Slasher Weedkiller


Product Information

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

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.

Sold as a 1L or 5L concentrate.

Dilution rate is 70ml per litre of water so 1L concentrate makes 14L of spray. 5L concentrate makes 71L of spray.
