More Details on Our Top Picks
Ortho WeedClear Lawn Weed Killer Ready-to-Use with Comfort Wand, 1 gal.
This ready-to-use weed killer shines for homeowners seeking quick, targeted weed control without dealing with concentrates. Its inclusion of a battery-powered Comfort Wand allows for precise, easy application, making it ideal for spot treating stubborn weeds like crabgrass or dandelions. Compared to the concentrated options, it offers convenience but may require multiple applications for persistent infestations, especially if weeds are mature or heavily established. It’s safe for a variety of lawn grasses, reducing the risk of damage during spot treatments. However, it’s limited to young, actively growing weeds, which means it’s less effective for dormant or mature weeds. For homeowners who prefer a simple, ready-to-apply solution for occasional weed problems, this is a reliable choice, though it isn’t designed for large-scale coverage or heavy infestations.
Pros:- Effective at killing weeds down to the root
- Includes a battery-powered Comfort Wand for easy, precise application
- Safe to use on various lawn grasses
Cons:- Only suitable for young, actively growing weeds
- May require multiple applications for persistent weeds
Best for: Homeowners needing precise, spot treatment for young or isolated weeds in their lawns
Not ideal for: Large lawns with widespread weed issues or mature weeds requiring a broadcast treatment
- Volume:1 gallon
- Application:Spot treatment
- Suitable for:Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass, Zoysiagrass
- Features:Fast-acting, root-killing, includes Comfort Wand
Our verdict“This pick makes the most sense for homeowners seeking quick, targeted weed control without the mess of concentrates.”
Crabgrass Killer (2 Pound Shaker Jar)
This crabgrass killer is designed mainly for post-emergent use on specific grasses like St. Augustine and Bermuda. It absorbs through the leaves to eliminate weeds quickly, making it suitable for active infestations. Compared to the liquid herbicides, it offers the convenience of a shaker jar but demands careful application to avoid damaging desirable grasses. It’s limited to certain turf types and doesn’t specify safety or environmental impact, which might concern eco-conscious users. This product makes sense for homeowners with established crabgrass in compatible lawns who prefer dry, easy-to-store solutions. However, it’s not ideal for lawns with sensitive grass varieties or for preemptive control, meaning timing and application are critical.
Pros:- Effective against crabgrass and weeds
- Absorbed through leaves for targeted weed elimination
- Compact and easy to store
Cons:- Requires careful, precise application to avoid damage
- Limited to specific grass types
- Lacks detailed safety and environmental info
Best for: Gardeners with active crabgrass problems on Bermuda, St. Augustine, Bahia, or Centipede lawns
Not ideal for: Those with sensitive or non-listed turf types, or seeking pre-emergent control
- Weight:2 pounds
- Application:Post-emergent
Our verdict“Ideal for those needing targeted post-emergent crabgrass control on compatible turf types, with careful handling.”
Pro Crabgrass & Grassy Weed Killer – 18.92% Quinclorac – Concentrated Herbicide – 64 Ounces
Compared with the shaker jar, this concentrated liquid herbicide from Sanco Industries provides quicker, more thorough coverage for larger areas. Its high Quinclorac content ensures rapid weed kill and residual control, making it suitable for homeowners managing extensive infestations or commercial landscapes. Unlike the granular option, this liquid offers faster results and better coverage consistency, but it demands careful, accurate application to avoid overuse or damage, especially since it’s a potent chemical. Its effectiveness depends on correct use, and environmental conditions can influence results. This product suits those who need quick, residual weed suppression over large sections of lawn or garden, but it may be overkill for small, casual garden patches.
Pros:- High concentration for effective weed control
- Fast-acting with visible results
- Provides residual weed suppression
Cons:- Effectiveness varies with weed type and conditions
- Requires proper, careful application
- Potentially harmful if misused
Best for: Homeowners or landscapers managing large lawns or commercial landscapes with active weed infestations
Not ideal for: Casual gardeners or those with small, delicate lawns needing gentle control
- Brand:Liquid Harvest
- UPC:768980021339
- Manufacturer:Sanco Industries
- Unit Count:64 Fluid Ounces
- Best Sellers Rank:#25,566 in Patio, Lawn & Garden
Our verdict“This concentrated herbicide is best for those needing quick, residual control over large or heavily infested areas.”
