Does anyone know how to get couch out of buffulo grass? what spray would I use?

Answer 1

You have to dig it by hand, and any bit you leave behind grows again.  

If you have clumps of it, spraying just the clump with glysphate works, but you have to be careful to avoid the other grass.

Answer 2

(UK) It's a tall order to get a weed species of grass out of your desired grass species, as chemical controls rely on differences in chemistry and leaf structure to be effective. I've battled against couch (Agropyron repens) in my garden for years, and although I get a certain satisfaction from pulling some of the plants and the runners, I think it's a case of being limited to control rather than eradication.

I found this link which will tell you what you're up against.
