How do you know how much you need till you know the dilution rate?
What are you trying to kill?

I was not aware of the dilute factor. The only stuff I have bought in the
past was ready-diluted.

I want to kill (thoroughly) all vegetation that eppears on a stretch of
gravel driveway, with as little effort and expense as possible.
