    Sempra Herbicide

    The Simple Fix for Nutgrass and Mullumbimby Couch

    If Nutgrass and Mullumbimby Couch keep creeping back into your lawn no matter what you do, it’s time to reach for Sempra Herbicide. This clever formula targets those stubborn weeds right at the roots — no more endless pulling or patchy regrowth. Just healthy, even turf you’ll be proud to show off.


    Why You’ll Love Sempra

    • Stops Nutgrass and Mullumbimby Couch in their tracks – Say goodbye to repeat outbreaks.

    • Safe on most turf types – Gentle on lawns when used as directed.

    • Fast, visible results – Weeds start yellowing in a week and are gone in 4–6 weeks.

    • Effortless to apply – Works perfectly in both boom and spot spraying setups.

    • No more wasted weekends – Spend less time fighting weeds and more time enjoying your lawn.


    How to Use

    When to Apply

    • Nutgrass: When new leaves reach about 5cm.

    • Mullumbimby Couch: Once new growth is around 2cm.

    • Always treat during active growth and avoid spraying before rain or frost.

    Mixing & Application

    • Use 65–130g/ha for boom spraying, or 1.3g per 100m² for spot spraying.

    • Always add a non-ionic surfactant (adjuvant) for best results.

    • Apply evenly and delay mowing for two days after treatment.

    Important Notes

    • Don’t use treated clippings around veggies or fruit trees.

    • Keep livestock and poultry away from treated areas.

    • Works well when tank mixed with Dicamba M, Amicide 700, and similar herbicides.


    Final Word

    Sempra Herbicide takes the frustration out of lawn care — giving you clean, healthy turf without the hard work. Once you see how effective it is, you’ll wish you’d used it sooner.

      This product seems to work effectively. It will, naturally, take a few applications to eradicate the nutgrass
