Bonide Sedge Ender Concentrate 16 oz
| Unit Count | 16 Ounce |
|---|---|
| Item Form | Spray |
| Liquid Volume | 16 fluid ounces |
| Active Ingredients | Herbicide |
Bonide Sedge Ender is a concentrated lawn herbicide designed specifically to control sedges and other grassy weeds such as yellow nutsedge, crabgrass, goosegrass, and foxtail. Sold as a 16 oz concentrate, it is mixed according to label rates and applied with a sprayer for spot or broadcast treatments across warm and cool season lawns. Notable features include pre- and post-emergent activity, a formula that starts working on contact, and rainproofing within hours after drying so treatments remain effective through light weather. The concentrate format makes it economical for treating areas from a few hundred to several thousand square feet depending on dilution.

For someone managing stubborn grassy weeds in turf, it offers targeted control without killing desirable grasses when applied correctly.
Best for: Homeowners focused on getting rid of persistent grassy weeds in established lawns who prefer a concentrated, economical product with proven effectiveness.
Less Ideal for: Gardeners who need a non-lawn solution for ornamental beds or those unwilling to handle a concentrated chemical or follow protective and mixing instructions.
- Concentrated formula yields economical coverage when mixed properly
- Effective against hard-to-kill grassy weeds including yellow nutsedge and goosegrass
- Works both pre-emergent and post-emergent for flexible timing
- Becomes rainproof within hours after drying so treatments are less likely to wash away
- Labeled for use on lawns only so not suitable for flower beds or many ornamentals
- Requires careful mixing and protective gear because it is a concentrated herbicide
Verdict: Choose Bonide Sedge Ender when you need a concentrated, lawn-safe herbicide that reliably kills goosegrass and other grassy weeds down to the root.
Atticus Empero Nutsedge Killer, Halosulfuron Herbicide Concentrate (1.33 oz)
| Item Form | Granule |
|---|---|
| Coverage | 1 Acre |
| Active Ingredients | halosulfuron-methyl |
| Unit Count | 1 Count |
Empero is a concentrated granular herbicide that dissolves in water to make a spray for targeted nutsedge control. You measure one level scoop per 1,000 sq ft, mix with water and a nonionic surfactant, then spray actively growing nutsedge in lawns, golf turf, sports fields, and woody landscape areas. The formulation contains halosulfuron-methyl, which moves to the plant tubers for root-level control so treated nutsedge deteriorates from the root up rather than just burning foliage. Practical benefits include a small, easy-to-store bottle with a measuring scoop, rapid-dissolve granules for convenient mixing, and label directions that allow reentry by pets and people once spray has dried. Limitations are that it is a selective herbicide so it will not control every weed type, repeat applications may be needed for heavy infestations, and it should not be used on newly seeded or stressed turf. Users must add their own surfactant and follow label restrictions about turf types and site approvals.
Best for: Gardeners and turf managers who want a reliable, selective solution to remove nutsedge from established lawns and landscape turf while preserving desirable grasses.
Less Ideal for: People seeking a broad-spectrum, one-step weed killer for mixed broadleaf and grassy weeds or for treating newly seeded or stressed lawns should look elsewhere.
- Selectively targets yellow and purple nutsedge and Kyllinga for root-level control
- Rapid-dissolve granules mix easily for fast preparation of spray solution
- Includes a measuring scoop for consistent, repeatable dosing
- Approved for use on many established warm- and cool-season turf species and several non-crop sites
- Requires addition of a nonionic surfactant which is sold separately
- May require repeat applications for large or established nutsedge infestations
Verdict: Buy this if you need a focused, professional-strength nutsedge treatment that works down to the tubers while being safe on most established turf.

Choosing the Right Weed Killer for Nutgrass: Key Factors to Consider
Active Ingredient and Mode of Action
Understanding the active ingredient is critical because nutgrass spreads via underground tubers that require a systemic herbicide capable of moving into root structures. Some chemistries are contact-only and only scorch foliage, which lets tubers survive and regrow. Choosing an herbicide with documented translocation increases the chance of killing tubers rather than just top growth.
Also consider whether the ingredient targets grasses specifically or is a nonselective formula. Grass-selective systemic options reduce risk to broadleaf ornamentals and garden plants, while nonselective products demand careful spot application to avoid collateral damage.
Application Method and Equipment
How you apply the product affects effectiveness and safety. Spot sprays and foam applicators let you treat individual nutgrass clumps while protecting surrounding plants. Broadcast sprayers cover larger areas but increase the chance of drift and non-target damage. Some formulations require dilution, while ready-to-use sprays are more convenient but can be less economical for large infestations.
Consider the nozzle type and pressure for even coverage and avoid over-application. If you plan repeated follow-ups, choose equipment that is easy to rinse and dedicated to herbicide use to prevent contamination of other gardening products.
Timing and Seasonal Considerations
Nutgrass is most vulnerable when actively growing and storing energy in tubers. Apply systemic treatments during warm, active growth periods so the herbicide translocates down into the roots. Avoid applications during drought stress or dormancy when movement into tubers is limited.
Follow label advice on repeat intervals and whether multiple applications are needed across a season. Some treatments require several weeks for full effect and may need follow-up applications to address new shoots from surviving tubers.
Impact on Turf and Ornamentals
If treating a lawn or beds with desirable grasses and plants, you must select a product labeled safe for those species or plan for spot treatment and physical removal. Nonselective products will injure any green plant they contact, so physical barriers or careful brushing-on techniques are useful in mixed plantings.
