A tough weedkiller that is perfect for the effective control of brambles, nettles, dock, woody weeds and hardwood saplings. It can also be used to kill off tree stumps. SBK has been specially formulated to kill weeds and not grass, and can be used on turfed areas. It is also ideal for treating any neglected, non-crop areas. Apply from May to October (June to August for woody weeds) when soil is moist and weeds are actively growing. For tree stumps, the best time for treatment is Autumn or Winter, avoiding April, May or June when the sap is rising. This 500ml pack treats up to 170 square metres. Always read the label on your purchased product before use. Use pesticides safely.
