Ok, that's 85 gallons of the more dilute version for regular weeds, but it's still good for comparison. I posting this due to the deal on 16oz less concentrated roundup posted earlier, so people see this deal too. This stuff lasts, so for me it's a better deal and will last me a decade.
This is a potent chemical, so please don't abuse it. It's not good for you or your yard. It can be a really handy tool, though.
