Best Grassy Weed Killer For Bermuda: Compare 8 Formulas

Best Grassy Weed Killer For Bermuda

A strong choice for grassy weeds in a Bermuda lawn must control the target weeds while being labeled for use on Bermuda; Celsius WG is the clearest fit in this lineup. The products here are not interchangeable: some are described for warm-season turf, while several fluazifop products target grassy weeds around ornamentals and landscapes. Ortho Grass B Gon explicitly lists bermudagrass among the weeds it controls, making it a better fit when the goal is removing Bermuda from beds rather than preserving a Bermuda lawn.

This roundup compares eight formulas by their listed uses, active ingredients where provided, and formats. Check each current product label for turf compatibility, target weeds, mixing directions, and application limits before spraying, especially where desirable Bermuda grass or nearby ornamentals could be affected.

For a Bermuda lawn where you want to control grassy weeds without harming the turf, Prime Source Celsius WG is the strongest match in this lineup: its description says Celsius controls grasses in warm-season turf types, including Bermudagrass. It is a powder packet, so follow the label for mixing and target weeds. If instead you want to remove Bermuda grass from landscape beds, Ortho Grass B Gon explicitly lists bermuda as a controlled weed and is ready to use.

Confirm the label fits your exact site before applying.

Detailed Reviews: Best Grassy Weed Killer For Bermuda

Prime Source Celsius WG

#1 · Best Overall

1. Prime Source Celsius WG

  • Weight: 18.14 g
  • Form: Powder

Best for: Warm-Season Turf Broad Spectrum.

Why it ranks #1: Its description specifically names Bermudagrass among warm-season turf types where it controls a broad spectrum of weeds; the packet is a compact mixing format.

Celsius WG contains three active ingredients and is described as controlling more than 120 annual and perennial broadleaf weeds and grasses, enabling broad post-emergent treatment in warm-season turf. Bermudagrass is among the listed turf types, making the product relevant to bermuda-lawn weed management.

This powder is a post-emergent, foliar-applied herbicide, so its listed use centers on treating weeds after emergence through application to foliage. The description says it controls more than 120 annual and perennial broadleaf weeds and grasses in warm-season turf types, including Bermudagrass. That broad target range may suit a lawn with mixed weed concerns, rather than someone seeking only a narrowly identified grassy-weed product. The listing includes an easy-mix packet and product label; follow label directions for use.

Pros
  • Post-emergent, foliar-applied formulation
  • Contains three active ingredients
  • Controls more than 120 annual and perennial weeds
  • Listed for warm-season turf including Bermudagrass
Cons
  • The supplied details do not identify specific grassy weed species by name.

Skip it if you need a named grass target on the listing; Ortho Grass B Gon lists bermuda, crabgrass, and tall fescue.

Celsius WG suits warm-season turf owners seeking post-emergent coverage across broadleaf weeds and grasses, including in Bermudagrass. Its supplied information gives broad weed counts rather than a named grass-weed list, so check the label for your target.

Bug And Blade Celsius WG

#2 · Seasonal Two-Pack

2. Bug And Blade Celsius WG

  • Weight: 12.75 g
  • Form: Granule

Best for: Two-Treatment Warm-Season Plan.

Why it ranks #2: The two-pack claims two treatments covering up to 4,000 square feet and control of 120-plus weeds, including crabgrass; confirm Bermuda compatibility on its label.

Bug And Blade’s Celsius WG two-pack includes two treatments and an identification card, enabling a planned spring-and-fall weed-control cycle with a tool for identifying weeds. The listing says the pair covers up to 4,000 square feet and targets more than 120 weeds, including crabgrass.

Each packet is described as providing two gallons for an application, with one packet intended for early spring and the second for late summer or fall. That schedule gives warm-season turf owners a defined two-treatment program from green-up through dormancy. The listing names Bermudagrass among the warm-season turf types and includes crabgrass, dollarweed, and clover in its weed examples. It claims coverage up to 4,000 square feet; use the included weed ID card and follow the label for application directions.

Pros
  • Two packets support a spring-and-fall treatment cycle
  • Listing states coverage up to 4,000 square feet
  • Targets more than 120 weeds, including crabgrass
  • Includes a Bug And Blade weed identification card
Cons
  • The listed program provides two seasonal applications, not additional treatments.