Pro Crabgrass & Grassy Weed Killer – 18.92% Quinclorac Concentrated Herbicide, 32 Ounces
This 32-ounce version of the professional-grade Quinclorac herbicide offers a convenient size for smaller lawns or targeted treatments. It shares the same high concentration and residual control benefits as the 64-ounce bottle but is more manageable for homeowners with limited space or less extensive weed problems. While it provides fast, visible results and long-lasting weed suppression, it requires careful handling and precise application to avoid damage to desirable plants. Compared with the larger size, this option is better suited for smaller or less frequent treatments but might need more applications over time if infestations are severe. It’s a good choice for users who want professional-grade control in a more manageable volume.
Pros:- High concentration for effective control
- Provides residual weed prevention
- Fast-acting with visible results
Cons:- Requires careful, accurate application
- Contains chemicals requiring cautious handling
Best for: Homeowners with small to medium lawns needing quick, residual weed control
Not ideal for: Large-scale properties or those seeking bulk options for extensive infestations
- Concentration:18.92% Quinclorac
- Volume:32 Ounces
- Brand:Liquid Harvest
- UPC:768980021322
- Packs:1
Our verdict“This smaller, professional-grade herbicide is ideal for targeted, quick control in limited areas with careful application.”
Scotts WeedEx Prevent with Halts
This pre-emergent product from Scotts emphasizes preventing crabgrass and other weeds before they sprout. Its large 10.06 lb. bag covers up to 5,000 sq. ft., making it ideal for spring and fall applications. Compared to post-emergent herbicides like the liquid concentrates, it won’t eliminate existing weeds but excels at stopping new ones from germinating, especially on lawns prone to crabgrass infestations. Its weather-resistant formula adds reliability across varying conditions, though it requires reapplication every 8 weeks for continuous control. Not suitable for lawns with Dichondra or Bentgrass, this product targets proactive weed management for those who prefer to avoid chemical treatments once weeds are established. It’s better suited for preventative maintenance than for clearing existing crabgrass patches.
Pros:- Effective at preventing new crabgrass and weed germination
- Weather-resistant performance
- Covers large areas with one bag
Cons:- Does not control existing weeds
- Requires reapplication every 8 weeks
- Not suitable for Dichondra or Bentgrass lawns
Best for: Gardeners wanting a large-area pre-emergent treatment to prevent crabgrass and weed germination
Not ideal for: Lawn owners with existing weed problems or seeking post-emergent control
- Weight:10.06 lbs
- Coverage:5,000 sq. ft
- Application seasons:Spring and Fall
- Grass types:All except Dichondra or Bentgrass
Our verdict“This product makes the most sense for proactive lawn owners aiming to prevent weed germination over large areas, rather than treating existing infestations.”
Roundup for Lawns Crabgrass Destroyer2, 64 fl. oz.
This product stands out for its straightforward, ready-to-use spray that effectively eliminates crabgrass at the root, making it ideal for homeowners seeking quick, targeted results. Unlike more complex concentrates like BASF Drive XLR8, this formula requires no mixing, reducing application time and mess. However, it performs best during active weed growth and within a specific temperature range of 45°F to 90°F, limiting its flexibility in cooler climates. While not offering residual control, its ease of use makes it perfect for spot treatments. Compared to larger, more industrial options, this is better suited for small to medium lawns needing quick results without chemical handling. The main tradeoff is its dependency on active growth stages, so timing is critical. Overall, this is best for casual users prioritizing simplicity and immediate results.Pros:- Effective at killing crabgrass at the root
- Ready-to-use trigger spray simplifies application
- Suitable for multiple common grass types
Cons:- Requires active weed growth for best results
- Limited temperature range (45°F-90°F) restricts use in cooler weather
Best for: Homeowners with small to medium lawns who want quick, easy, spot crabgrass control
Not ideal for: Large commercial properties or lawns with cool climates where weed activity is limited
- Volume:64 fl. oz.
- Application:Ready-to-use trigger sprayer
- Suitable for:Kentucky bluegrass, fine fescue, perennial ryegrass, tall fescue
- Temperature Range:45°F to 90°F
Our verdict“Ideal for homeowners seeking fast, hassle-free spot treatment during active weed growth seasons.”
