We were somewhere around Barstow, on the edge of the desert, when the

saying something like:

Looking for a weedkiller to kill off grass under decks. Weed fabric usually
does the job, but I want to be sure.
Roundup or one its clones.

Isn't that glyphosphate based?
If so, it will only kill what's currently growing.
By design, it is deactivated when it hits the soil,
so it won't stop new plants growing afterwards.

yeah rondup is glyphosate. There are path clear stuffs tho. They persist
a bit longer in the soil.

Ive never found chlorate to be that effective. Except for amateur
explosives, but it isn't even any use for that these days.
