On a bermuda lawn the hard part is not killing crabgrass. Plenty of products will do that. The hard part is killing it without taking the bermuda with it, and that single constraint rules out most of what sits on the shelf under a weed killer sign. Anything labelled as a non selective killer, including the familiar bottles people reach for by habit, will leave brown patches exactly where the crabgrass was. We compared 8 crabgrass killer for bermuda grass options from BASF, Scotts, Gordon’s and more on selectivity, active ingredient, and whether the label actually lists bermuda as a grass it tolerates.
Our top pick is Scotts Halts Crabgrass and Grassy Weed Preventer, because on an established bermuda lawn the cheapest crabgrass to deal with is the crabgrass that never germinates. For the equipment side, our guide to the best lawn and garden sprayers covers applying the liquid concentrates here.
Pros
- Prevention is gentler on turf than killing mature clumps
- Granular form spreads evenly with a broadcast spreader
- Covers a large lawn area per bag
- No spray drift onto beds and ornamentals
Cons
- Does nothing to crabgrass that has already emerged
- Needs watering in, so a dry spell wastes the application
Halts works on the principle that the easiest crabgrass to deal with is the crabgrass that never comes up. Spread before germination, it forms a barrier in the top layer of soil that stops seedlings from establishing.
For a bermuda lawn that is the gentlest available approach, because nothing is being asked to distinguish between two live grasses. A post emergent has to kill one grass while sparing another that is closely related, and that margin is where turf damage comes from. A pre emergent avoids the question entirely.
Two conditions decide whether it works. Timing has to follow soil temperature rather than the calendar, since crabgrass germinates when soil at seed depth holds in the mid fifties Fahrenheit. And granules need water to carry the active into the soil, so a dry week after spreading wastes the pass.
Bottom line: the right first purchase for a bermuda lawn, provided you apply it before germination rather than after.
- Type: pre emergent
- Form: granular
- Size: 10.06 pound bag
- Application: broadcast spreader
- Watering in: required
- Target: crabgrass and grassy weeds at germination
Check soil temperature at seed depth with a soil thermometer and apply as it approaches the mid fifties Fahrenheit, before germination begins.
Water in after spreading if no rain is forecast, and avoid aerating or dethatching afterwards, since disturbing the surface breaks the barrier.
Follow the label rate for your lawn area rather than estimating, and keep the spreader closed while crossing paths and driveways.
Observe the label guidance on keeping people and pets off treated areas until the product has been watered in and the lawn has dried.
Pros
- Quinclorac is the standard active for crabgrass in warm season turf
- Liquid concentrate allows spot treatment
- Effective on clumps a pre emergent missed
- Covers a large area per bottle when mixed correctly
Cons
- Less effective on mature, well tillered crabgrass
- Requires careful mixing and a sprayer
When crabgrass is already in the lawn, a pre emergent has nothing to offer and a selective post emergent is the tool. Drive XLR8 uses quinclorac, which is the active most commonly relied on for crabgrass in warm season turf.
As a concentrate it gives you the option of treating clumps where they are rather than dosing the whole lawn, which is both cheaper and easier on the turf. That flexibility is the main advantage of liquids over granules in the post emergent role.
Two realities to plan around. Crabgrass gets harder to kill as it matures, so a plant that has spread into a wide tillered clump may need a follow up application, and rain within a few hours of spraying can wash the product off the leaf before it is absorbed.
Bottom line: the strongest rescue option here for a bermuda lawn, most effective when the crabgrass is still young.
- Type: post emergent
- Active ingredient: quinclorac
- Form: liquid concentrate
- Application: tank or hand sprayer
- Target: emerged crabgrass and grassy weeds
- Turf: check label for tolerant species and rates
Mix at the labelled rate rather than by eye, since under-dosing produces weak control and over-dosing risks turf injury.
Spray when no rain is expected for several hours, and leave a couple of days either side before mowing so the leaf surface stays intact.
Read the tolerant grass list and rate table together before the first application on any lawn.
Avoid spraying on windy days to prevent drift onto ornamental plants and vegetable beds.