Skip it if you need a ready-to-use spray for spot work; Ortho Grass B Gon Garden Grass Killer is listed as ready to use.

Choose this Celsius WG pack for a warm-season turf owner planning two seasonal applications and wanting an included weed identification card. Its coverage is listed up to 4,000 square feet, so match the package plan to your area.

Ortho Grass B Gon

#3 · Ready-to-Use Spray

3. Ortho Grass B Gon

  • Weight: 1.5 lb
  • Form: Spray

Best for: Ready-To-Use Garden Spray.

Why it ranks #3: Its listed targets explicitly include bermuda, and the ready-to-use spray is described for use around landscape plants, ground covers, shrubs, and trees.

Ortho Grass B Gon arrives ready to use in a spray format and lists bermuda among its target grassy weeds, enabling direct treatment without concentrate mixing. The product is intended for use in and around ground covers, plant beds, landscapes, shrubs, and trees.

The ready-to-use format avoids a separate dilution step, which can simplify spot treatment around garden plantings. Its listed target weeds include bermuda, crabgrass, tall fescue, annual bluegrass, and Kentucky bluegrass, giving buyers named targets to compare with their lawn or beds. The product is described as not harming landscape plants when used as directed and is rainfast one hour after application. The listing is a two-pack of 24-ounce sprays; follow label instructions and avoid application before expected rain.

Pros
  • Ready-to-use spray requires no concentrate mixing
  • Lists bermuda among its target weeds
  • For use around ground covers, beds, shrubs, and trees
  • Rainfast one hour after application
Cons
  • The listed two-pack is a ready-to-use spray, not a concentrate for tank mixing.

Skip it if you prefer a concentrate and tank-mix workflow; Gordon’s Ornamec 170 is a water-mixed concentrate labeled for landscape beds.

Ortho Grass B Gon fits buyers treating listed grassy weeds such as bermuda around garden plantings who want a ready-to-use spray. Its application is not a concentrate tank-mix routine, and rain timing should follow the label.

Atticus Vendra II SRX

#4 · Compact Fluazifop

4. Atticus Vendra II SRX

  • Weight: 5.44 oz
  • Form: Liquid

Best for: Compact Fluazifop Concentrate.

Why it ranks #4: The 4-fluid-ounce bottle contains 24.5% fluazifop-p-butyl and targets grassy weeds selectively, but the supplied facts do not confirm Bermuda turf safety.

Atticus Vendra II SRX comes in a 4-fluid-ounce bottle with a Tip N’ Measure pouring feature, enabling users to measure and pour the concentrate without handling a larger package. Its 24.5% fluazifop-p-butyl formula selectively targets grassy weeds, including bermudagrass, according to the product title.

The 4-fluid-ounce size is described as easy to store, which suits buyers who want a compact bottle rather than a larger package. Atticus also identifies a Tip N’ Measure bottle for measuring and pouring, supporting a more controlled preparation workflow. Its 24.5% fluazifop-p-butyl active ingredient is described as selectively targeting grassy weeds without damaging desirable grass and ornamental plants. Read and follow the label for complete application directions before use.

Pros
  • 24.5% fluazifop-p-butyl active ingredient
  • Product title identifies bermudagrass as a target
  • Tip N’ Measure feature supports measuring and pouring
  • Compact 4-fluid-ounce bottle is described as easy to store
Cons
  • The 4-fluid-ounce bottle provides less concentrate than a larger-format option.

Skip it if you want a ready-to-use spray rather than concentrate; Ortho Grass B Gon Garden Grass Killer is listed as ready to use.

Vendra II SRX suits buyers seeking a compact fluazifop concentrate for grassy weeds, including bermudagrass named in its title. It is a fit when measuring concentrate is acceptable; application details remain label-directed.

Syngenta Fusilade II

#5

5. Syngenta Fusilade II

  • Weight: 4 oz
  • Form: Liquid

Best for: Landscape And Nursery Use.

Why it ranks #5: This 4-ounce liquid contains 24.5% fluazifop-p-butyl and targets annual and perennial grasses in turf and landscapes; check the label for Bermuda use.

