Grass Killer

[JohnD]

Is there a weedkiller available now to kill couch and other grasses, for example in a flowerbed or rhyzomes burrowing under a fence? I did at one time have some but have not seen it for a while.

Do you mean a selective which will only kill grass? I wish it existed but as far as I know it doesn't. But whoever develops one will make a killing.

yes, that's right.

I have had one before, I have an idea it was (is?) used in agriculture where grain crops had previously been grown and were coming up through the new crop. It was marketed to kill couch.

Can't find it on web search.

A quick search implies its no longer available. As i said i'm amazed with modern pesticide advances that there is no selective just for grasses.
