How Does Roundup Weed Killer Work?

This is the place where we take a closer look at what makes Roundup different to other competitor weed killers. A glimpse of the advanced technology that has been applied to create the World's best selling weedkiller.

The Science

The most advanced weedkiller on earth

Roundup incorporates a highly effective systemic action, developed originally by Roundup for the agricultural industry. Here’s how it works:

  • Roundup is sprayed on to the leaves of the weed
  • It's absorbed through the leaves and enters the plant's sap stream
  • Roundup is carried to the growing points of the weed’s roots and shoots
  • Roundup kills the leaves, shoots and roots
  • Soil is left ready for replanting

Because it kills right down to the root, Roundup will eradicate almost all weeds, including deep-rooted perennials such as Bamboo, Paspalum and Oxalis.

Why is Roundup effective?

Thanks to advanced weedkilling technology, honed over many years, Roundup is one of the safest weedkillers available when it’s used correctly.

One of the reasons for this is because Roundup deactivates upon contact with soil and is degraded by micro organisms.

  • Children and pets can return to the area

Additionally, with Roundup, once the treated leaves have dried:

  • You can carry out new planting

Additionally, the broad range of Ready to Use products, such as Pump ‘N Go and Pull & Spray, allows you to target individual weeds precisely, even in areas where there are plenty of other flowers and plants.

Why have weeds re-grown after several weeks?

Only deep-rooted rhizomatous weeds may re-grow. This will only happen if too little Roundup has been allowed to penetrate the full plant system. In this instance, a re-treatment will be required.

Why has it killed the grass?

Because Roundup is a non selective weedkiller, that means that Roundup is very effective at killing all plants. So be careful to only spray weeds or plants that you don’t want to keep.

Can it be used on paving?

Yes definitely, Roundup is ideal for use on paving, paths and drives as it penetrates right to the weeds roots to ensure a complete kill.
