2,4-D. This liquid concentrate targets many broadleaf weeds and woody plants, so it can suit buyers whose treatment needs extend beyond a conventional lawn.

The product contains 2,4-D in a low-volatile amine form, specified as 3.8 pounds per gallon acid equivalent, and its listed uses include certain grasses in lawns, parks, golf courses, and pastures. It also names fences, ditch banks, non-crop sites, small grains, and corn. A low use rate of 1 to 4 pints per acre is presented, but the directions caution against spray overlap and drift to susceptible plants, making careful application relevant.

Skip it if you cannot apply carefully enough to avoid overlap and drift to susceptible plants; Ortho WeedClear with Comfort Wand offers precise spray control for lawns.

Consider this concentrate if you need a listed 2,4-D option for lawn turf as well as sites such as pastures or ditch banks. Its broad range of uses comes with a clear need to prevent overlap and spray drift.
