Drive XLR8 Crabgrass Killer for Lawn & Turf

The BASF Drive XLR8 formulation targets a broad spectrum of grasses and broadleaf weeds with a post-emergent action. Its active ingredient, quinclorac, helps rapid uptake and quick visible results. A notable feature is its extended residual control, offering up to 30 days of protection after application, which reduces the frequency of re-applications in a busy lawn care schedule. The product is designed to be rainfast within an hour, minimizing wash-off risk during light showers. For centipede lawns, this product provides post-emergent control of common offenders like crabgrass and several broadleaf species while attempting to minimize turf stress when applied according to label directions.
Key considerations for centipede lawns: follow the label for concentration, avoid application during extreme heat, and observe any restrictions on mowing or irrigation after treatment. This product is most effective when weeds are actively growing and when air temperatures align with label guidelines.
Mesotrione Weed Killer Concentrate (8 oz) – Compare to Tenacity

Mesotrione Weed Killer Concentrate for New & Existing Lawns
The Mesotrione Weed Killer Concentrate is a versatile post- and pre-emergent option designed for lawns, including centipede. It targets a wide array of Broadleaf and grassy weeds such as crabgrass, dandelion, and clover, offering both post-emergent control and pre-emergent protection against future germination. The product is easy to apply with standard spray equipment, and its broad label coverage helps manage tough weed populations. For centipede lawns, it is important to ensure compatibility with cool- and warm-season grasses and to follow the recommended dilution rates to prevent turf injury.
Usage tip: apply when targeted weeds are actively growing and avoid applying during drought stress or extreme heat to minimize potential turf stress. Ensure thorough coverage for maximum effectiveness.
Scotts WeedEx Prevent with Halts

Scotts WeedEx Prevent with Halts
Scotts WeedEx Prevent with Halts is a pre-emergent product designed to prevent crabgrass and other season-long weeds. While not a post-emergent solution, it is valuable for centipede lawns that require proactive weed control in early spring. It helps establish a barrier before seeds germinate, reducing weed pressure as the season progresses. For centipede grass, combining pre-emergent prevention with selective post-emergent treatments can provide a balanced weed management strategy, especially in regions with heavy crabgrass pressure.
Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food
The Scotts Turf Builder Halts Crabgrass Preventer is another pre-emergent option that combines weed prevention with lawn nutrition. It helps keep crabgrass at bay and promotes a healthy lawn with fertilizer. For centipede lawns, applying this product in early spring can help reduce weed emergence before germination. It’s important to follow label directions and avoid applying during periods of heat stress or when mowing requirements could be disrupted by application timing.
Bonide (BND60400) Crabgrass and Weed Preventer

Bonide Crabgrass and Weed Preventer
Bonide Crabgrass and Weed Preventer is a ready-to-use, granular pre-emergent designed to protect lawns and ornamental beds from crabgrass and a broad spectrum of weeds for up to four months. It covers up to 5,000 square feet, making it suitable for medium-sized centipede lawns. For best results, apply in early spring before weeds germinate and re-apply according to label timing to maintain protection through the growing season. This product is especially convenient for homeowners who prefer a straightforward application method.
Buying Guide: Key Considerations for Centipede Grass and Post-Emergent Weeds
When selecting a post-emergent or preventive weed control product for centipede grass, consider weed spectrum, application timing, and turf safety. Centipede grass is sensitive to some herbicides, so always read the label to confirm compatibility with warm-season grasses. The following factors help you make informed decisions:
- Weed spectrum: Identify whether you primarily face crabgrass, foxtail, dandelion, clover, or other broadleaf weeds. Choose products with proven activity against those species.
- Post-emergent vs. pre-emergent: Post-emergent products treat existing weeds, while pre-emergents prevent future germination. A combination approach often yields the best results for centipede lawns, especially in transitional seasons.
- Active ingredients: Quinclorac-based products (like Drive XLR8) are common post-emergents for grassy weeds; mesotrione offers broad-spectrum control with both post- and pre-emergent properties. Check for turf safety on centipede grass.
- Residual activity: Short-term vs. long-term residuals affect how often you re-treat. Consider your mowing schedule, irrigation, and recent weather.
- Application timing: Spring and early summer are typical windows for post-emergent activity in warm-season grasses. Avoid extreme heat and drought conditions at application time.
- Safety and containment: Use proper protective gear and keep pets and children away during and after application as directed by the label.
- Lawn size and coverage: Ensure the product dosage and bag size align with your lawn square footage to achieve even coverage without over-application.
- Mowing and irrigation: Some products require a window before mowing or irrigation. Plan your lawn care schedule to maintain weed control effectiveness.
For centipede lawns, a practical approach is to combine a post-emergent herbicide such as BASF Drive XLR8 for active weeds with a pre-emergent program from Scotts WeedEx Prevent or Scotts Turf Builder Halts to reduce future weed pressure. Always follow the product label for adaptation to local climate, soil type, and lawn condition. When in doubt, test a small area first to ensure there is no phytotoxic reaction on centipede grass.
