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. [Reply]
Do you want a selective herbicide that won't kill grass? Or do you want scorched earth motherfucker?
Selective = 2,4-D broad leaf killer sold by Southern Agriculture. buy a pressure sprayer and have a day. READ INSTRUCTIONS TO MIX. A selective herbicide can become non-selective if mixed incorrectly.
You're probably looking for a sterilizer. We used to use something called Sahara. The name was very fitting. You should be aware that some sterilizers will travel, so any root systems that get to it can have serious issues.
Roundup hasn't killed "everything" for years and will do absolutely nothing for the weeds that will piss you off when they come up few weeks from now. [Reply]
