Vitax SBK Brushwood Killer Ready to Use is a tough weed killer that kills weeds and their roots to prevent regrowth. It is specifically formulated to target and eliminate tough weeds such as nettles, docks, and brambles, while being safe for use on lawns as it does not harm grass. This ready-to-use formulation is convenient for treating neglected, non-crop areas and can also be used to tackle tree stumps. Each 4-litre bottle can treat up to 100m². It offers a triple-effect action: killing the weed, killing the root, and preventing regrowth, and it does not contain Glyphosate.