BASF Drive XLR8 Crabgrass Killer for Lawn & Turf, 64 Ounce
This water-based concentrate offers up to 30 days of residual weed control, making it ideal for those wanting a longer-lasting solution, especially in professional or extensive turf settings. Compared with Roundup’s quick-acting spray, Drive XLR8 requires careful handling and proper PPE, reflecting its more industrial-grade formulation. Its broad-spectrum weed control also includes broadleaf weeds, providing a comprehensive approach. The tradeoff lies in its application complexity and regional restrictions—some areas restrict spot application and require multiple treatments for persistent weeds. It’s well-suited for larger lawns or turfgrass environments like golf courses, where residual control is a priority. However, for casual DIY users, the need for safety precautions and handling might be a barrier. This product suits users wanting durable, long-term control over crabgrass and weeds, with a focus on professional-grade performance.Pros:- Up to 30 days residual weed control
- Effective against crabgrass and broadleaf weeds
- Versatile for warm and cool-season turf
Cons:- Requires careful handling and PPE due to chemical potency
- Limited to spot application in some regions
Best for: Lawn care professionals or homeowners with large, weed-prone turf needing long-lasting control
Not ideal for: Casual users or those with small lawns seeking simple, quick treatments without safety concerns
- Active Ingredient:Quinclorac
- Volume:64 Ounce
- Formulation:Water-Based
- Residual Control:Up to 30 days
- Application:Spot application
- Suitable for:Warm-season and cool-season turf
Our verdict“Designed for users prioritizing extended control in large or professional turf environments, with safety precautions in mind.”
Ortho WeedClear Lawn Weed Killer Concentrate, 32 fl. oz.
This concentrate excels at quickly killing weeds like crabgrass, dandelions, and clover down to the root, making it a good choice for fast results on smaller lawns. Unlike BASF Drive XLR8, which offers residual control, Ortho WeedClear focuses on immediate eradication, which suits homeowners needing quick cleanup. Its effectiveness depends on proper dilution and application, making precision important. While it covers up to 5,000 sq. ft., larger lawns may require multiple applications, adding to cost and effort. It is compatible with various northern grasses but contains chemicals that demand careful handling. This product works best for users wanting rapid results without long-term residual expectations, but it’s less suited for those seeking extended weed suppression.Pros:- Kills weeds down to the root quickly
- Effective on multiple weed types including crabgrass
- Safe for many lawn grasses when used properly
Cons:- Requires careful dilution and application
- Limited coverage for larger lawns
Best for: Homeowners needing quick, effective weed control in small to medium lawns
Not ideal for: Large lawns or users seeking long-lasting weed prevention
- Volume:32 fl. oz.
- Coverage:up to 5,000 sq. ft.
Our verdict“Best suited for homeowners who want fast, targeted weed removal with minimal fuss.”
Drive Crabgrass Killer Lawn & Turf, Post Emergent Weed Control, Quinclorac, 64 Ounce
This product combines effective post-emergent crabgrass control with a 30-day residual, making it suitable for maintaining turf health over time. It’s comparable to BASF Drive XLR8 but marketed under a different brand, with the added inclusion of protective gloves for safer handling. Its effectiveness depends on correct application in active weed stages, and the limited information on instructions can be a drawback. Customer reviews are mixed, suggesting some users experience variability in results. It’s best for turf managers who prefer a ready-to-apply liquid and want a product that balances immediate knockout with ongoing control. For casual DIYers, the lack of detailed instructions and mixed reviews might be a concern.Pros:- Effective post-emergent weed control
- Provides a 30-day residual effect
- Includes protective gloves for safer application
Cons:- Mixed customer reviews indicate variable results
- Limited application instructions available
Best for: Lawn care professionals or dedicated homeowners seeking reliable post-emergent weed control with residual effects
Not ideal for: Beginners or those needing detailed application guidance and consistent reviews
- Brand:USA Supply
- Size:64 Ounces
- Active Ingredient:Quinclorac
- Residual:30 days
- Application:Lawn & Turf
Our verdict“Suitable for users who want a balanced, post-emergent crabgrass solution with residual control, with awareness of potential variability.”
BioAdvanced All-In-One Lawn Weed and Crabgrass Killer I, Ready-to-Use, 24 oz
This ready-to-use formula targets over 200 weeds, including crabgrass, with a penetrating action that reaches weeds down to the root, making it a strong choice for diverse weed problems. Compared with the more specialized products like Roundup or BASF Drive, this offers broader weed coverage in a single application, which simplifies weed management for homeowners with multiple weed types. Its quick rainproof feature within an hour adds convenience, though the smaller 24 oz size limits coverage and may require repeated applications for larger lawns. It’s ideal for users who prefer a single, versatile product over multiple treatments, but the limited size and specificity to certain lawn types can be drawbacks.Pros:- Controls over 200 weeds including crabgrass
- Rainproof in just one hour
- Easy to apply with included sprayer
Cons:- Limited to 24 oz, requiring multiple applications for large lawns
- Some lawn types may not be suitable
Best for: Homeowners needing an all-in-one, multi-weed solution for small to medium lawns
Not ideal for: Larger lawns or those seeking long residual control or targeting specific weeds
- Volume:24 oz
- Application:Ready-to-use spray
- Rainproof Time:1 hour
- Suitable for:Fescue, Kentucky Bluegrass
Our verdict“Ideal for users looking for a broad-spectrum, easy-to-use weed killer for small lawns or multiple weed problems.”
