SEVEN milligrams per liter
—
Glyphosate is usually represented as a percentage of the volume. Not in milligrams - which is a weight measurement and has nothing to do with volume. You do not spray milligrams, you spray volume:
one liter is only 0.26 of a gallon; 7mg is 0.00025 oz; 1 gallon = 3.7 liters
1 gallon of Roundup “Ready to Use” contains 26 milligrams of glyphosate in solution. Or 0.0009 oz of glyphosate, a very weak solution - commercial spraying uses 3 oz a gallon and achieves visible results within 20 minutes. Its probably so weak because the spray nozzle is cheap and the sprayers are untrained home owners, prone to over-spray, nor aware of the wind, and may even step in the fresh spray. Which is why the label usually say not to expect results for a number of weeks.

You used an awful lot of verbiage to adjust one word, while actually proving my numbers. (26 ml / 3.79 l = 6.86 ml/l)
We are “rounding up” after all. BG
In water based solutions, ml and mg are often interchanged outside the lab or other professional settings. You caught me being lazy.
Now I have to go mix up another batch, as some of the bindweed in the vegetable garden is STILL coming back. The blasted roots go 4+ feet down (I was playing on my mini-excavator and discovered this), so I’m fallowing and spraying the patch this year to try and deal with this nonsense. Also we’re sifting out all the larger stones so the tiller doesn’t break too many tines, they get expensive after the third set.
