Best Post Emergent Weed Killer For Lawns: Compare 10 Options

#1 · Best Overall

1. BASF Drive XLR8

• Weight: 4.2 lb
• Form: Liquid

Best for: Crabgrass and mixed-weed control.

Why it ranks #1: Targets crabgrass and broadleaf weeds, with up to 30 days of residual control and rainfastness in less than an hour.

A water-based quinclorac concentrate pairs faster plant uptake with up to 30 days of residual control, giving lawn owners a post-emergent option for crabgrass and a range of other weeds. Its rainfast timing—less than an hour—also offers a practical window for planning applications around weather.

The water-based formulation is described as supporting faster plant uptake, which may help the treatment begin working sooner after application. Up to 30 days of residual control can reduce how often you need to reapply for continuing weed pressure. Because it is a liquid concentrate, application requires mixing rather than using a ready-to-spray bottle. The listed rainfast interval is less than an hour, but the product still calls for careful handling as a herbicide.

Skip it if you want a ready-to-spray format; BioAdvanced Season Long Weed Control For Lawns comes ready to spray and lists up to six months of protection.

Choose this concentrate if crabgrass control, faster plant uptake, and residual activity are priorities for your lawn. It requires mixing, and the listed control window is up to 30 days rather than a season-long prevention claim.

#2 · Warm-Season Turf

2. Envu Celsius WG

• Weight: 18.14 g
• Form: Powder

Best for: Warm-season turf weed control.

Why it ranks #2: Its three active ingredients target more than 120 weeds in warm-season turf, including St. Augustinegrass and Bermudagrass.

Three active ingredients give Celsius WG broad post-emergent coverage, including more than 120 annual and perennial broadleaf weeds and grasses. Its stated fit for warm-season turf such as St. Augustinegrass and Bermudagrass makes it relevant to those lawns, while the easy-mix packet is the supplied application format.

Celsius WG is a foliar-applied herbicide, so its listed post-emergent role is to treat weeds after they have emerged rather than prevent them beforehand. The three active ingredients support broad-spectrum control across more than 120 annual and perennial weeds. Named warm-season turf types include St. Augustinegrass and Bermudagrass, helping buyers assess basic lawn compatibility. The easy-mix packet and product label are included; the supplied facts do not specify a coverage area or application rate.

Skip it if you need a stated coverage area or a granular spread-on product; Scotts Weed Control for Lawns is a granular option with listed broadleaf targets.

This fits buyers treating weeds in compatible warm-season turf who want a foliar-applied post-emergent product with broad listed control. Check the product label for application details, since the supplied information gives no coverage area or rate.

#3 · Broad Turf Fit

3. Monterey Spurge Power

• Weight: 8 oz

Best for: Spurge and violet lawn control.

Why it ranks #3: Lists control of spurge and other broadleaf weeds and use on both warm- and cool-season lawns, across several named grass types.

Three active ingredients target difficult broadleaf weeds including spurge, wild violet, creeping Charlie, and oxalis, making Monterey Spurge Power a focused choice for mixed lawn weeds. Its listed compatibility spans warm- and cool-season lawns, including bluegrass, fescue, bermudagrass, and zoysia.

The product names both common targets such as dandelion and clover and harder-to-control weeds such as spurge, creeping Charlie, and wild violet. Its warm- and cool-season lawn list includes bluegrass, fescue, ryegrass, bentgrass, bahiagrass, bermudagrass, and zoysia, giving buyers several specific compatibility points to check. The concentrated formula comes with a measuring spoon, supporting measured preparation. The supplied facts do not specify a coverage figure, so consult its label for application details.

Skip it if you need a stated lawn coverage area and ready-to-spray application; BioAdvanced Season Long Weed Control For Lawns lists 9,000 square feet and comes ready to spray.

Choose this concentrated option if spurge or other listed difficult broadleaf weeds are present and your turf is among the named compatible grasses. Confirm label directions for coverage and application, since no coverage figure is supplied here.

#4 · Broad Weed List

4. Liquid Harvest Mesotrione

• Weight: 8 oz
• Form: Liquid

Best for: Mesotrione lawn flexibility.