Preen Lawn Crabgrass Control 15 lb. Bag, Covers 5,000 sq. ft.
This granular crabgrass control stands out for its ability to prevent weeds all season long, making it ideal for homeowners who want to stop crabgrass before it starts. Compared with BioAdvanced’s spray, Preen offers a larger coverage area at a lower cost, but it requires precise timing within the first 4 weeks of crabgrass emergence and careful application. It’s best suited for those who prefer a straightforward, pre-emergent approach without dealing with sprays or concentrates. However, its focus on prevention means it won’t help with existing crabgrass or weeds, so it’s less useful if the problem is already visible. The granular form can be tricky to spread evenly, and it’s limited to weed prevention rather than eradication. If you want to stop crabgrass early and have a large lawn, this makes the most sense, but if you already have mature weeds, a different treatment might be better.
Pros:- Prevents crabgrass and over 40 weeds all season
- Suitable for various grass types, including cool and warm-season grasses
- Provides coverage for up to 5,000 sq. ft at a reasonable price
Cons:- Must be applied within 4 weeks of crabgrass emergence for effectiveness
- Granular form can be difficult to apply evenly without proper equipment
- Limited to prevention—won’t kill existing weeds or crabgrass
Best for: Homeowners seeking a reliable, large-area preventative solution for crabgrass and common weeds early in the season.
Not ideal for: Gardeners with mature crabgrass patches needing immediate eradication or those preferring spray applications for spot treatment.
- Weight:15 lbs
- Coverage:5,000 sq. ft
- Application:Prevents crabgrass and weeds all season
- Timing:Apply up to 4 weeks after crabgrass emerges
Our verdict“This product is ideal for proactive homeowners wanting to prevent crabgrass before it appears, especially on large lawns.”
BioAdvanced All-in-One Lawn Weed & Crabgrass Killer Concentrate – 32 oz
Compared with Preen’s preventative approach, BioAdvanced’s concentrate excels at targeting mature crabgrass and weeds like dandelion and clover, providing quick, rainproof kills within an hour. It’s especially suitable for homeowners who already see crabgrass and want fast results, offering up to 3 months of control for over 90 weeds. While it’s more effective for existing weeds than Preen, it requires careful mixing and handling the concentrate, which might be intimidating for beginners. The spray’s rapid rainproof time and broad weed spectrum make it a versatile choice, but multiple applications may be needed for persistent weeds. It’s less ideal for large lawns where preventative coverage is preferred, and more suited for spot treatments or tackling stubborn patches. Overall, this makes the most sense for those who need an effective, quick-acting solution for existing crabgrass and weeds, rather than prevention.
Pros:- Effective against a wide range of weeds including crabgrass and dandelions
- Rainproof in just 1 hour, providing quick results
- Safe for common grass types when used as directed
Cons:- Multiple applications may be necessary for persistent weeds
- Concentrate formula requires careful mixing and handling
- Less suitable for large lawns due to spot-treatment focus
Best for: Homeowners seeking a fast-acting, broad-spectrum weed killer for mature crabgrass and weeds on small to medium lawns.
Not ideal for: Those who prefer a preventative, large-area treatment or are uncomfortable with mixing concentrates for larger lawns.
- Volume:32 oz
- Application:Concentrate spray
- Rainproof Time:1 hour
- Coverage Duration:Up to 3 months
Our verdict“This concentrate is best for homeowners who need a fast, effective solution to kill existing crabgrass and weeds with minimal wait time.”
