The Weedol ultra-tough weedkiller is designed to kill tough weeds like brambles, nettles, thistles, docks, and other deep-rooted weeds. The systemic action permeates the roots preventing the growth of the weeds. The fast-action solution gets degraded by the microorganisms to allow replanting. The ready-to-use formula allows you to apply by pulling the trigger to spray the weeds. To prevent the formula from being washed off or blown on more tonto plants, use it in dry and non-windy conditions. Ideal for ground clearance on untidy and overgrown areas but not for use on lawns unless you intend to kill off all the grass. Size: 1L.
