Chikara is a long lasting total weed killer, meaning, when used at the correct rates it will control most annual and perennial weeds for up to 5 months depending on rate. For best results mix Chikara with a quality glyphosate such as Roundup Pro Vantage 480 or Gallup Hi-Aktiv. This will kill the weeds which are present, and also lay a residual barrier which will prevent any other weeds which try to grow. Chikara is a water dispersible granule formulation for use as a non-selective residual herbicide on natural surfaces not intended to bear vegetation, permeable surfaces overlying soil and hard surfaces (railway ballast only). This is ideal for paths, fence lines & gravelled areas. If you are looking for an alternative cheaper brand then look at Paradise.