Pros
- Treats crabgrass and broadleaf weeds together
- Concentrate stretches further than ready to use bottles
- Widely stocked and easy to replace
- Suits lawns with mixed weed problems
Cons
- Combination formulas are less targeted than single active products
- Still requires checking turf tolerance on the label
Most lawns do not have only one weed problem. Crabgrass tends to arrive alongside broadleaf weeds, and treating them separately means two mixes, two passes and two products on the shelf.
This concentrate covers both, which is the practical case for it. For a homeowner dealing with a general decline in lawn quality rather than a specific crabgrass invasion, it is the more sensible purchase.
The tradeoff with any combination product is precision. A formulation aimed at several weed types is rarely the strongest option against any single one, so a heavy crabgrass problem may still be better served by a dedicated quinclorac product. Turf tolerance still needs checking on the label regardless of how familiar the brand is.
Bottom line: the right choice when crabgrass is one of several problems rather than the only one.
- Type: post emergent
- Form: liquid concentrate
- Size: 40 ounces
- Targets: crabgrass and broadleaf weeds
- Application: sprayer, mixed to label rate
- Turf: check label tolerance list
Choose this over a single active product when the lawn has dandelions and clover as well as crabgrass.
For a severe crabgrass problem alone, a dedicated quinclorac concentrate is the stronger tool.
Mix only what you will use, and rinse the sprayer thoroughly afterwards so residue does not affect the next application.
Follow label guidance on keeping people and pets off the lawn until the treated area has dried.
Pros
- Three jobs in one pass saves time
- Granular application with no drift
- Feeds the lawn at the same time
- Convenient for a single spring treatment
Cons
- Ideal timing for feeding and prevention rarely coincide
- Less precise than applying each product on its own schedule
Combination bags are popular because they compress a weekend of lawn care into one pass, and that convenience is genuinely worth something to most homeowners.
The catch is scheduling. Crabgrass prevention is timed to soil temperature in late winter, while bermuda wants nitrogen once it is warm and actively growing, which is later in the season. A single product applied once cannot be perfectly timed for both jobs.
That does not make it a bad purchase, it makes it a compromise you should choose deliberately. If your lawn genuinely needs feeding and prevention at the same moment, this is efficient. If the calendars are weeks apart, separate products applied on their own schedules give a better result.
Bottom line: convenience with a real scheduling cost, worth it when the two jobs actually overlap.
- Type: combination feed and weed control
- Form: granular
- Size: 11.31 pound bag
- Functions: prevents crabgrass, controls broadleaf weeds, feeds lawn
- Application: broadcast spreader
- Watering in: follow label guidance
Use it when feeding and prevention timing overlap in your region, and separate the jobs when they do not.
Check the label for whether the lawn should be damp at application, which differs between combination products.
Keep granules off hard surfaces where they can wash into storm drains, and sweep any that land on paths back onto the lawn.
Observe the label interval before allowing pets back onto the treated area.
Pros
- Covers multiple weed types in one product
- Granular form is forgiving to apply
- Feeds while it treats
- Convenient for general lawn upkeep
Cons
- Same timing compromise as any combination bag
- Broad formulations are less potent against a single target weed
This is a general upkeep product rather than a crabgrass specialist, and it is worth reading it that way. It handles several weed types alongside feeding, which suits a lawn that is broadly untidy rather than one with a specific invasion.
Granular application keeps it simple. There is no mixing, no sprayer to rinse and no drift onto beds, which for many homeowners is the deciding factor over a concentrate.
The limitations are the ones every combination product shares. Feeding and weed control timing do not always align, and a formulation spread across five functions is rarely the strongest answer to any one of them. For heavy crabgrass on bermuda, a dedicated selective product does more.
Bottom line: a reasonable routine treatment, not a rescue for a lawn already overtaken by crabgrass.
- Type: combination weed and feed
- Form: granular
- Size: 9.6 pound bag
- Functions: multiple weed control plus feeding
- Application: broadcast spreader
- Turf: check label tolerance list
Homeowners doing routine seasonal lawn care who want one bag rather than several products.
Not the right tool for a lawn where crabgrass has already taken hold across a large area.
Apply at the labelled rate and keep granules off paved surfaces to limit runoff.
Follow the label interval before letting pets and children back on the grass.