Why it ranks #4: Mesotrione targets 46 listed broadleaf species and grasses, including crabgrass, clover, and dandelion, with water activation required.

Mesotrione provides both pre- and post-emergent activity in a compact 8-ounce concentrate, giving lawn owners a flexible approach to listed grasses and broadleaf weeds. The product names 46 target species and several compatible turf types, while its activation directions make water availability an important part of planning.

The listed targets include crabgrass, clover, chickweed, and dandelion, so the concentrate addresses both grassy and broadleaf weeds. It is identified as suitable for several turf types, including Kentucky bluegrass, centipede grass, buffalo grass, and tall fescue. Mesotrione absorbs upon application, but full weed death may take two to three weeks. Water activates the treatment; if rain does not arrive within ten days, the supplied directions call for 0.15 inches of water.

Skip it if you want a spray-ready product that also lists long residual prevention; BioAdvanced Season Long Weed Control For Lawns is ready to spray and lists up to six months.

This suits lawn owners seeking mesotrione coverage across listed grassy and broadleaf weeds and compatible turf types. Allow two to three weeks for full weed death, and plan for water activation if rainfall does not occur within ten days.

#5 · Dual-Season Action

5. Atticus Torocity

• Weight: 8 oz
• Form: Liquid

Best for: Mesotrione for new or established turf.

Why it ranks #5: The 40.0% mesotrione concentrate has both pre- and post-emergent activity for grassy and broadleaf weeds in new or established turf.

Torocity contains 40.0% mesotrione and offers both pre- and post-emergent activity, extending its stated use to newly seeded as well as established turf. The included pre-marked syringe supports measuring the concentrate, while its dual timing gives buyers flexibility across weed-control stages.

The mesotrione concentrate is described as combining pre-emergent prevention with post-emergent weed control, so it can address weeds before and after emergence. Its stated suitability for newly seeded areas as well as established turf is useful for buyers managing different lawn stages. A pre-marked syringe is included to make measuring easier. This is an 8-ounce liquid concentrate, so application involves measuring the amount needed; use the product label for the correct rate and directions.

#6

6. BioAdvanced Season Long

• Weight: 2.3 lb
• Form: Oil

Best for: Ready-to-spray residual prevention.

Why it ranks #6: Combines post-emergent control of existing weeds with prevention of listed weeds for up to six months in established lawns.

A ready-to-spray 2-in-1 formula kills existing listed weeds and prevents listed weeds from emerging for up to six months. BioAdvanced also lists rainproof protection in one hour, making it a fit for buyers seeking post-emergent control alongside residual prevention in established lawns.

The formula targets existing broadleaf weeds such as dandelion, dollarweed, and clover while also preventing listed weeds from emerging. The ready-to-spray format removes concentrate mixing from the stated workflow, and the listed coverage is up to 9,000 square feet. For prevention, supplied guidance says to spray the entire area, wait at least one hour, then water in to create a weed barrier. Application is listed for established lawns from spring through fall at 50 to 90 degrees Fahrenheit.

Skip it if you are treating newly seeded turf; Atticus Torocity Mesotrione is listed for pre- and post-emergent use in newly seeded as well as established turf.

#7

7. Jonathan Green Lawn Weed Control

• Weight: 0.27 g
• Form: Granule

Best for: Granular broadleaf spot treatment.

Why it ranks #7: The granular post-emergent product controls over 200 broadleaf weeds, but it does not kill crabgrass.

Control of more than 200 broadleaf weeds is the defining feature of Jonathan Green Lawn Weed Control, a granular post-emergent treatment for visible weeds. Its clear limitation—no crabgrass control—helps buyers decide whether their lawn problem matches its target before choosing an application approach.

Because this is a post-emergent product, the supplied information says to spread it only where weeds are visibly present; it is not a pre-emergent treatment. The granular form suits a buyer who prefers spreading product rather than mixing a liquid concentrate. Its broadleaf list includes dandelions, chickweed, oxalis, poison ivy, and thistle. Since crabgrass is a grassy weed and is specifically excluded, this is a poor match when grassy weed control is the main need.

Skip it if you need crabgrass control; BASF Drive XLR8 Crabgrass Killer is a quinclorac concentrate listed for crabgrass and broadleaf weeds.

