Eco-Organic Garden 20L Concentrate Slasher Organic Weedkiller
Pre-order only Slasher Weedkiller is a Registered Organic herbicide that 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 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 favorite 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.

Just a tad expensive when you realise it’s just vinegar and salt. Make your own at home. Seriously what a rip!

Works very well on all sorts of weeds if applied during a sunny day and without rain to wash away. I really hope this is ‘eco-organic’ as claimed. My brief research suggests it is but I’m not a chemist.