Syngenta Fusilade II combines 24.5% fluazifop-P-butyl with selective post-emergent control, enabling treatment of listed annual and perennial grass weeds in turf and landscape settings. The supplied description also identifies nurseries and sports fields, while stating that ornamentals can be protected during weed control.

Its selective post-emergent action targets perennial and annual grass weeds, so the product is intended for weeds that have emerged rather than a pre-emergent application. The 24.5% fluazifop-P-butyl concentrate comes in a 4-ounce bottle, a compact format for users who need a small package. The listing says it can be applied over the top or as a directed spray and identifies landscapes, nurseries, and sports fields as settings. Follow the product label for application directions.

Pros
  • 24.5% fluazifop-P-butyl active ingredient
  • Targets perennial and annual grass weeds
  • Listed for landscapes, nurseries, and sports fields
  • Can be applied over the top or as a directed spray
Cons
  • The listed bottle contains only 4 ounces of concentrate.

Skip it if you need a ready-to-use spray; Ortho Grass B Gon Garden Grass Killer is listed as ready to use.

Fusilade II fits buyers managing emerged grass weeds in landscape, nursery, or sports-field settings who want selective post-emergent treatment. The 4-ounce concentrate requires label-directed preparation, and its use must match the target site.

Gordon's Ornamec 170

#6

6. Gordon's Ornamec 170

  • Weight: 2 lb
  • Form: Spray

Best for: Landscape Bed Maintenance.

Why it ranks #6: Its fluazifop formula is intended for landscape beds and listed ornamental settings, making it more suited to grassy weeds near ornamentals than a Bermuda lawn.

Over-the-top application around ornamental plants is the defining feature of Gordon’s Ornamec 170, letting landscape-bed caretakers target actively growing grass weeds while treating listed ornamentals. Its label describes use around groundcovers, shrubs, trees, and flowers, making it a fit for mixed plantings where placement matters.

The 1.70% fluazifop-P-butyl formula is mixed with water, and the listed rate is 10 ounces per gallon. That concentrate format lets users prepare a spray for the area being treated rather than handle a ready-to-use bottle. The product is labeled for ornamental plants, groundcovers, shrubs, trees, landscape beds, ornamental beds, and fence lines. Follow the provided directions and treat actively growing grass weeds before they exceed recommended growth stages; use caution around ornamentals.

Pros
  • Labeled for use around ornamental plants and groundcovers
  • Can be applied over the top of listed ornamentals
  • Covers landscape beds, shrubs, trees, and fence lines
  • Mixes at a listed rate of 10 ounces per gallon
Cons
  • Requires dilution and careful timing around actively growing grass weeds.

Skip it if you need a ready-to-use spray; Ortho Grass B Gon Garden Grass Killer comes ready to apply in its listed spray form.

Choose Ornamec 170 for landscape-bed maintenance when you need a concentrate labeled for use around ornamentals and other listed plantings. Its fit depends on mixing, label-directed timing, and careful application around ornamental plants.

BASF Drive XLR8

#7

7. BASF Drive XLR8

  • Weight: 4.2 lb
  • Form: Liquid

Best for: Extended Residual Lawn Control.

Why it ranks #7: This 64-ounce quinclorac concentrate targets crabgrass and other weeds with up to 30 days of residual control, but the supplied facts do not establish Bermuda compatibility.

BASF Drive XLR8 lists up to 30 days of residual control and rainfastness in less than an hour, enabling a treatment schedule with a stated persistence window and a short rainfast interval. Its water-based formulation is also described as supporting faster plant uptake.

The 64-ounce concentrate is a fit for buyers preparing lawn or turf treatments rather than selecting a small ready-to-use sprayer. BASF describes its water-based formulation as providing faster plant uptake, while the listed residual control lasts up to 30 days; together, those features support a treatment with both quick uptake and continued residual activity. The product is also rainfast in less than an hour. Its active ingredient is quinclorac, and label directions should guide mixing and application.

Pros
  • Water-based formulation is described as supporting faster plant uptake
  • Up to 30 days of residual control
  • Rainfast in less than an hour
  • 64-ounce concentrate format for lawn and turf use
Cons
  • The 64-ounce concentrate requires mixing before application.

