I will be using glyphosate later today and learned something this morning.
Hard water, like in parts of the south east and Staffordshire with Ca ²+ or Mg ²+ levels above 400ppm reduces the effectiveness of Glyphosate. The glyphosate bonds to the minerals in a cation reaction and what gets sprayed on the leaves is less biologically active.
If you must use this evil stuff and live in a hard water area you will get more bang for your buck if you mix with demineralised water.
It's been a long time but I think the pertinent information on what's in your water can be found on your utility companies website.
