Atticus Empero Nutsedge Killer herbicide concentrate 1.33 oz — halosulfuron for deep tuber control, low-use-rate

Atticus Empero Nutsedge Killer is a concentrated halosulfuron-methyl herbicide designed to eliminate nutsedge by reaching and disabling the weed's tubers for long-lasting turf control.

For homeowners and turf professionals battling persistent yellow or purple nutsedge, Atticus Empero delivers a targeted, low-use-rate solution. This compact 1.33 oz concentrate dissolves quickly, mixes easily, and is formulated to be safe on most established warm- and cool-season grasses when used according to label directions. Empero focuses on the root tubers that let nutsedge re-emerge, meaning fewer repeat applications and faster recovery of lawn appearance.

How does Empero control nutsedge differently from other weed products?

Empero contains halosulfuron-methyl, a selective sulfonylurea herbicide that moves into the plant and down into the underground tubers. Rather than only burning back the foliage, this mode of action disrupts growth at the source so regrowth is markedly reduced.

• Active ingredient: 75% halosulfuron-methyl for targeted action.
• Systemic uptake reaches nutsedge tubers for deeper control.
• Low-use-rate concentrate reduces storage and measuring needs.

Is Empero safe to use on common lawn grasses?

When mixed and applied according to the label, Empero is compatible with a wide range of established turfs including Kentucky bluegrass, tall fescue, Bermudagrass, and zoysia. Always test on a small area if you’re unsure and avoid use on newly seeded or newly sodded lawns until fully established.

• Suitable for most warm- and cool-season grasses.
• Not for use on seedbeds or recently planted turf.
• Follow state restrictions—product not sold in Alaska or Vermont.

How do I mix and apply the concentrate for best results?

Empero’s granules dissolve rapidly so you can prepare spray solution quickly. Use the specified scoop and add surfactant per gallon of water to improve coverage; treat when weeds are actively growing for highest effectiveness.

• Mixing: 1 level scoop Empero plus 2 teaspoons surfactant per gallon of water.
• Application: Spray evenly over target area; ensure thorough coverage of nutsedge foliage.
• Re-entry: People and pets may return once spray has dried.
• Rainfastness: Sets in about 4 hours, reducing rain interference.

How soon will I see results and what about retreatment?

Visible decline in nutsedge may appear within days to weeks depending on growth stage and environmental conditions. Because Empero works into the tubers, treated areas typically require fewer follow-ups, though heavily infested sites may need repeat applications as allowed on the label.

• Timeline: Initial yellowing or dieback often within days.
• Follow-up: Reapply only if label permits and problem persists.
• Environmental factors: Active growth and warm temperatures improve performance.

Who is this product for? Atticus Empero is aimed at homeowners, landscapers, and turf managers who need a professional-strength, low-volume herbicide to control nutsedge without harming established turf. If you want a concentrated, fast-dissolving formula that targets the tubers and shortens the cycle of retreatments, Empero provides a practical option—just read and follow the label and verify local registration before purchase.
