Best Post Emergent For Centipede Grass: 10 Options Compared

#1 · Best Overall

1. Southern Ag Atrazine Weed Killer

• Weight: 2.1 lb
• Form: Spray

Best for: Centipede atrazine spray.

Why it ranks #1: Its listed use explicitly includes centipede grass, and the description says it controls emerged weeds and weeds from seed; one quart treats 3,720 square feet.

Southern Ag lists centipede grass among the lawns suitable for this atrazine herbicide, making it a direct fit for owners treating that turf type. The spray controls emerged weeds and weeds from seed, combining visible-weed treatment with suppression of future growth in one specialty product.

The product controls many common grassy and broadleaf weeds, and its description specifically notes suppression of crabgrass. Because it addresses both emerged weeds and weeds from seed, it can serve buyers looking beyond weeds already visible in the lawn. One quart treats 3,720 square feet, giving a practical coverage reference for planning an application. Its labeled use includes both St. Augustine and centipede lawn grasses; follow the label directions for application.

Skip it if you want mesotrione for a broader listed target range; Liquid Harvest Mesotrione 8oz targets 46 broadleaf weeds and grasses.

Centipede lawn owners seeking a spray that addresses emerged weeds as well as weeds from seed will find a relevant fit here. Use the 3,720-square-foot coverage figure to plan treatment, and follow label directions.

#2 · Best Turf Match

2. Liquid Harvest Mesotrione

• Weight: 8 oz
• Form: Liquid

Best for: Centipede mesotrione concentrate.

Why it ranks #2: The product lists centipede grass as suitable turf and targets 46 broadleaf species and grasses; it is a liquid concentrate.

Mesotrione is labeled for centipede grass and 46 broadleaf weeds and grasses, giving lawn owners one concentrate for varied targets. Its pre- and post-emergent role supports both prevention and treatment, while the liquid form suits measured spray application rather than spreading granules across the lawn.

The listed targets include crabgrass, clover, chickweed, and dandelion, which helps when a lawn has a mix of grassy and broadleaf weeds. Mesotrione absorbs upon application, but full weed death may take two to three weeks, so it is not an instant visual fix. Water is required for activation; if rain does not arrive within 10 days, the directions specify applying 0.15 inches of water. The 8-ounce concentrate is a small-format option for spray use.

Skip it if you need a granular feed-and-weed application; The Andersons Surge combines weed control with lawn fertilizer.

Centipede owners seeking a liquid mesotrione treatment for mixed grassy and broadleaf weeds should consider this concentrate. Allow for the stated two-to-three-week window for full weed death, and provide water for activation when rainfall is absent.

#3 · Surfactant Included

3. Liquid Harvest Mesotrione Bundle

• Weight: 8.32 oz
• Form: Liquid

Best for: Mesotrione with surfactant bundle.

Why it ranks #3: It lists centipede grass as suitable and targets broadleaf and grassy weeds; the bundle includes an 8-ounce surfactant alongside the concentrate.

This Liquid Harvest bundle pairs 8 ounces of mesotrione concentrate with an 8-ounce surfactant, giving buyers both components for a spray-treatment setup. The mesotrione is listed for centipede grass and targets 46 broadleaf weeds and grasses, supporting use across a varied weed mix.

The concentrate acts as both a pre- and post-emergent weed killer, while its listed targets include crabgrass, clover, chickweed, and dandelion. The included surfactant adds a second component to the bundle for the spray workflow. Mesotrione begins working upon application, but full weed death may take two to three weeks. Water is required for activation; if rainfall does not occur within 10 days, the supplied directions specify 0.15 inches of water.

Skip it if you already have a surfactant and want only mesotrione concentrate; Liquid Harvest Mesotrione 8oz is the concentrate-only option.

Centipede owners seeking mesotrione plus a surfactant for spray treatment may prefer this bundle. Allow time for full weed death, and account for the water-activation directions when rainfall is not expected.

#4

4. Atticus Torocity Mesotrione

• Weight: 8 oz
• Form: Liquid

Best for: Flexible mesotrione lawn treatment.

Why it ranks #4: Its 40.0% mesotrione formula offers pre- and post-emergent activity, though supplied details do not specifically confirm centipede grass suitability.

