I left my container of glyphosate concentrate outside and the label has disintegrated. Can anyone read theirs and tell me what the dilution rate is? I know different brands may be different, but it's better than just guessing! It's a yellow bottle, probably from wilkinsons iirc, but any brand will be a bit of a guide.

Is it "real" concentrate at the 360mg active ingredient per L or the domestic concentrate at much less (80 I think) ? If its the real concentrate then 20ml per L is in the right ball park.

I got mine in Wilko's too but got the pre- measured soluble sachets. That's an 8g sachet to a litre of water.

I doubt it's the real stuff. Any idea what the domestic rate might be?

I would guess about 4 times as much to give the same strength as the commercial stuff. However it will work at much lower strengths & be easier to apply using non pro sprayers if weaker.
