Roundup or equivalant

Where to buy? Much prefer Roundup or equivlant to other herbicides as it kill vegetation from the roots not the foliage. Yes, I am aware of the danger to the environment.

Why not just dig or pull up the plants the old-fashioned way instead of poisoning the environment for generations even though it's more "convenient" for you? That's what local gardeners are for. Your question is not one I like seeing my Message Board used for, though I'm sure some "helpful soul" will give you the reply you seek.