How We Picked
These products were selected based on their effectiveness at controlling crabgrass, ease of application, and overall value. We prioritized products with proven active ingredients like quinclorac and other selective herbicides known for targeting crabgrass specifically. Safety considerations, such as turf tolerance and ease of use, also played a role, along with coverage area and user convenience. Our ranking reflects a balance between cost, performance, and suitability for different homeowner needs, from DIYers to professionals. Products that excelled in multiple categories earned higher positions, while those with notable tradeoffs were positioned accordingly.Factors to Consider When Choosing Crabgrass Killer
Choosing the right crabgrass killer involves more than just picking the strongest formula. You need to consider factors like application method, timing, lawn size, safety, and budget. Understanding these elements helps you avoid common missteps and select a product that delivers effective control without damaging your lawn or wasting money.Application Method and Ease of Use
Some products come ready-to-use, making them ideal for quick, straightforward applications, especially for homeowners unfamiliar with mixing chemicals. Others require dilution and precise measurement, which can be more cost-effective but also more complex. Consider your comfort level and whether you prefer a spray wand, shaker jar, or concentrated formula. Easy-to-apply products reduce the risk of misuse and ensure even coverage.Timing and Lawn Conditions
Applying crabgrass killer at the right stage—before germination or early growth—maximizes effectiveness. Products vary in how quickly they act, with some providing visible results within days and others taking longer. Also, consider current weather conditions; rain can wash away certain herbicides, while hot, dry weather may require more frequent treatments. Proper timing ensures your investment yields the best control.Coverage Area and Cost
Larger bags or bottles may offer better value per square foot, but they can be cumbersome for small lawns. Conversely, smaller containers are easier to handle but might be more expensive per unit area. Think about your lawn size and whether you prefer a one-time treatment or ongoing control. Matching coverage to your lawn’s needs helps optimize your spending.Safety and Turf Tolerance
Some crabgrass killers are highly potent and may pose risks to desirable turf or surrounding plants if misused. Always check product labels for turf tolerance ratings and safety precautions. In sensitive lawns, opting for selective herbicides can prevent damage while effectively controlling crabgrass. Safety considerations are especially important if you have children or pets around.Budget and Long-Term Value
While premium products often deliver faster or more reliable results, budget options can still be effective if used correctly and at the right time. Consider your lawn size and how often you’ll need treatments. Investing in a higher-quality product might reduce the need for repeated applications, saving money and time in the long run. Balance your immediate needs with long-term lawn health.Frequently Asked Questions
Can I use crabgrass killer on a newly seeded lawn?
Generally, most crabgrass killers are not suitable for newly seeded lawns because they can harm young grass seedlings. It’s best to wait until your grass has established sufficiently before applying any herbicide. Read the product label carefully for any restrictions related to new seedings, and consider spot treatments if only certain areas are infested. Patience during this initial stage helps ensure your new lawn’s health and long-term success.
How soon can I mow after applying crabgrass killer?
Most herbicides recommend waiting at least 24 to 48 hours after application before mowing. This allows the product to be absorbed properly and reduces the risk of spray residue damaging your mower blades or spreading to unintended areas. Always check the specific instructions on your product for the safest timing, as some formulations may have longer or shorter waiting periods.
Is crabgrass killer safe for pets and children?
Safety depends on the specific product and its ingredients. Many selective herbicides are formulated to minimize risks to pets and children when used as directed, but it’s always best to keep them off the lawn during and immediately after treatment. Washing hands after application and avoiding contact with treated areas can further reduce risks. For peace of mind, look for products labeled as pet- and child-safe or consult with a lawn care professional.
Should I apply crabgrass killer before or after weed germination?
The most effective time to apply crabgrass killer is before the weed germinates or during early growth stages. Pre-emergent herbicides prevent crabgrass seeds from sprouting, while post-emergent formulations target existing plants. Applying too late, after the weeds are well-established, lessens the effectiveness and may require repeat treatments. Timing correctly enhances results and reduces the need for multiple applications.
Can I use crabgrass killer on other weeds or grass types?
Many crabgrass killers are selective and target specific grassy weeds without harming the desired turf. However, some broad-spectrum herbicides can damage or kill all types of grass if misapplied. Always check the label for compatibility with your lawn type and whether other weeds are also controlled. Using the right product for your specific weed problem prevents unnecessary damage and ensures better lawn health.
Conclusion
For homeowners seeking a quick and effective solution, the Ortho WeedClear Lawn Weed Killer Ready-to-Use offers ease of application with reliable results. If you want to cover large areas on a budget, the Preen Lawn Crabgrass Control provides excellent value. For those dealing with stubborn patches or preferring concentrated formulas, the BASF Drive XLR8 delivers fast, potent control, though with a need for careful handling. Beginners or casual users should prioritize ready-to-use options, while professionals or those with large lawns might lean toward concentrated or bulk products. Choose based on your lawn size, safety preferences, and how quickly you want results to get the best fit for your needs.
