Best Weed Killers For Lawns for Broadleaf Weeds and More

#1 · Best Overall

1. Gordon SpeedZone Lawn Weed Killer

• Weight: 16 oz
• Form: Spray

Best for: Large lawns needing fast results.

Why it ranks #1: Controls 75+ lawn weeds, including clover and ground ivy, with visible results in 24 hours and coverage listed at 14,000 to 18,000 square feet.

Visible weed changes within 24 hours give Gordon’s SpeedZone a quick-response role for lawn owners who want to see treatment progress without waiting days. Its concentrate controls more than 75 listed lawn weeds, including clover, creeping Charlie, and dandelions, while the label says it does not harm lawn grasses when used as directed.

Coverage of about 14,000 to 18,000 square feet makes this 20-ounce concentrate relevant to larger properties, while the specified mix rate of 1.4 fluid ounces per 1,000 square feet gives buyers a starting point for calculating application needs. The product is a spray concentrate, so it must be mixed with water before application. Reseeding is listed as possible after two weeks, and cool-weather performance is a stated feature; shipment is restricted in several states.

Skip it if you need a ready-to-use applicator; Ortho WeedClear with Comfort Wand provides continuous spray without pumping.

For owners treating a broad lawn weed mix who value quick visible progress, SpeedZone offers substantial stated coverage and a two-week reseeding interval. Check the shipment restrictions and plan to mix the concentrate before use.

#2 · Longest Residual

2. BioAdvanced Season Long Weed Killer

• Weight: 2.1 lb
• Form: Liquid

Best for: Established lawns needing residual prevention.

Why it ranks #2: Targets 170+ listed broadleaf and grassy weeds on established lawns, with dithiopyr providing up to four months of prevention for listed dandelion and clover.

Up to four months of listed dandelion and clover prevention gives BioAdvanced Season Long Lawn Weed Killer a role beyond treating visible weeds. Its three-herbicide formula combines dicamba, penoxsulam, and dithiopyr to control more than 170 listed broadleaf and grassy weeds on established lawns.

The formula pairs two post-emergent active ingredients with pre-emergent dithiopyr, allowing it to address existing weeds while also preventing listed weed seeds from germinating. The stated residual prevention lasts up to four months for dandelion and clover, and the weed list includes crabgrass, nutsedge, and chickweed. That combination suits buyers seeking both current control and longer prevention on established lawns. It is a 32-ounce liquid concentrate, so users need to follow label directions for mixing and application.

Skip it if you want a granular treatment rather than liquid concentrate; Scotts Weed Control for Lawns uses a granular format for broadleaf weed control.

BioAdvanced suits owners of established lawns looking to address existing weeds and extend prevention of listed dandelion and clover. Its concentrate requires label-directed application, and the supplied lawn-use claim is for established turf.

#3 · Easiest Application

3. Ortho WeedClear with Comfort Wand

• Weight: 9.4 lb
• Form: Spray

Best for: Precise spraying without pumping.

Why it ranks #3: The included continuous-spray Comfort Wand needs no pumping and offers precise control; the formula targets more than 250 listed broadleaf weeds.

Ortho’s continuous-spray Comfort Wand provides precise control without pumping, making application easier to direct across listed lawn weeds. Its formula targets more than 250 common broadleaf weeds, including dandelions, clover, poison ivy, chickweed, and dollarweed, while the lawn-friendly claim depends on use as directed.

The one-gallon spray format pairs with the Comfort Wand, so users can apply a directed stream without mixing concentrate or pumping the applicator. That setup suits targeted lawn treatment where control over spray placement matters. The product lists more than 250 common broadleaf weeds and says it will not harm grass when used as directed. Application timing also matters: do not apply when rain is expected within one hour, and allow the spray to dry before people or pets enter treated areas.

Skip it if you need a concentrate for tank-sprayer coverage across very large plots; Spectracide Large Plot Weed Stop For Lawns Concentrate lists up to 42,500 square feet.

This is a good fit for lawn owners who prefer controlled, ready-to-use spraying over mixing a concentrate. Consider the one-hour rain restriction and keep people and pets off treated areas until the spray dries.

#4 · Broad Coverage

4. Spectracide Weed Stop Concentrate

• Weight: 3 lb
• Form: Liquid

Best for: Mid-size lawns using a tank sprayer.

Why it ranks #4: The 40-ounce concentrate treats up to 20,000 square feet and controls more than 200 listed weeds, with overnight results and rain resistance after six hours.