Pros
- Mesotrione is effective on a wide range of weeds
- Visible whitening confirms the product has taken effect
- Small bottle mixes a large volume
- Generic pricing against better known brands
Cons
- Turf tolerance varies, so the label must be checked for your grass
- Bleaching effect looks alarming before the weed dies
Mesotrione works differently from the other actives here. It interferes with pigment production, so treated plants turn white before dying, and that visible bleaching is a useful signal that the application landed.
It is effective across a wide weed spectrum, and generic versions like this deliver the same active at the same concentration as better known brands, which is where the cost difference in this category comes from.
The important step before buying is the turf tolerance list. Mesotrione products are widely used on cool season lawns and their labels are specific about which turf species they suit and at what rates. Read that section against your own grass rather than assuming, because the whitening that makes it easy to confirm on weeds is equally visible on turf that was not meant to receive it.
Bottom line: a capable and economical concentrate for buyers who check the label first rather than after.
- Type: post emergent
- Active ingredient: mesotrione
- Form: liquid concentrate
- Size: 8 ounces
- Application: sprayer, mixed to label rate
- Turf: verify tolerance list before use
Check the tolerant turf species and the rate table on the label against your own lawn before the first application.
Test a small area first if you are uncertain, and wait to see the result before treating the whole lawn.
A small bottle of concentrate goes a long way, so measure carefully rather than mixing generously.
Expect whitening rather than immediate browning, and allow time before judging whether the application worked.
Pros
- Inexpensive and easy to find
- Covers crabgrass alongside broadleaf weeds
- Concentrate form stretches further than ready to use
- Simple to mix for a hand sprayer
Cons
- Less potent than professional grade single active products
- Turf tolerance still needs checking on the label
This is the accessible option, the one most people can buy locally without ordering anything specialised, and for a lawn with a moderate weed problem that counts for a lot.
It covers crabgrass alongside the broadleaf weeds that usually accompany it, so a single mix handles most of what a typical lawn presents in early summer.
It is not as strong as a professional grade single active concentrate, and heavy or mature crabgrass may need something more targeted. As with every product here, the tolerant turf list on the label decides whether it belongs on your grass, and brand familiarity is not a substitute for reading it.
Bottom line: a sensible general purpose treatment for moderate problems, outgunned by dedicated products on a severe infestation.
- Type: post emergent
- Form: liquid concentrate
- Targets: crabgrass and broadleaf lawn weeds
- Application: hand or tank sprayer
- Availability: widely stocked
- Turf: check label tolerance list
Homeowners with a moderate, mixed weed problem who want something available locally at short notice.
Less suitable for a severe crabgrass infestation across a large lawn.
Mix to the labelled rate and avoid spraying on windy days to limit drift onto beds.
Follow the re-entry guidance on the label for people and pets.
Pros
- Quart size suits larger lawns
- Professional line formulation
- Covers grassy and broadleaf weeds
- Economical per treated area when mixed correctly
Cons
- Requires accurate measuring and a proper sprayer
- Label tolerance must be verified for warm season turf
A quart of concentrate is aimed at someone with real lawn area to cover, where buying ready to use bottles stops making sense.
It handles crabgrass alongside broadleaf weeds, which is the practical combination for a large lawn where several problems appear at once rather than one at a time.
Products from professional lines assume a user who measures accurately and owns a tank sprayer. That is the main barrier to entry here rather than the chemistry, and getting the rate wrong on a large area is a more expensive mistake than on a small one. Verify the tolerant turf species for your grass before mixing a full tank.
Bottom line: the efficient choice for larger lawns, provided you are set up to mix and spray properly.
- Type: post emergent
- Form: liquid concentrate
- Size: 1 quart
- Targets: crabgrass and broadleaf weeds
- Application: tank sprayer
- Turf: verify label tolerance before use
Owners of larger lawns who already have a tank sprayer and are comfortable measuring concentrate accurately.
Not the easiest entry point for someone treating a small area for the first time.
Measure into a marked container rather than estimating, and mix only the volume you intend to apply.
Rinse the sprayer thoroughly after use and follow the label re-entry interval for the treated lawn.
How to Choose a Crabgrass Killer For Bermuda Grass
Selective or Not: The Only Question That Matters
A selective herbicide targets certain plants and leaves others standing. A non selective one kills whatever it lands on. Both are sold in the same aisle, both mention grassy weeds on the front, and only one of them belongs anywhere near a lawn you intend to keep.
