Don't really catch your question, but 30 ml per liter is a good strong ratio. Some labels tell you to mix less, but not all weeds die if a weaker solution is mixed. Some more hardy weeds will not even turn brown. Also check the active ingredient grams per liter Ours are 480g/L. It differs from country to country as well as other suppliers selling it under another name.
