Understanding Centipede Grass and Its Weed Control Needs
Before diving into the product reviews, it’s worth understanding why centipede grass requires special consideration when it comes to herbicides. Known scientifically as Eremochloa ophiuroides, centipede grass is a warm-season turfgrass that thrives in USDA zones 7-10. It’s popular for its drought tolerance, low fertilizer requirements, and ability to form a dense carpet that naturally suppresses some weeds. However, its slow growth rate and sensitivity to certain chemicals make it vulnerable to damage from improper herbicide use.
Common weeds in centipede lawns include crabgrass, goosegrass, dollarweed, chickweed, clover, and sedges like nutsedge. These invaders can detract from the lawn’s uniformity and compete for nutrients, water, and sunlight. Herbicides fall into two main categories: pre-emergent (preventing weed seeds from germinating) and post-emergent (killing existing weeds). Centipede grass is particularly sensitive to herbicides containing 2,4-D, MSMA, or high nitrogen levels, so selecting a product labeled as safe for this grass is essential.
With this in mind, let’s explore our top five picks and see how they stack up for centipede grass care in 2025.
Product Reviews
1. The Andersons Barricade Professional-Grade Granular Pre-Emergent Weed Control
- Specifications: 18 lb bag, covers up to 5,800 sq ft, active ingredient: Prodiamine (0.58%)
- Price: Approximately $50-$60 (varies by retailer)
- Type: Pre-emergent granular herbicide
Overview
The Andersons Barricade is a professional-grade pre-emergent herbicide designed to stop weeds before they start. Its active ingredient, prodiamine, is widely regarded as safe and effective for centipede grass when applied according to label instructions. This granular product is ideal for homeowners looking to prevent annual grassy weeds like crabgrass and broadleaf weeds such as chickweed from taking root in their lawns.
Effectiveness
Barricade excels at creating a chemical barrier in the soil that inhibits weed seed germination. It targets over 35 common weed species, including crabgrass, foxtail, and annual bluegrass—frequent offenders in centipede lawns. When applied in late winter or early spring (around March or April in most southern climates), it provides 60-90 days of protection, carrying you through the early growing season. For best results, a second application can be made in late summer to tackle fall-germinating weeds like henbit.
Testing this product on a centipede lawn showed a noticeable reduction in weed emergence compared to untreated areas. By mid-summer, the treated lawn remained largely weed-free, while adjacent untreated patches sprouted crabgrass and spurge. Its staying power makes it a top choice for proactive weed management.
Safety for Centipede Grass
Prodiamine is a dinitroaniline herbicide that’s well-tolerated by centipede grass when used at recommended rates. Over-application, however, can stress the grass, particularly during periods of heat or drought. The label advises against use on newly seeded lawns, so it’s best suited for established turf. When applied correctly, no yellowing or thinning was observed in testing, affirming its safety profile.
Ease of Use
The granular formulation requires a broadcast or drop spreader for even application, which might be a slight hurdle for those without equipment. After spreading, it needs to be watered in within a few days to activate the barrier—about 0.5 inches of irrigation or rainfall does the trick. The 18 lb bag covers up to 5,800 sq ft, making it suitable for medium-sized lawns, though larger properties may require multiple bags.
Value for Money
At $50-$60, Barricade offers excellent value for its coverage and longevity. A single application can save hours of manual weeding or costly post-emergent treatments later. It’s a cost-effective choice for those committed to a weed prevention strategy.
Pros
- Long-lasting pre-emergent control (60-90 days)
- Safe for established centipede grass
- Covers a large area (5,800 sq ft)
- Professional-grade efficacy
Cons
- Requires a spreader and watering-in
- Not suitable for newly seeded lawns
- Limited to pre-emergent action only
Verdict
The Andersons Barricade is the best pre-emergent herbicide for centipede grass in this roundup. Its reliability, safety, and coverage make it a must-have for homeowners aiming to stay ahead of weeds.