Torocity contains 40.0% mesotrione and offers both pre- and post-emergent activity, giving lawn owners flexibility to address weeds before and after emergence. Its description identifies use on newly seeded areas as well as established turf, broadening its fit across different lawn stages.

The same active ingredient, mesotrione, supports both pre-emergent prevention and post-emergent weed control, so buyers can work with either timing need. The product is described for newly seeded areas and established turf, an important distinction for lawns at different stages. A pre-marked syringe is included to make measuring the concentrate easier, helping with preparation before application. As an 8-ounce liquid, it is a small-format concentrate; follow label directions for rates and use conditions.

Skip it if you require explicit centipede labeling; Liquid Harvest Mesotrione 8oz specifically lists centipede among suitable turf grasses.

This concentrate suits buyers who want mesotrione’s two timing modes and a measuring syringe, including those treating newly seeded or established turf. Centipede owners should confirm that the label permits use on their grass.

#5 · Extended Residual

5. BASF Drive XLR8

• Weight: 4.2 lb
• Form: Liquid

Best for: Extended-residual crabgrass control.

Why it ranks #5: This liquid quinclorac concentrate targets grassy and broadleaf weeds and lists up to 30 days of residual control, but centipede compatibility is not supplied.

BASF Drive XLR8 lists up to 30 days of residual control, giving buyers a stated period of continued weed control after application. Its water-based formulation is described as supporting faster plant uptake, while the post-emergent concentrate targets grassy and broadleaf weeds in lawns and turf.

The listed rainfast interval is less than an hour, which can help buyers plan around weather after application. A 64-ounce liquid concentrate provides a format for mixing rather than applying ready-to-spread granules. The product is identified for crabgrass control and broader grassy and broadleaf weed control, making it relevant when a lawn problem extends beyond one weed type. The 30-day residual claim may reduce the need for frequent applications, though results depend on following the label.

Skip it if you want a product expressly listed for centipede grass; Liquid Harvest Mesotrione 8oz names centipede among its suitable turf grasses.

Buyers addressing crabgrass and other grassy or broadleaf weeds may value the stated residual period and short rainfast interval. Centipede owners should verify turf suitability on the product label before applying this concentrate.

#6

6. Fertilome Centipede Weed & Feed

• Weight: 16 lb
• Form: Granules

Best for: Centipede weed-and-feed granules.

Why it ranks #6: Its name and supplied application details identify centipedegrass, but the provided facts do not specify post-emergent weed targets or control performance.

The product name identifies Fertilome Centipede Weed & Feed as a 15-0-15 granular formula for centipede lawns, pairing weed-and-feed use with a specified fertilizer analysis. Its 16-pound package suits buyers seeking a lawn-care product in granular form rather than a liquid concentrate.

The 15-0-15 analysis gives buyers a concrete fertilizer specification when comparing lawn formulas, while the granule form supports a spread-based application workflow. Its name specifically identifies centipede use, making that turf type central to the product’s intended fit. The supplied facts do not state coverage, target weed species, or application frequency, so those details cannot be used to plan treatment from this listing alone. Refer to the product label for directions and applicable weeds.

Skip it if you need named weed targets and stated coverage before choosing; Southern Ag 006130 lists centipede use and 3,720-square-foot coverage.

Centipede owners looking specifically for a granular weed-and-feed with a stated 15-0-15 analysis may find this format relevant. The supplied details do not name controlled weeds or coverage, so check the label before planning an application.

#7

7. Nufarm Triplet SF

• Weight: 2 lb
• Form: Liquid

Best for: Selective broadleaf turf treatment.

Why it ranks #7: This post-emergent selective herbicide controls broadleaf weeds and is intended for warm- or cool-season turf, but centipede-specific fit is not stated.

Triplet SF combines three selective herbicides to control a variety of broadleaf weeds, making it a focused choice when grassy weeds are not the primary concern. Its flexible application rates allow higher rates for problem areas and lower rates for turf maintenance across cool- or warm-season turf.

The broadleaf focus helps buyers distinguish this liquid from products aimed at grassy weeds, while the three-herbicide combination supports control across a variety of broadleaf targets. Flexible rates offer an application approach for either localized problem areas or routine turf maintenance. It is identified for cool- and warm-season turf and labeled for sod farm usage, so it can fit both lawn and sod-farm settings. The supplied listing does not name centipede specifically or list individual weed species.

