Roundup Ultra Tough Weedkiller Concentrate is a systemic weedkiller that kills tough weeds right to the roots.

This weedkiller is absorbed by leaves and moves through the entire plant, above and below ground, to destroy nettles, ground elder, brambles, bracken and other tough and woody weeds.

Treat established perennial weeds at the start of flowering to give the best results and spray nettles and ground elder when new leaves have unfolded fully in late spring. Allow seven days after spraying before digging or cultivating soil, to allow time for the weedkiller to move to the roots.


  • Sizes: 500ml or 1 litre concentrate
  • Super concentrate formula for killing tough weeds
  • Ideal for treating large areas
  • Degraded in soil by micro organisms
  • Keep children and pets away from treated areas until the spray has died
  • Visible results in as little as 2 days