Skip it if you need a small concentrate bottle; Syngenta Fusilade II is listed in a 4-ounce bottle for grass-weed control.

Drive XLR8 suits lawn and turf users who value the stated residual period and rainfast interval in a concentrate. Its 64-ounce format calls for mixing, and buyers should check the label for target weeds and application directions.

Monterey Turflon Ester

#8

8. Monterey Turflon Ester

  • Weight: 8 oz
  • Form: Liquid

Best for: Spray-Tank Application.

Why it ranks #8: The listing provides little evidence for grassy-weed control or Bermuda turf use and warns that spray drift can damage flowerbeds and other non-target broadleaf plants.

Monterey Turflon Ester is diluted with water and applied using a spray tank, giving buyers a concentrate workflow for planned spraying rather than a ready-to-use bottle. Its supplied safety information makes flowerbed protection a central consideration: spray drift can damage flowerbeds and other non-target broadleaf plants.

The listed directions call for diluting Turflon Ester with water and applying it using a spray tank. That workflow suits someone who already plans to mix and apply a tank spray, but requires preparation rather than direct application from the container. The safety information specifically warns against spray drift reaching flowerbeds or other non-target broadleaf plants because damage will occur. The supplied product details do not specify a target weed list, so consult its label before selecting it for a particular grassy weed.

Pros
  • Liquid concentrate is diluted with water
  • Directions specify application using a spray tank
  • Safety information clearly flags drift-sensitive plants
  • Compact 8-ounce listing is easy to handle
Cons
  • Spray drift can damage flowerbeds and other non-target broadleaf plants.

Skip it if you need a listed target-weed match before buying; Syngenta Fusilade II names perennial and annual grass weeds.

Consider Turflon Ester if a water-diluted spray-tank workflow suits your application routine. Its supplied details emphasize drift precautions rather than a target weed list, so verify label suitability and protect flowerbeds and other broadleaf plants.

Avoid confusing Bermuda control with Bermuda-lawn care

The key mistake is treating a product that kills Bermuda as a safe choice for a Bermuda lawn. Ortho Grass B Gon specifically lists bermuda among the weeds it controls, while Prime Source Celsius WG is described for controlling weeds in warm-season turf types that include Bermudagrass. Those are different jobs: removing unwanted Bermuda from a bed is not the same as suppressing grassy weeds while preserving Bermuda turf.

Several fluazifop products in this roundup are positioned for grassy weeds in ornamental or landscape settings, but their supplied details do not establish that they are safe on a Bermuda lawn. Do not infer turf safety from words such as selective or grass herbicide.

Identify whether Bermuda is the target or the desirable turf, then verify the product label covers that exact use, site, and weed.

Match the package format to the application site

A ready-to-use bottle and a concentrate require different preparation, so package format is a practical compatibility check before choosing. Ortho Grass B Gon is listed as ready to use, while Prime Source Celsius WG comes as a powder packet and Gordon’s Ornamec 170 is a concentrate with a listed mix rate of 10 ounces per gallon of water. Atticus Vendra II SRX also comes in a small 4-fluid-ounce bottle, with a Tip N’ Measure feature noted in the supplied details.

These formats do not establish how much area a treatment covers; that depends on label directions and the application rate. For small, isolated landscape patches, a ready-to-use format may avoid mixing.

For broader treatment, verify the label’s coverage and mixing instructions rather than estimating from bottle size.

How to Choose a Grassy Weed Killer for Bermuda

Whether Bermuda is turf or the target

First decide whether you want to protect Bermuda turf or kill Bermuda growing as an unwanted grass. Prime Source Celsius WG is described for warm-season turf that includes Bermudagrass, whereas Ortho Grass B Gon lists bermuda among its controlled weeds and is intended for use around landscape plants. That distinction outweighs package size or convenience.

If your lawn is Bermuda, prioritize a label that explicitly permits use on Bermudagrass and lists the weed you want to control. If Bermuda is invading a bed, consider a product labeled for that landscape setting and target.

The supplied descriptions do not establish the safe use of every product on Bermuda turf, so verify the current label before treating.

