Slasher Organic Weedkiller contains 525g/L Nonanoic acid, also known as pelargonic acid and is a fatty acid which occurs naturally as esters in the oil of pelargonium plants. It is produced sustainably from biologically based raw materials using an environmentally sustainable patented method of extraction.

Slasher Organic Weedkiller is the first organically registered Pelargonic acid based “burn-down” herbicide developed and manufactured in Australia by OCP.


Slasher Organic Weedkiller can be used safely in and around plants without any risk of off target drift causing irreversible damage when used under normal spraying conditions. No residues also means SLASHER will not cause any sub-lethal residual effects on surrounding plants and unlike some other herbicides will not upset the fertility of soils.


Slasher Organic Weedkiller can be used safety around areas where children and pets play and where other animals might graze after the spray has dried. This makes SLASHER a very versatile herbicide which can be used in just about all horticultural, agricultural and amenity horticultural situations as per DIRECTIONS FOR USE.


Slasher Organic Weedkiller will also control Moss, Algae, Lichen and Liverworts in paths, rockeries, tiled roofs, walls and driveways. This makes SLASHER very useful to Landscapers, Councils and other Parks and Garden officers who can safely use the product not only on weeds but across all surfaces where you might otherwise have to use a more corrosive or soil damaging heavy metal (Copper based) algaecide.