2. PetraMax Blue Herbicide Lawn Dye
- Specifications: 8 oz concentrate, mixes with herbicides or fertilizers, 3X strength
- Price: Around $20-$25
- Type: Spray indicator dye
Overview
PetraMax Blue Herbicide Lawn Dye isn’t a herbicide itself but a powerful companion product that enhances the precision of herbicide applications. This super-concentrated blue dye mixes with liquid herbicides or fertilizers, making it easier to see where you’ve sprayed and avoid overlaps or missed spots. For centipede grass, where over-application can lead to damage, this tool is invaluable.
Effectiveness
While it doesn’t kill weeds directly, PetraMax boosts the effectiveness of any herbicide by ensuring even coverage. During testing with a post-emergent herbicide (like Torocity, reviewed below), the dye revealed gaps in application that might have been missed, allowing for a more thorough treatment of weeds like dollarweed and clover. It fades within 24-48 hours under sunlight, leaving no permanent mark on the lawn.
Safety for Centipede Grass
The dye is non-toxic and safe for all turfgrasses, including centipede. It doesn’t alter the herbicide’s chemistry or add any harmful substances, so there’s no risk of injury to the grass when used as directed. In practice, no adverse effects were noted on centipede lawns during application.
Ease of Use
Mixing is straightforward: add 1-2 oz of dye per gallon of spray solution (adjust based on desired intensity). It works with backpack sprayers, handheld sprayers, or tank systems, making it versatile for lawns of all sizes. The 8 oz bottle is enough for multiple applications, depending on your lawn’s square footage and spraying frequency.
Value for Money
At $20-$25, PetraMax is an affordable add-on that maximizes the efficiency of your herbicide investment. It’s particularly cost-effective for those treating large areas or using expensive herbicides, as it prevents waste from over-spraying.
Pros
- Enhances application accuracy
- Safe and non-toxic for centipede grass
- Economical concentrate (3X strength)
- Fades naturally within days
Cons
- Not a standalone weed control solution
- Requires mixing with another product
Verdict
PetraMax Blue Herbicide Lawn Dye is the best accessory for herbicide application on centipede grass. It’s a game-changer for precision and efficiency, earning a spot in any lawn care toolkit.
3. Torocity Herbicide (8oz) by Atticus
- Specifications: 8 oz concentrate, active ingredient: Mesotrione (40%), pre- and post-emergent
- Price: Approximately $50-$60
- Type: Selective liquid herbicide
Overview
Torocity by Atticus is a mesotrione-based herbicide often compared to the popular Tenacity. It offers both pre-emergent and post-emergent control, making it a versatile option for centipede grass lawns plagued by weeds like crabgrass, clover, and nutsedge. Its systemic action targets weeds without harming most turfgrasses, including centipede.
Effectiveness
Torocity shines in its dual-action capability. As a pre-emergent, it prevents weed seeds from sprouting, while as a post-emergent, it kills existing weeds by inhibiting photosynthesis. In testing, it effectively whitened and killed broadleaf weeds like chickweed and dandelions within 7-14 days, with grassy weeds like crabgrass showing results in 2-3 weeks. Its residual effect lasts 45-60 days, offering extended protection.
Safety for Centipede Grass
Mesotrione is known for its safety on centipede grass when applied at recommended rates (typically 0.5-1 oz per gallon of water per 1,000 sq ft). Overuse can cause temporary whitening of the grass, but it recovers quickly. No permanent damage was observed in testing, making it a reliable choice for selective weed control.
Ease of Use
This concentrate requires mixing with water and a surfactant (for better adhesion) before spraying. A backpack or pump sprayer is ideal, and pairing it with PetraMax dye (above) enhances accuracy. The 8 oz bottle treats up to 16,000 sq ft, depending on the application rate, which is generous for small to medium lawns.
Value for Money
Priced at $50-$60, Torocity is a cost-effective alternative to Tenacity, offering similar performance at a lower price point. Its versatility justifies the investment for those dealing with both emerging and established weeds.
Pros
- Pre- and post-emergent control
- Safe for centipede grass
- Targets a wide range of weeds
- Long-lasting residual effect
Cons
- Requires careful mixing and a surfactant
- Slower results on some weeds (2-3 weeks)
Verdict
Torocity is the best all-around herbicide for centipede grass, blending pre- and post-emergent action into one powerful package. It’s perfect for tackling mixed weed problems.
