Measure out Zero Weedspray Concentrate as shown on the label for the weed you want to control and mix well with water. For general weeding: Measure out 8-10mL of Zero Weedspray Concentrate and make up 1L with water. Mix well. Unscrew the brush (including cap),and pour liquid into the empty tube. The tube holds 350mL. Replace the brush, ensuring that it is firmly tightened. When ready to begin treating weeds, remove the cap to expose the brush. Ensure the brush is still firmly attached to the cylinder. Touch the brush tip on the ground and apply gentle pressure to open the valve and wet the brush. Proceed with a ‘brush’ and ‘dabbing’ action, applying several brush strokes across the leaves of each weed. It is not necessary to cover all the foliage of each weed. The ‘dabbing’ action lets air in through the brush valve, letting more liquid flow on to the brush. If foliage of wanted plants is accidentally contacted, wash off immediately. When you have finished treating weeds, rinse the brush under the tap, screw on safety cap tightly and hang your Zero® Weeding Brush out of reach of children and out of sunlight. There is no need to empty the contents of the tube. Do not disturb treated weeds for 2 weeks (visible symptoms will appear in 7-10 days).
