Slasher Weedkiller is a non-selective contact weedkiller.  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 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. Keep pets off treated areas while the spray is wet. Once dried pets can return to the area.


Kills weeds, moss, algae and lichen on contact. Rapid action, desiccating plants within hours. Doesn’t require heat or sunlight to work. Can be used anywhere in the garden and around the house. Active ingredient made from plant oils (GM free). No lasting spray residues (100% biodegradable within a few days). Does not contain glyphosate. Registered Organic for use in organic farms and gardens


The 750ml bottle is ready to use straight away. The dilution rate for the concentrate is 70ml per litre of water. NOTE: Do not spray on porous surfaces without spot testing first. Slasher Weedkiller may cause discolouration on porous hard surfaces like pavers and bricks.