This matters more with crabgrass than with broadleaf weeds, because crabgrass is a grass. Products that kill grassy weeds are working against a plant closely related to your turf, so the chemistry has to exploit a narrow difference between the two. That is why crabgrass control is a specific category rather than something a general weed killer handles well.
The practical rule is simple. If the label describes clearing an area, a driveway, a fence line or a bed before planting, it is not a lawn product no matter how prominently crabgrass appears on the front. Those have their place, and our guide to non selective herbicides covers when that place is the right one, but a bermuda lawn is not it.
Read the Tolerant Grass List, Not the Front of the Bag
Every selective lawn herbicide carries a list of turf species it can be used on safely, and that list is the single most useful thing on the packaging. Bermuda is a warm season grass with different tolerances from the cool season grasses that dominate northern lawns, and a product formulated with fescue and bluegrass in mind may not be labelled for it.
Mesotrione based products are the clearest example of why this check matters. They are effective and popular, and they are widely used on cool season lawns, but their labels are specific about which turf types they suit. Reading that section before buying takes a minute and prevents a season of damage.
Rate matters as much as species. The same product can be labelled for bermuda at one application rate and cause injury at a higher one, so the tolerant list and the rate table need reading together rather than separately.
Pre Emergent or Post Emergent
These are two different jobs and most people only think about the second one. A pre emergent forms a barrier in the top layer of soil that stops crabgrass seed from establishing after it germinates. It does nothing to plants already growing, so applying it in June to a lawn full of crabgrass achieves close to nothing.
A post emergent kills what is already there. It is the reactive option and it is harder on the lawn, because you are applying a chemical that has to distinguish between two grasses that are both actively growing. It also gets less effective as crabgrass matures, since a plant that has already tillered out into a wide clump is far harder to kill than a young seedling.
The honest answer for most bermuda lawns is both, in sequence across the year. Pre emergent in late winter to catch the germination window, then a selective post emergent for whatever slips through. Relying only on the post emergent means fighting the same battle at higher intensity every summer.
Timing Runs on Soil Temperature, Not the Calendar
Crabgrass germinates when soil temperature at seed depth stays consistently in the mid fifties Fahrenheit, and that happens weeks apart in different regions and years. A pre emergent applied by date rather than by soil temperature is a coin toss.
Applying too late is the common failure, and it is invisible at the time. The barrier goes down after germination has already begun, nothing appears to be wrong, and six weeks later the lawn is full of crabgrass anyway. Applying too early is less wasteful than it sounds but still costs you, since these products break down over time and an early barrier may thin out before the germination window closes.
A cheap soil thermometer removes all the guesswork. Local extension services also publish germination timing for their region, which is more reliable than any general rule about a particular month.
Granule or Liquid Concentrate
Granules spread with a broadcast spreader and suit whole lawn treatment. They are forgiving to apply, they do not drift onto flower beds, and most pre emergents come in this form. The tradeoff is that granules need watering in to move the active ingredient into the soil layer where it works, so a dry week after application wastes the pass.
Liquid concentrates mix in a sprayer and coat the leaf directly, which is what a post emergent needs to do. They allow spot treatment of individual clumps rather than dosing the entire lawn, and they act faster because nothing has to dissolve first. They also demand more care, since spray drift reaches ornamental plants and mixing errors change the rate you actually apply.
For a lawn with scattered clumps, a concentrate and a hand sprayer treats the problem where it is. For a lawn that gets crabgrass every year across the whole area, granules and a spreader are less work and less risk.
Active Ingredients You Will Meet
Four names cover most of this category and knowing them saves reading marketing copy. Quinclorac is the common post emergent for crabgrass in warm season turf and appears in several products here under different brand names. Dithiopyr and prodiamine are pre emergents, with dithiopyr also giving some early post emergent activity on very young crabgrass.
Mesotrione works differently, interfering with pigment production so treated weeds turn white before dying, which is why it is sometimes sold under names referencing that effect. It is effective and its turf tolerance list is worth reading closely rather than assuming.