Target weeds and active ingredient

Look for a product whose listed target weeds match the problem and whose label supports your site. Atticus Vendra II SRX and Syngenta Fusilade II each list 24.5% fluazifop-p-butyl, while Gordon’s Ornamec 170 lists 1.70% fluazifop-P-butyl. Celsius is described as controlling more than 120 weeds, and the Bug And Blade package names crabgrass among its targets.

BASF Drive XLR8 contains quinclorac and is positioned for crabgrass and other weeds. These claims describe different products and uses, not interchangeable results.

A buyer treating a broad selection of weeds in warm-season turf should investigate Celsius; someone targeting unwanted grass in ornamental beds should consider the landscape-oriented fluazifop products, subject to label approval.

Format, mixing, and treatment quantity

Choose a format you can apply according to its label, rather than assuming the largest package covers the most area. Ortho Grass B Gon is ready to use, Celsius WG is sold as a powder packet, and the supplied directions for Ornamec 170 give a mixing rate of 10 ounces per gallon of water. BASF Drive XLR8 is a 64-ounce concentrate, while Atticus Vendra II SRX is a 4-fluid-ounce bottle.

The Bug And Blade Celsius WG listing claims two treatments for up to 4,000 square feet, a specific coverage claim not supplied for most other products. Small, isolated patches may favor a ready-to-use format; repeat or larger treatments may make a concentrate or multipack worth considering, but check label rates and coverage first.

Which Grassy Weed Killer Should You Choose for Bermuda?

For grassy weeds in a Bermuda lawn, start with Prime Source Celsius WG: its description specifically includes Bermudagrass among compatible warm-season turf types. Bug And Blade Celsius WG is another option to investigate if you want the listed two-treatment package and its claim of coverage up to 4,000 square feet; verify that its label covers your site and target weeds. If Bermuda itself is unwanted in a landscape bed, Ortho Grass B Gon explicitly lists bermuda as a target and is ready to use.

For grassy weeds near ornamental plantings, Gordon’s Ornamec 170 or Atticus Vendra II SRX may suit the setting described, but do not assume either is safe on Bermuda turf. Match the label to the precise target and application site before treating.

Frequently Asked Questions

Which grassy weeds can be controlled in a Bermuda lawn without injuring the turf?

Prime Source Celsius WG is the strongest match in this lineup because its description says it controls grasses in warm-season turf, including Bermudagrass. Bug And Blade Celsius WG is another option to investigate, but check its label for your exact site and target weeds. Do not assume other grass herbicides are safe on Bermuda turf.

When should I apply grassy weed killer to Bermuda grass?

Apply only when the product label permits treatment for your Bermuda lawn and the target weed. Check the label for timing, weather, turf conditions, mixing, and any restrictions; these can differ by product. Celsius WG is a powder packet, so follow its label for preparation and application rather than guessing at a rate.

How can I prevent spray drift from damaging nearby ornamentals or flowerbeds?

Follow the product label’s drift precautions and avoid spraying when conditions could carry spray onto nearby plants. Keep the application directed at the intended weeds, use only the labeled method, and do not treat around ornamentals unless the label permits that site. Ornamec 170 and Vendra II SRX may suit described ornamental settings, but do not assume they are safe on Bermuda turf.

Can I use a grass killer to remove Bermuda from a landscape bed?

Ortho Grass B Gon is the clearest match here for that purpose: its description explicitly lists bermuda as a controlled weed and says it is ready to use. Confirm that its label covers your exact landscape-bed site and intended target before applying, and protect nearby plants according to the label.

What should I check before choosing a product for my lawn?

Verify that the label names your turf type, target weed, and application site. For Bermuda lawns, Prime Source Celsius WG is the lineup’s strongest stated match; Bug And Blade Celsius WG is another option to investigate. Check package directions and coverage claims on the label, and do not infer turf safety from a product’s general grass-control wording.

Final Words

For grassy weeds in a Bermuda lawn, start with Prime Source Celsius WG because its description specifically includes Bermudagrass among compatible warm-season turf types. Bug And Blade Celsius WG is another option to investigate, with its listed two-treatment package and coverage claim; verify label fit first. If Bermuda itself is unwanted in a landscape bed, consider ready-to-use Ortho Grass B Gon.

In every case, match the label to the target and site.
