If you have 5L Clinic Ace glyphosate 360 and want to dilute it in your 7L sprayer to kill Japanese Knotweed what is the best dilution and how many ml of Clinic will be needed?
140 ml of glyphosphate will give you a 2% solution which should be enough. spray the knotweed and wait 10-14 days, then spray again to make sure. good luck