Generic versions of these actives are common and are chemically the same product at the same concentration. A bottle listing quinclorac at a stated percentage does the same job as a better known brand listing quinclorac at that percentage, which is where a good part of the price spread in this category comes from.
Weed and Feed: Two Jobs in One Bag
Combination products fold fertiliser and herbicide into a single application, and the convenience is real. One pass, one product, one afternoon. For a lawn that needs both at the same moment, they make sense.
The problem is that the two jobs rarely share a schedule. Pre emergent timing is set by soil temperature in late winter, while bermuda wants its nitrogen once it is actively growing and warm, which is later. Applying the combination at the right time for one component means applying it at the wrong time for the other.
Use them when the calendars genuinely overlap or when convenience outweighs precision. Otherwise separate products applied on their own schedules give a better result on both counts.
Rain, Mowing and What Undoes the Application
The two treatments want opposite things from the weather. A granular pre emergent needs water shortly after application to carry it into the soil, so rain in the following days is helpful and a dry spell means running a sprinkler. A liquid post emergent needs to stay on the leaf long enough to be absorbed, and rain within a few hours can wash it off before it works.
Mowing interacts the same way. Cutting the lawn immediately after a post emergent removes the leaf surface that just absorbed the chemical, so leave a couple of days either side. With a pre emergent, avoid anything that disturbs the soil surface, since dethatching or aerating after application breaks the barrier you just laid down.
Coverage area on the label is worth checking against your actual lawn before buying rather than after. Under-dosing to stretch a bottle produces weak control that also selects for tougher weeds, which is the worst of both outcomes.

Why You Should Trust Us
We began by removing every non selective product that appeared in searches for this category, because a killer that takes out crabgrass and bermuda equally is not a lawn product regardless of how it is marketed. What remains is sorted by whether it prevents or treats, which is the distinction that decides whether an application does anything at all.
We then weighted real customer ratings while paying attention to complaints that repeat across many buyers, since reports of lawn damage often trace back to a turf tolerance mismatch or an application rate rather than a faulty product. Where the same formulation is listed under multiple near identical entries, we counted it once.
Final Thoughts
For most bermuda lawns, Scotts Halts Crabgrass and Grassy Weed Preventer is the right first purchase. Preventing germination is easier on the turf and easier on you than killing mature clumps later, and a granular pre emergent applied when soil temperatures reach the germination window does more for a lawn than any summer rescue treatment.
When crabgrass is already established, BASF Drive XLR8 is the strongest post emergent option here for warm season turf, and the generic quinclorac concentrates deliver the same active at a lower cost if you are comfortable measuring carefully. For lawns dealing with broadleaf weeds at the same time, Ortho Weed B Gon Plus Crabgrass Control handles both in one mix.
Whatever you choose, read the tolerant grass list and the rate table together before the first application, and buy a soil thermometer. Those two habits fix more crabgrass problems than switching products ever will. Browse more of our category guides for the rest of the yard.
Frequently Asked Questions
What is the best crabgrass killer for bermuda grass in 2026?
Scotts Halts Crabgrass and Grassy Weed Preventer is our overall pick for 2026 because prevention costs the lawn less than treatment. For crabgrass that is already growing, BASF Drive XLR8 is the stronger choice on warm season turf.
Will crabgrass killer damage bermuda grass?
A selective product labelled for bermuda should not, provided you follow the stated rate. A non selective killer certainly will, and so will a selective product applied above its labelled rate. The tolerant grass list and the rate table on the label are what decide this, not the wording on the front.
When should I apply crabgrass pre emergent?
When soil temperature at seed depth stays consistently in the mid fifties Fahrenheit, which varies by region and by year. A soil thermometer is more reliable than a date, and applying after germination has begun wastes the application entirely.
Do I need to water in a granular crabgrass preventer?
Yes. Granules sit on the surface until water carries the active ingredient into the soil layer where the barrier forms. If no rain is expected in the days after application, run a sprinkler. Our lawn and garden guides cover watering and spreader setup.
Is weed and feed a good idea for bermuda?
Only when the timing for both jobs genuinely overlaps. Pre emergent timing is set by soil temperature in late winter, while bermuda wants nitrogen once it is growing and warm, so a combination product is often applied at the right moment for one component and the wrong one for the other.
