NZLA Sedge Pro – Sempra Nutgrass Herbicide 25g

Sedge Control for Home Lawns

Introducing NZLA SedgePro a proven solution for controlling sedge in New Zealand lawns, commonly known through products like Sempra.

Active Ingredient: 750g/kg Halosulfuron-methyl

Struggling with nutsedge pushing through your lawn? NZLA SedgePro is a targeted herbicide designed to control sedges without damaging your turf when used as directed.

Built around a proven active ingredient, it’s absorbed through the leaf and moves throughout the plant, working from the inside to shut it down properly, not just burn it off.

What it targets

• Nutgrass / nutsedge (yellow and purple)
• Common sedge weeds found in NZ lawns

How it works

NZLA SedgePro is taken in through the leaf and translocated through the plant, targeting both the visible growth and the underground tubers that cause repeat outbreaks.

You won’t see an instant hit — instead expect gradual yellowing and decline over 2–3 weeks as the plant is fully controlled.

Application rate

1.3g per 100m²

Apply to actively growing sedge for best results, ensuring even coverage across the leaf. I’ve struggled to find a custom spoon that measures exactly 1.3g, but a heaped 1/4 teaspoon is roughly 1.3g if you don’t have digital scales.

Why use NZLA SedgePro

• Selective for use on most established lawnsTargets the root cause, not just the surface growth
• Proven active used globally for sedge control
• Ideal for home lawn applications in NZ conditions

Always follow label directions. Avoid mowing immediately before or after application, and apply when the plant is actively growing for best performance.