Choose this granular option when visible broadleaf weeds are the problem and spreading a treatment fits your routine. It is not a pre-emergent product, and lawns with crabgrass need a different weed-control match.

#8

8. Southern Ag Amine 2,4-D

• Weight: 16 oz
• Form: Liquid

Best for: Broadleaf weeds and woody plants.

Why it ranks #8: This liquid 2,4-D concentrate controls many broadleaf weeds and woody plants and is listed for use on certain grasses in lawns.

Southern Ag Amine 2,4-D targets many broadleaf weeds and woody plants, making its liquid concentrate relevant beyond a typical lawn-only weed list. Its stated uses include certain grasses in lawns, parks, golf courses, and pastures, alongside fences and ditch banks, for buyers managing varied sites.

The low use rate is listed as one to four pints per acre, so buyers should follow the label and match application to the intended area. This is a liquid concentrate containing 2,4-D in a low-volatile amine form. Its listed sites extend from lawns and parks to pastures, fences, and ditch banks, offering multi-site utility. The supplied caution specifically advises accurate coverage without overlap and avoiding drift to susceptible plants, making careful spraying important.

Skip it if you want granular weed control combined with lawn fertilizer; The Andersons Professional Surge Weed and Feed combines post-emergent control with 16-0-9 fertilizer.

Consider this liquid concentrate if your weed-control work includes lawn and non-lawn sites such as pastures or ditch banks. Its label calls for accurate coverage without overlap and avoiding drift, so careful spraying is essential.

#9

9. Scotts Weed Control

• Weight: 14.1 lb
• Form: Granule

Best for: Granular broadleaf lawn control.

Why it ranks #9: The granular formula controls over 200 listed broadleaf weeds, but restrictions exclude several grasses, including Floratam St. Augustinegrass.

Scotts Weed Control for Lawns starts working on contact and targets more than 200 listed broadleaf weeds, including dandelion, clover, and dollarweed. The granular format gives lawn owners a spread-on option, but the listed turf exclusions and clover restriction make compatibility a key selection step.

Its broadleaf weed list includes chickweed, poison ivy, henbit, oxalis, ground ivy, and purslane, giving buyers a substantial set of named targets. The product is described as killing weeds down to the root and starting on contact. It is granular, so it is applied by spreading rather than mixing a liquid. The supplied directions say not to wash product from weed leaves for one to two days, followed by thorough watering. Do not use it on the specified sensitive turf types or where desirable clovers are present.

Skip it if you have one of the listed sensitive turf types or want to retain desirable clover; Monterey Spurge Power lists warm- and cool-season lawn compatibility.

This granular treatment fits buyers targeting listed broadleaf weeds in compatible residential lawns. Avoid it on the excluded turf types or where desirable clover is present, and follow the stated interval before washing product from weed leaves.

#10

10. The Andersons Surge Weed and Feed

• Weight: 40 lb
• Form: Granule

Best for: Weed control plus lawn feeding.

Why it ranks #10: This post-emergent granular weed-and-feed covers up to 16,000 square feet but excludes Floratam St. Augustinegrass and several other turf types.

A four-way post-emergent weed-and-feed combines broadleaf weed control with 16-0-9 fertilizer, letting buyers address weeds and lawn feeding in one granular product. It covers up to 16,000 square feet and lists more than 250 common weeds, but its turf exclusions are important to check first.

The fertilizer component is presented as supporting thicker, greener lawns while the herbicide targets more than 250 common weeds, including dandelions, clover, chickweed, and plantain. Small particles are described as providing more coverage per square inch. For application, the supplied guidance says to spread on a damp lawn so granules stick to weed leaves; it also recommends mowing one to two days beforehand and hydrating the grass. It is not for Floratam St. Augustine, dichondra, carpetgrass, or creeping bentgrass.

Skip it if you have Floratam St. Augustine or another excluded turf type; Monterey Spurge Power lists several warm- and cool-season lawns, including bermudagrass and zoysia.

This granular weed-and-feed suits established lawns needing broadleaf control and fertilizer in the same application. Check turf compatibility carefully, and plan to apply it to a damp lawn so granules can adhere to weed leaves.