4. Pet’s Pal Natural Weed Killer
- Specifications: 1 gallon ready-to-use, natural herbicidal soap, glyphosate-free
- Price: Around $30-$35
- Type: Non-selective natural herbicide
Overview
Pet’s Pal Natural Weed Killer is a pet- and kid-safe alternative to synthetic herbicides, using herbicidal soaps to desiccate weeds on contact. It’s marketed as an environmentally friendly option, free of glyphosate, and ready-to-use straight from the bottle.
Effectiveness
This product works best on young, tender weeds like chickweed or annual grasses, drying them out within hours of application. In testing, it killed small clover patches and spurge in a centipede lawn within a day. However, it struggles with mature weeds or deep-rooted species like nutsedge, requiring multiple applications for partial control. As a non-selective herbicide, it kills any plant it touches, so spot treatment is critical.
Safety for Centipede Grass
While safe for pets and humans, Pet’s Pal is not selective—it will damage centipede grass if sprayed directly. Careful application with a shield or wand is necessary to avoid collateral damage. In practice, minor overspray caused temporary browning, but the grass recovered within a week.
Ease of Use
The ready-to-use formula is a major plus—no mixing required. It comes with a built-in sprayer, ideal for spot treatments on small lawns or garden beds. The 1-gallon jug covers roughly 200-300 sq ft, depending on weed density.
Value for Money
At $30-$35 per gallon, it’s pricier per square foot than concentrates like Torocity, and its limited efficacy on tough weeds reduces its overall value. It’s best for eco-conscious users with minimal weed issues.
Pros
- Pet- and kid-safe natural formula
- No mixing; ready-to-use
- Fast action on young weeds
Cons
- Non-selective; harms centipede grass if misapplied
- Weak against mature or woody weeds
- Lower coverage per dollar
Verdict
Pet’s Pal is the best natural herbicide for centipede grass in small, controlled applications. It’s a niche pick for eco-friendly spot treatments but not a comprehensive solution.
5. Fertilome Centipede Weed & Feed 15-0-15
- Specifications: 16 lb granular, 15-0-15 NPK, covers 5,000 sq ft, includes herbicide
- Price: Approximately $25-$30
- Type: Weed and feed (post-emergent herbicide + fertilizer)
Overview
Fertilome Centipede Weed & Feed combines a 15-0-15 fertilizer with a broadleaf herbicide, targeting weeds like dandelions and dollarweed while nourishing centipede grass. It’s formulated specifically for this turf type, aiming to simplify lawn care into one step.
Effectiveness
The herbicide component (likely a 2,4-D blend, though not specified) effectively controls broadleaf weeds, with visible wilting in 3-5 days during testing. It’s less effective against grassy weeds like crabgrass, requiring a separate pre-emergent like Barricade for full coverage. The fertilizer promotes greening and growth, though its high nitrogen content (15%) demands caution to avoid overfeeding.
Safety for Centipede Grass
Centipede grass tolerates this product well when applied during active growth (spring or early summer) and not during dormancy or heat stress. Overuse or application in hot weather (>90°F) risked yellowing in tests, underscoring the need to follow label timing.
Ease of Use
Applied with a spreader, it’s simple to use but requires moist grass for the granules to stick to weed leaves. Watering-in isn’t needed unless rain is absent for 24 hours. The 16 lb bag covers 5,000 sq ft, fitting most home lawns.
Value for Money
At $25-$30, it’s a budget-friendly dual-purpose product, though its weed control is narrower than standalone herbicides. It’s a solid value for broadleaf-focused maintenance.
Pros
- Combines weed control and fertilizer
- Affordable and widely available
- Easy granular application
Cons
- Limited to broadleaf weeds
- High nitrogen may stress centipede if over-applied
- Timing-sensitive
Verdict
Fertilome Weed & Feed is the best weed and feed option for centipede grass, ideal for broadleaf control and basic nutrition on a budget.
