Slasher Organic Weedkiller

biogro certified new zealand logo

Slasher® Organic Weedkiller rapidly kills weeds, moss, algae and lichen. Use it in gardens, paths, driveways, around buildings and as a spot spray in lawns. It works quickly to control weeds, the organic way!

The active ingredients in Slasher® are made from natural plant oils – a combination of pelargonic acid (nonanoic acid) and orange oil terpenes (D-limonene). Pelargonic acid occurs naturally in plants, including geraniums. Orange oil is an essential oil extracted from citrus peel. Together they act on the foliage, causing it to quickly dehydrate and collapse. Results are seen as browning and wilting, usually within 1 hour of application.

Slasher® is a non-selective weedkiller and will control many weed species on contact.
Slasher® is non-residual in soil and biodegrades within a few days.

In Australia Slasher® Organic Weedkiller has been recognised with two Organic Product of the Year awards (2017 Organic Consumer Choice Award and 2017 Australian Organic Annual Awards for Excellence). After 10 years of research and development in Australia, we’re excited to be able to offer Slasher to the New Zealand market.

Spraying Tips:

    • Keep pets off treated areas while the spray is wet. Once dried pets can return to the area.
    • Thorough coverage is needed when spraying because any parts you miss won’t be killed.
    • Take care when spraying around your favourite plants as any spray drift may damage or kill them.
    • Do not apply to wet weeds, or if rain is imminent as the extra moisture will dilute the spray and weaken its impact.
    • Do not spray on porous surfaces without spot testing first. Slasher® Organic Weedkiller may cause discolouration on porous hard surfaces like pavers and bricks.
    • The dilution rate for the concentrate is 70mL per litre of water – detailed instructions can be found on the back of the bottle. Simply peel off the top layer to reveal a second layer underneath which contains the dilution rate and instructions. Peel from the top right-hand corner where it says, “Peel Here”.

Peel back the top layer for instructions and dilution rate

  • If you can’t see a second layer underneath it means you’ve accidently peeled back both layers instead of just the top layer.
  • If you have trouble separating the layers, the information is also in the How to Use and Precautions tab sections above.
  • Alternatively, you can download the entire product label from the Label tab above.

  • Do not apply if rainfall is expected before spray is dry on plant surfaces
  • Do not water the treated area for 24 hours to achieve maximum results
  • Do not apply if heavy rains or storms that are likely to cause runoff from soil are forecast, within 3 days of application
  • Do not irrigate to the point of runoff from soil for at least 3 days after application
  • Do not allow spray to contact or drift onto plants you do not want killed
  • Keep pets off treated areas while the spray is wet. Once dried pets can return to the area