A 40-ounce bottle covers up to 20,000 square feet, giving Spectracide Weed Stop for Lawns Concentrate a defined role for medium-to-large lawns. It controls more than 200 listed weeds, including dandelion, chickweed, and clover, and is described as killing to the root with overnight results.

This liquid concentrate needs to be mixed with water, so application involves more preparation than using a ready-to-spray product. In return, its stated coverage reaches 20,000 square feet, and rainfall or watering six hours after application will not wash away effectiveness. Apply when daytime temperatures are between 60 and 85°F. The lawn-friendly claim is conditional on following directions, so buyers should also check the product label’s complete weed list and use instructions.

Skip it if you need coverage beyond 20,000 square feet in one bottle; Spectracide Large Plot Weed Stop For Lawns Concentrate treats larger listed areas.

This concentrate suits lawn owners who can mix and apply a liquid treatment and want listed coverage up to 20,000 square feet. Its temperature window and six-hour rainproof interval matter when planning application.

#5 · Largest Coverage

5. Spectracide Large Plot Weed Stop

• Weight: 9 lb
• Form: Liquid

Best for: Very large lawns with sprayer access.

Why it ranks #5: One gallon treats up to 32,000 square feet of Northern Grasses or 42,500 square feet of Southern Grasses, suiting large lawns when temperatures are appropriate.

Treating up to 42,500 square feet of Southern grasses from one gallon makes Spectracide Large Plot Weed Stop a practical concentrate for expansive lawns. Its formula kills more than 200 listed weed types, including dandelion, chickweed, and clover, while rainfall or watering six hours after application will not wash away its effectiveness.

The listed coverage varies by grass type: up to 32,000 square feet for Northern grasses or 42,500 for Southern grasses. Because this is a concentrate, buyers mix it with water and apply it using a tank sprayer, making it a better fit for people equipped for that workflow than for spot treatment with a ready-to-use wand. Apply between 60 and 85°F; the product information warns that hotter conditions can damage grass.

Skip it if you want a smaller concentrate for a lawn up to 20,000 square feet; Spectracide Weed Stop for Lawns Concentrate 40 Oz covers that area.

Choose this gallon concentrate for extensive lawns when you have a tank sprayer and can apply within its stated temperature range. Its large-area coverage is useful, but the Northern and Southern grass figures differ.

#6

6. Gordon Trimec Lawn Weed Killer

• Form: Liquid

Best for: Cool-season grass weed control.

Why it ranks #6: Controls 230+ listed broadleaf weeds and covers 32,000 to 64,000 square feet per gallon; the product is specifically described for cool-season grasses.

Compatibility with cool-season grasses is the defining reason to consider PBI/Gordon Trimec Lawn Weed Killer. The one-gallon liquid is listed for Kentucky bluegrass, perennial rye, and fescues, among other grasses, and controls more than 230 listed broadleaf weeds, including hard-to-control lawn weeds.

A stated coverage range of 32,000 to 64,000 square feet from one gallon can help owners estimate how much area a container may treat, though actual coverage depends on the application rate. Its broad-spectrum control targets listed broadleaf weeds, while the product information says it does not harm most lawn grasses when used as directed. The liquid format requires an application plan suited to the label directions; the supplied details do not identify a dedicated wand or other applicator.

Skip it if you want a ready-to-use wand and precise continuous spraying; Ortho WeedClear with Comfort Wand applies without pumping.

Trimec fits owners of listed cool-season lawns facing a wide range of broadleaf weeds, especially when treating a large area. Check grass compatibility and label directions before applying, since the coverage range depends on rate.

#7

7. Scotts Weed Control for Lawns

• Weight: 14.1 lb
• Form: Granule

Best for: Granular treatment for broadleaf weeds.

Why it ranks #7: This granular formula controls over 200 listed weeds, but its label excludes several turf types, including Dichondra and Floratam St. Augustinegrass.

Scotts Weed Control for Lawns uses a granular formula that starts working on contact and kills listed broadleaf weeds down to the root. It controls more than 200 weed types, including dandelion, clover, chickweed, and ground ivy, offering an alternative to liquid lawn sprays for compatible turf.

The granule format changes the application workflow from mixing and spraying a liquid to distributing a dry treatment across the lawn. Its stated weed control covers more than 200 listed types, and the instructions say not to wash product from weed leaves for one to two days, followed by thorough watering. Turf compatibility is a key boundary: do not use it on Dichondra, carpetgrass, Floratam St. Augustinegrass, creeping bentgrass, or turf where desirable clovers are present.

