Goosegrass is one of the toughest grassy weeds to control in warm-season lawns, known for its flattened stems, finger-like seed heads, and uncanny resistance to many standard herbicides. It thrives in compacted soil, high heat, and heavy foot traffic, which means the usual broadleaf weed sprays often leave it standing.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend weeks comparing chemical formulations, reading aggregated owner reports, and studying horticultural data to separate the formulas that actually stop goosegrass from the ones that just waste application time.
This guide breaks down the top-performing chemistries so you can finally eliminate this weed from your turf. After evaluating dozens of products based on active ingredients, rainfast timing, and lawn safety, we’ve ranked the best goose grass herbicide options available right now.
How To Choose The Best Goose Grass Herbicide
Goosegrass (Eleusine indica) is not your average lawn weed. Its deep, fibrous root system and tolerance to heat mean most off-the-shelf weed-and-feed products are useless. Selecting the right herbicide depends on three factors: your lawn’s grass type, the weed’s growth stage, and the active chemistry in the bottle.
Selective vs. Non-Selective Formulas
If goosegrass has invaded your Bermuda, Zoysia, or Centipede lawn, you need a selective post-emergent herbicide like those containing Sulfentrazone or MSMA (where legal). These kill goosegrass without killing your turf. Non-selective options like Glyphosate or Diquat will burn everything green, so reserve those for patios, driveways, or bare soil areas only.
Pre-Emergent vs. Post-Emergent Timing
Goosegrass seeds germinate in late spring when soil temperatures hit 60-65°F. A pre-emergent barrier (containing Prodiamine or Dithiopyr) applied before that window stops seeds from sprouting. If you missed that window and the weed is already visible, you need a post-emergent killer that targets actively growing goosegrass. Most homeowners fight goosegrass in post-emergent mode because the weed reveals itself only after it matures.
Active Ingredient Matching
Not all “grass killers” work on goosegrass. The most reliable chemistries for this specific weed include Sulfentrazone (found in Bonide Sedge Ender), which attacks roots and shoots simultaneously. Ferti-lome Over The Top Grass Killer uses a different selective agent that stops growth within two days. Ortho Grass B Gon targets grassy weeds in garden beds where you don’t want collateral damage to ornamentals. Match the active ingredient to your specific lawn condition for clean results.

In‑Depth Reviews
1. Bonide Sedge Ender
Bonide Sedge Ender is the most versatile option for homeowners fighting goosegrass in their lawn without destroying the turf. Its active ingredient, Sulfentrazone, targets goosegrass roots and shoots simultaneously — a critical advantage because goosegrass often resprouts from deep roots if only the foliage is hit. The product works on both warm-season grasses like Bermuda and cool-season varieties like fescue, making it a safe choice for most American lawns.
The 16-ounce ready-to-spray bottle connects directly to your garden hose, treating up to 8,700 square feet per container. That coverage range makes it extremely economical for a mid-sized yard, and the rainproof formula locks into leaf tissue within hours, meaning you do not have to time applications around an unpredictable forecast. Many users report visible wilting of goosegrass within 24 to 48 hours of application.
One distinction that matters: this product kills yellow nutsedge, crabgrass, and goosegrass but spares your lawn grass. That selectivity is the reason it earns the top spot — it solves the specific goosegrass problem without forcing you to reseed dead patches afterward. Applying it when goosegrass is young and actively growing delivers the cleanest kill.
What works
- Selective formula kills goosegrass without harming lawn grasses
- Rainproof in hours, avoiding washout frustration
- Massive 8,700 sq ft coverage per 16-ounce bottle
What doesn’t
- Not effective on mature, seed-head-stage goosegrass
- Requires a hose-end sprayer attachment which may drip if not tightened
2. RM18 Fast-Acting Weed & Grass Killer
RM18 Fast-Acting Weed & Grass Killer is a non-selective herbicide designed for areas where total vegetation removal is the goal. If you are dealing with goosegrass growing through cracks in your driveway, along fence lines, or in a patch of bare dirt you plan to reseed, this 32-ounce spray offers quick knockdown without the high price tag of premium specialty products. The formula is ready to use out of the bottle, so there is no measuring or mixing.
Coverage tops out around 3,000 square feet per bottle, which makes it a better fit for spot treatments and small-to-medium hardscapes rather than full-lawn applications. The non-selective chemistry means it burns any green tissue it contacts, so you cannot spray near desirable turf or ornamentals without careful masking. Users commonly see goosegrass begin yellowing within hours and browning completely over the following two days.
This product fits best as a tactical tool for isolated goosegrass clumps in non-lawn zones. Pair it with a selective herbicide for your lawn turf, and use RM18 only where total kill is acceptable. The low per-bottle investment makes it painless to keep a spare in the garage for quick spot work after weeding.
