How Roundup Weedkiller Works

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 Horsetail, Bindweed and Nettles.

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.

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

  • Children and pets can return to the area
  • 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.

When can my children/pets return to the treated area?

When Roundup has been absorbed by the leaf, the residue will dry. When the residue has dried, children and pets can be allowed back onto the treated areas.

Can Roundup kill Japanese Knotweed?

Yes, but you will need to use Roundup Tree Stump & Root Killer. It may take several applications – please read the label for further advice.

When can I replant/reseed after use?

Roundup is only active in plants and is inactivated on contact with the soil. It is then broken down by soil micro organisms so that you can re-use the soil for re-planting. We recommend that you leave treated weeds for about 7 days before digging or cultivating the soil to allow Roundup to move to the roots of the weed.
