Premixed for easy and effective weed control, this weed killer starts to work in hours. The Pump 'n Go sprayer system will give 3 full minutes of continuous spray, which is the longest spray action of any ready to use weed killer available. Thus combining rapid treatment of large areas with the convenience of being ready to use. For use on unwanted vegetation, it is absorbed by the leaves, and moves throughout the entire plant, above and below ground, to destroy annual and deep rooted perennial weeds, including grasses, dandelions, docks, bindweed and thistles. It is inactivated immediately on contact with soil and is then broken down by soil micro-organisms, to allow replanting.