Skip it if you have Floratam St. Augustinegrass or want a liquid spray; PBI/Gordon Trimec is listed for Bermuda grass and cool-season grasses.

Scotts suits owners of compatible residential lawns who want granular control of a broad list of weeds. Confirm the turf is not among the excluded grasses and follow the wait-before-watering directions for weed leaves.

#8

8. BASF Drive XLR8 Crabgrass Killer

• Weight: 4.2 lb
• Form: Liquid

Best for: Crabgrass control with residual action.

Why it ranks #8: A specialized fit for crabgrass and other listed weeds, with rainfastness in less than an hour and up to 30 days of residual control.

Up to 30 days of residual control makes BASF Drive XLR8 a notable option for buyers addressing crabgrass and other listed weeds in lawn and turf settings. Its water-based formulation supports faster plant uptake, while the product is rainfast in less than an hour after application.

This 64-ounce liquid concentrate combines a water-based formulation, described as enabling faster uptake, with up to 30 days of residual control that may reduce the need for frequent applications. Rainfastness in less than an hour gives the treatment a relatively short stated interval before rainfall can affect planning. It is a concentrate, so buyers must follow the label for mixing and application. The supplied information identifies post-emergent grassy and broadleaf weed control, including crabgrass, but does not state a treatment coverage area.

Skip it if you need a stated large-area coverage figure before choosing a concentrate; Spectracide Large Plot Weed Stop For Lawns Concentrate lists coverage by grass type.

Drive XLR8 suits lawn and turf buyers focused on crabgrass control who value residual action and a short rainfast interval. Since no coverage figure is supplied, consult its label to plan mixing and application for your area.

#9

9. Southern Ag Amine 2,4-D

• Weight: 16 oz
• Form: Liquid

Best for: Broadleaf weeds beyond the lawn.

Why it ranks #9: The concentrate is labeled for certain grasses in lawns and other sites, but its low use rate and broad application contexts make it less lawn-specific.

Use across certain lawns, parks, golf courses, and pastures gives Southern Ag Amine 2,4-D a broader range of listed settings than a lawn-only treatment. Its liquid concentrate controls many broadleaf weeds and woody plants, with a low use rate of one to four pints per acre.

The acre-based application rate makes this concentrate most relevant to buyers accustomed to measuring and applying treatments over larger or varied areas, rather than seeking a ready-to-use spot spray. Listed sites include certain grasses in lawns, parks, golf courses, and pastures, as well as rangeland, ditch banks, and fences. The product also controls woody plants. Directions caution users to apply accurately without overlap and avoid drift to susceptible plants, making careful coverage and placement central to its use.

Skip it if you want a ready-to-use lawn wand and do not need acre-based mixing; Ortho WeedClear with Comfort Wand sprays without pumping.

Southern Ag fits experienced users treating listed lawn grasses or broader sites such as pastures and ditch banks. Its acre-based rate and drift caution make accurate measurement and careful application important.

#10

10. Spruce Weed & Grass Killer

• Weight: 5.4 lb
• Form: Multiple

Best for: Spot treatment for mixed weeds.

Why it ranks #10: This non-selective product kills grassy and broadleaf weeds, so it can also damage lawn grass; it is a poor match for treating weeds within turf.

Visible results in one hour give Spruce Weed & Grass Killer3 a quick-response option for spot treatment, including grassy weeds and broadleaf weeds. The ready-to-use, non-selective formula can treat up to 400 weeds per bottle, but it is not a selective lawn treatment and can kill wanted grass.

A power wand and included AA batteries provide an applicator setup without requiring a separate mixing step, while the 64-ounce bottle is listed to treat up to 400 weeds. Its non-selective action targets broadleaf and grassy weeds, with visible changes in one hour and dead weeds in one day. Because it is a weed and grass killer, direct spraying carefully around desired turf is important. The directions call for a calm, dry day above 60°F and no rain forecast for 24 hours.

Skip it if you need selective control across lawn weeds without harming grass; Spectracide Weed Stop for Lawns Concentrate 40 Oz is labeled not to harm lawns when used as directed.

Spruce fits buyers removing isolated weeds from areas where contact with wanted plants can be controlled. Its wand and fast visible response suit targeted work, but its non-selective action makes broad lawn spraying unsuitable.
