Weedol path clear weedkiller tubes are designed to kill weeds from hard surfaces where you don't want any plants growing. Kills existing weeds to the roots through systemic action so that the weeds won't grow back. Prevents the growth of new weeds for up to three months by creating an invisible residual barrier. Dilute the solution by adding a few drops of weedkiller to water. Apply using either a garden pressure sprayer or a watering can that comes fitted with a fine rose - no measuring, no mess. Ideal for paths, driveways and patios, and not for on lawns or flower beds unless you intend to kill these areas for several months. This pack contains eight tubes of liquid concentrate weedkiller. Warning: Active ingredients: 20 g/l diflufenican and 125 g/l glyphosate formulated as a suspension concentrate (SC). Keep out of the reach of children and always read instructions.
