Atticus Empero Nutsedge Killer
Active ingredient: halosulfuron-methyl at 75% in Empero. Best for: established warm- or cool-season lawns needing deep-rooted nutsedge control. Why selected: Empero travels to tubers and roots for comprehensive kill. Good for bluegrass, fescue, Bermudagrass, zoysia and other common turfgrasses. Limitations: high potency requires careful adherence to label directions to avoid damage on sensitive varieties. For best results, apply when weeds are actively growing and follow timing guidance on the label.
Sedgehammer Plus Turf Herbicide

Why selected: Sedgehammer Plus defends against nutsedge and up to 25 additional weeds, with a USA-made quality signal. Limitations: may require precise timing in hot climates to maximize uptake; check local timing for optimal results and ensure compatibility with your turf species.

Active concept: hose-end sprayer compatibility for quick, uniform coverage. Best for: lawns requiring a spray-and-go approach with broad weed kill alongside sedges. Why selected: Provides ready-to-spray convenience and targets listed sedges and broadleaf weeds while remaining suitable for well-established cool- and warm-season grasses.

Active ingredient: halosulfuron-methyl at 5% in 13.5-gram package. Best for: small lawns or targeted applications where a compact package is needed.

Best for: lawns with a mix of sedges and grassy weeds across warm and cool-season grasses.

Buying Guide: Nutsedge Control In Turf
What to consider when choosing a nutsedge herbicide
Active ingredient and rate: Halosulfuron-methyl and sulfosulfuron are common choices for nutsedge. Consider the lawn species and tolerance to the active ingredient before selecting a product.
Mode of application: Ready-to-spray, ready-to-use RTS, and pre-mixed formulations vary in convenience. Hose-end sprayers are ideal for large areas with Ortho’s product; granular or packet formats work for targeted treatment with Empero Q-Pak.
Weed spectrum: Some products target a broad array of weeds beyond nutsedge. If your lawn has multiple weed species, choose a product that addresses your primary targets (nutsedge plus common broadleaf or grassy weeds).
Timing and growth stage: Most nutsedge products perform best when weeds are actively growing. Avoid application during extreme heat or drought unless the label instructs otherwise.
Turf compatibility: Verify that the product is labeled for your specific grass types (cool-season vs warm-season) to prevent damage or poor results.
Safety and usage: Follow label directions for application rates, timing, and protective gear. Note any irrigation restrictions after application to maximize uptake.
How to apply nutsedge control effectively
- Identify the nutsedge patches and treat the area evenly for uniform uptake.
- Apply when the turf is actively growing and soil moisture supports root uptake.
- Follow with proper irrigation as directed, and avoid mowing immediately after application if recommended.
