Slasher Organic Weed Killer

100% organic non-selective contact weedkiller.


Slasher is an Organic herbicide that is glyphosate-free and rapidly kills weeds, moss, algae and lichen. It is a natural contact weed control that acts on the foliage, causing it to quickly dehydrate and collapse.

Results are seen as browning and wilting usually within hours of operation.

It is a non-selective contact weedkiller. Thorough coverage is needed when spraying because any parts you miss won’t be killed.

  • Made from natural plant oils.
  • Fast Acting.
  • No Lasting Residue In Soil – 100% biodegradable in a few days.
  • Glyphosate Free.
  • Approved for use on organic farms and gardens.

Use it in gardens, paths, drive-ways, around buildings and as a spot spray in lawns.

Take care when spraying around your favourite plants as any spray drift will also damage them.  Do not apply to wet weeds or if rain is imminent as the extra moisture will dilute the spray and weaken its impact.
