Glyphosate is a non-selective, systemic herbicide used to kill weeds. Glyphosate is effective in killing most plant types including perennials and grasses in many situations including amenity, forestry, aquatic and industrial. It is only effective on plants which are actively growing.

As a weed killer, glyphosate works by being absorbed into a plant through the leaves and stalk, after which it spreads throughout the plant, blocking the plant’s enzymatic system, preventing amino acid metabolism in the shikimic acid pathway. Its effectiveness is in preventing plants making proteins which are vital for the plant to grow.

Following treatment, leaf symptoms on treated plants are a reddening then yellowing of the foliage over days or weeks. As glyphosate circulates throughout the entire plant, right down to the roots, the whole plant is killed and not just the foliage.

Glyphosate can be used to control many annual broadleaf weeds and plants including:

  • Bracken
  • Heather
  • Bulrush
  • Watercress
  • Dandelions
  • Nettles
  • Knotgrass
  • Crabgrass
  • Rhododendron
  • Sedges
  • Rushes
  • Reeds