Skip it if you need explicit centipede labeling and named grassy-weed targets; Southern Ag 006130 lists centipede use and grassy weed control.

Triplet SF suits buyers focused on broadleaf weeds across cool- or warm-season turf, including sod-farm use. Centipede owners should check the label for that specific grass and confirm the target weeds before applying.

#8

8. The Andersons Surge Weed and Feed

• Weight: 40 lb
• Form: Granule

Best for: Granular weed-and-feed coverage.

Why it ranks #8: It controls over 250 common weeds as a post-emergent weed-and-feed, but the supplied restrictions do not establish centipedegrass compatibility.

A 40-pound bag covers up to 16,000 square feet while combining post-emergent weed control with 16-0-9 fertilizer. That pairing suits buyers who want to feed established turf and address broadleaf weeds in one granular application, rather than choosing separate weed-control and fertilizer products.

The formula targets more than 250 common weeds, including dandelion, clover, chickweed, and plantain, while its fertilizer is intended to build thicker, greener lawns. Small particles provide more coverage per square inch, supporting distribution across a broad lawn. Application works on damp turf: dew or light watering helps granules stick to weed leaves. The product is for established turf, and its listed exclusions include Floratam St. Augustine, dichondra, carpetgrass, and creeping bentgrass.

Skip it if you need a product expressly listed for centipede grass; Southern Ag 006130 Atrazine is labeled for centipede lawns.

Choose this granular option for established turf when broadleaf weed control and feeding are both on the task list. Centipede buyers should check the label for suitability, and avoid it on the listed excluded grasses.

#9

9. Jonathan Green Lawn Weed Control

• Weight: 0.27 g
• Form: Granule

Best for: Broadleaf-only granular control.

Why it ranks #9: This post-emergent granule controls over 200 broadleaf weeds, but it does not kill crabgrass and the supplied details do not confirm centipede suitability.

Jonathan Green Lawn Weed Control targets more than 200 broadleaf weeds, including dandelions, chickweed, oxalis, poison ivy, and thistle, giving buyers a broad list of named targets. It is post-emergent, so its role is treating visible weeds rather than preventing their emergence.

Because this product should be spread only where weeds are visibly present, buyers can focus treatment on affected areas instead of applying it as a pre-emergent. Its granular form suits a spreading workflow, and the listing states coverage of 15,000 square feet. The broadleaf scope is an important boundary: it will not kill crabgrass, which the listing identifies as a grassy weed. Choose it for visible broadleaf weeds, not a lawn problem centered on crabgrass.

Skip it if you need grassy-weed control including crabgrass; Southern Ag 006130 lists control of common grassy weeds and centipede use.

This granular product fits buyers treating visible broadleaf weeds across a stated 15,000 square feet. Centipede owners should verify turf suitability, and lawns troubled by crabgrass need a different target profile.

#10

10. Agrisel QuinKill Max

• Weight: 16 oz
• Form: Liquid

Best for: Measured liquid weed treatment.

Why it ranks #10: The product provides a mixing rate for 1,000 square feet, but supplied details do not identify its active ingredient, target weeds, or centipedegrass fit.

Agrisel QuinKill Max provides a stated application range of 0.5 to 1.45 fluid ounces per gallon for 1,000 square feet, giving buyers a concrete starting point for measuring treatment. Its liquid form supports mixing for preventative or curative weed-control applications.

The directions call for measuring the area first, then calculating the solution amount from square footage, which helps organize treatment rather than estimating lawn size. The stated rate range offers application guidance for 1,000 square feet, and the product can be mixed for preventative or curative treatment. The listing identifies it as lawn-friendly and pet safe, but also says to keep it away from children and pets and not apply when rain is expected within 24 hours.

Skip it if you need a product with named weed targets and centipede labeling; Southern Ag 006130 lists both centipede use and grassy and broadleaf weed control.

Choose this liquid if measuring lawn area and mixing a calculated treatment suits your workflow. Its supplied directions specify a 24-hour rain-free window, and the listing does not name centipede grass or individual weeds.
