It depends what you are trying to kill.
Glysophate will kill everything it touches. There are a ton of broadleaf killing products on the market...just make sure the label says that it targets whatever weed(s) you need to kill. If you are targeting a specific grass (not a broadleaf). Things get markedly more difficult and expensive.
If you want lasting impact, use the post emergent herbicide now and then hit it with a pre emergent now and again in the fall - it will stop seeds from germinating.
Do you, like, teach high school chemistry loochy? [Reply]
we have a spot that was hard to mow so we terraced it off, put down paper, and rocked it. Couple times a year I'll broadcast Preen on it, and for the rando broadleaf weed that does come up, I'll mix up a little 2-4d. If it happens to be anything else, I'll spot spray with generic glysophate.
Overall it stays pretty clean, and the stuff she wants to keep in it stays safe if you aren't out jackassing around when you spot spray. [Reply]
I've used prodiamine as a pre-emergent the past couple years and then glysophate as a weed killer.... the pre-emergent was a huge help last year for someone who saw rock yards as low maintenance before moving here. :-) [Reply]

Go to Wal-Mart and buy a jug of "Total Vegetation Killer", it's Glyphosate/generic Round-Up. You can buy a bottle type or backpack sprayer at either Wal-Mart or Harbor Freight for 10 or 15 bucks. Mix according to the instructions. This is a much more cost effective than buying the premixed Roundup brand. [Reply]