What works
- Fast visual results — users report browning in under 48 hours
- Ready-to-use trigger sprayer simplifies application
- Low entry cost for non-selective spot treatment
What doesn’t
- Non-selective; kills any grass or plant it touches
- Limited coverage area at 3,000 sq ft per bottle
3. Ortho Grass B Gon Garden Grass Killer
Ortho Grass B Gon is a selective grass killer formulated specifically for use in garden beds and around ornamental plants. If your goosegrass infestation is mixed in with flowers, shrubs, or decorative landscaping, this product allows you to target the unwanted grass without harming your ornamentals. Each package contains two 24-ounce ready-to-use spray bottles, giving you 48 ounces total — enough for repeated treatments across a medium garden.
The formula is rainproof within one hour, which is significantly faster than many comparable products. This fast rainfast window means you can spray in the morning before work and not worry if an afternoon thunderstorm rolls through. Ortho markets this spray for non-edible areas only, so avoid contact with vegetable plants and always shield produce beds with cardboard during application.
Because it targets goosegrass, crabgrass, fescues, and Bermudagrass selectively in landscape beds, this is the best option for gardeners who maintain mixed-use yards with both turf and ornamentals. The trigger sprayer delivers a targeted stream rather than a broad mist, which reduces drift and wasted product. For goosegrass growing around prized perennials, this is the safest precision tool on this list.
What works
- Selective formula protects ornamentals and shrubs
- Rainproof in just one hour after application
- Two-bottle pack provides extended coverage value
What doesn’t
- Labeled for non-edible areas only, not for vegetable gardens
- Not designed for broad lawn application; spot-use recommended
4. Ferti-lome Over The Top Grass Killer
Ferti-lome Over The Top Grass Killer is a selective concentrate that targets both annual and perennial grass weeds including goosegrass, yet it remains safe for use around vegetables, trees, shrubs, and ornamentals. The 8-ounce bottle makes 8 gallons of spray solution when mixed according to label directions, giving you a massive volume of product from a small container. This makes it a strong choice for gardeners who maintain large vegetable plots or mixed ornamental beds.
The formula stops goosegrass growth within just two days of application, which is notably fast for a selective product. Because it is a concentrate, you control the mixing ratio, allowing you to adjust strength based on weed size and density. This flexibility is rare among ready-to-use sprays and is a major advantage for experienced gardeners who want to fine-tune their applications.
Ferti-lome’s label permits application over the top of vegetables and ornamentals — a feature almost no other selective grass killer offers. That over-the-top compatibility means you can spray goosegrass right in the middle of your tomato row without damaging the crop. For edible gardeners fighting goosegrass, this product is the clear specialist in the lineup.
What works
- Over-the-top safety on vegetables and ornamentals
- 8 oz concentrate makes 8 gallons of finished spray
- Visible goosegrass kill within two days
What doesn’t
- Requires mixing and careful measuring for correct concentration
- Not labeled for direct lawn turf application
5. Hi-Yield Killzall Aquatic Herbicide
Hi-Yield Killzall Aquatic Herbicide is a non-selective formula approved for use near water features, ponds, drainage ditches, and other aquatic environments. If goosegrass has taken hold around the edge of a koi pond, along a creek bank, or in a rain garden, this is one of the few products labeled for that specific scenario. The 32-ounce container provides a concentrated solution that mixes with water for broad coverage in sensitive wet areas.
Because it is non-selective, Killzall will kill all vegetation it contacts, including desirable aquatic plants and marginal grasses. Application must be precise — a targeted spray or spot-wicking approach is recommended to avoid collateral damage to cattails or water lilies you want to keep. The aquatic registration means it meets EPA standards for use in or near water bodies, which is a rare certification in the herbicide market.
For most homeowners, this product fills a very specific niche: goosegrass control in wet zones where no other formula is legally labeled. It is not a general-purpose lawn herbicide. But if your goosegrass problem is literally surrounded by water, this is the only option on this list that belongs there. Use it sparingly and with a surfactant for better leaf adhesion on glossy goosegrass blades.
What works
- EPA-labeled for aquatic and near-water applications
- Concentrated formula stretches for large perimeter treatments
- Effective on tough goosegrass in wet conditions
What doesn’t
- Non-selective; kills all vegetation including aquatic plants
- Requires precise mixing and careful targeting to avoid overspray
Hardware & Specs Guide
Active Ingredient Chemistry
The most effective goosegrass herbicides rely on Sulfentrazone for selective post-emergent control. Sulfentrazone is a protoporphyrinogen oxidase (PPO) inhibitor that disrupts cell membranes in grassy weeds while leaving most turf grasses unharmed. Non-selective alternatives like Glyphosate and Diquat offer faster total kill but lack selectivity, making them unsuitable for lawn application. Check the active ingredient list before purchasing — generic “weed killer” labels often omit the specific chemistry needed for goosegrass.
Coverage Area Per Bottle
Coverage varies dramatically by product form. Ready-to-spray hose-end products like Bonide Sedge Ender treat up to 8,700 square feet per 16-ounce bottle, making them cost-efficient for whole-lawn applications. Concentrates like Ferti-lome Over The Top produce 8 gallons of finished spray from an 8-ounce bottle, offering flexibility for targeted spot treatment. Non-selective ready-to-use sprays typically cover 2,000-3,000 square feet per 32-ounce bottle. Match coverage to your infestation size to avoid buying more bottles than necessary.