Remember that soil residuals can affect reseeding or transplanting windows. Choose products with clear guidance on when it is safe to replant or overseed to avoid harming new desirable vegetation.
Environmental and Safety Considerations
Read label precautions about nearby water, desirable wildlife habitat, and edible gardens. Some herbicides degrade quickly while others persist longer in soil. Longer residuals help prevent regrowth but increase restrictions near vegetable beds and water features.
Personal protective equipment and safe handling instructions matter. Consider the proximity of children and pets, and whether you need a product with low odor or that dries quickly to minimize exposure after application.
When Chemical Control Makes Sense
Chemical control is often the fastest way to reduce dense nutgrass populations, especially when tuber networks are extensive and manual removal has been impractical. Use chemical options when infestation covers large areas or when repeated digging has left many small tubers that will resprout.
Before treating, confirm that the target area is actively growing and not stressed by drought or cold. Also assess nearby desirable plants and water sources so you can choose an appropriate product and application pattern.
- Best used on actively growing nutgrass
- Prefer spot treatments in mixed plantings
- Plan follow-up monitoring for regrowth
Nonchemical and Cultural Suppression Techniques
Cultural tactics reduce nutgrass vigor and complement chemical controls. Dense, competitive groundcovers, thicker lawn stands, and improved irrigation and fertilization can reduce space for nutgrass to spread. Repeated mowing or cutting will not eliminate tubers but can weaken plants over time when combined with other methods.
Solarization and smothering with heavy mulch or landscape fabric can work in beds or small patches where chemical use is undesirable. These methods require patience and may take an entire season to significantly reduce tuber viability.
- Smothering works best on small patches
- Improved turf health reduces invasion risk
- Solarization requires several weeks of full sun
Application Tips to Minimize Damage
For spot treatments, apply on calm days and use a shield or towel to protect nearby plants. Apply in the morning after dew has dried for best uptake and before winds pick up. Avoid watering for 24 hours unless the product label allows it, so the herbicide can move through the plant.
Use foam or gel applicators to keep product where it is needed on small clumps. When broadcasting in lawns, follow label rates closely and calibrate sprayers to deliver the recommended volume per area.
- Apply on calm, dry days
- Consider shields for nearby desirable plants
- Follow label reentry and watering instructions
Follow-Up and Long-Term Management
After treatment, monitor the area for new shoots and treat small regrowth quickly. Multiple treatments spaced according to label instructions are often necessary because tubers can germinate over time. Keep a log of application dates and weather conditions to help time follow-ups effectively.
Combine chemical control with improved cultural practices such as overseeding bare spots, improving drainage, and regular lawn maintenance to reduce the chance of reinfestation.
- Record application timing and conditions
- Treat regrowth early and consistently
- Restore desirable plant cover to prevent return
Safe Disposal and Equipment Care
Dispose of leftover mixed spray and empty containers according to local regulations and label instructions. Rinse sprayers thoroughly after use and use rinsate on labeled turf or as directed. Never pour unused product into drains or storm sewers.
Store herbicides in original labeled containers, away from children and pets, and keep an eye on label expiration and storage temperature guidance to maintain effectiveness.
- Rinse equipment immediately after use
- Follow label disposal instructions
- Store products securely and upright
How We Chose the Best Weed Killer for Nutgrass
We focused on products and approaches that specifically address the biology of nutgrass, not general broadleaf or annual weed control. Selection relied on criteria gardeners can verify on product labels and from independent usage reports. Key evaluation criteria included root and tuber translocation ability, measured by the active ingredient type and label claims; speed of visible control, meaning how quickly top growth dies back after application; residual activity in soil, which affects follow-up timing and safety for replanting; application flexibility, covering spot treatments, broadcast sprays, and treating hardscapes; and safety and handling, including label directions for lawns, edible planting areas, and proximity to desirable plants. We excluded products that only list nebulous "weed control" without any evidence of systemic activity or translocation to underground structures. We also eliminated formulations that lack clear instructions for turf or landscape use or that require specialized commercial equipment not accessible to most home gardeners. The final list reflects products and methods that meet these practical, garden-focused filters and address the specific challenge of nutgrass tubers.
FAQ
Can nutgrass be killed with a single application?
Often it takes more than one application to fully suppress nutgrass because tubers can remain viable underground. Systemic products used during active growth have the best chance, but repeat treatments are commonly needed on established patches.
Is it safe to treat nutgrass in a lawn with desirable grass types?
That depends on the product. Some herbicides are grass-selective and safe for particular turf species when used as directed. If you are unsure, use spot treatments or physical removal to protect desirable grasses.
How long after treatment can I reseed or transplant?
Replanting windows vary by product and residual activity. Some labels allow reseeding within a few weeks, while others recommend longer wait periods. Always check the product label for specific guidance before overseeding or transplanting.
Will nonchemical methods alone eliminate nutgrass?
Nonchemical methods like smothering, solarization, and mechanical removal can reduce nutgrass but are often slow and labor-intensive. They can be effective on small patches or when combined with repeated mechanical removal over time.
Can I treat nutgrass near vegetable gardens or water features?
Exercise caution near edible gardens and water. Choose products labeled safe for use near such areas or use physical removal and localized techniques. Follow label restrictions regarding distances and runoff to protect water and food safety.
Final Verdict
Targeting nutgrass requires a clear plan that balances translocating herbicide action with careful application to protect desirable plants. Prioritize treatments during active growth, use methods that reach tubers, and expect to follow up on regrowth. Combine chemical tools with cultural improvements to restore dense, competitive plant cover and reduce the chance of reinfestation. With the right approach and timing, you can control nutgrass while minimizing risks to the rest of your garden.
