    AHHHH! I have plenty of those in my back yard! I havent tried to kill them I just pull them up. The leaves slip from the root or stem or whatever its called so sometimes all you pull is leaves and the root stays, I hate em!

    My guess is johnson grass and MSMA will smoke it. Good Luck.

    1.0 to 1.5 oz per gallon of MSMA should do the trick.

    It looks like a type of grass. Maybe in the pampas grass family? Not sure but if it is like pampas grass it is a pain in the azz to get rid of. MsMa is the stuff to put the smack down on it.

    its going to be johns grass....that stuff is hard to kill. We had 250 acres of that stuff great for cows but damm its tuff....we would disc it under each year and all we did is piss it off.

    What you have is definately Johnsongrass. I have sprayed this stuff for 20 years for Maryland Dept. of Ag. In Md. johnsongrass must be controled by law. There is NOTHING that will kill this with one or two sprayings. MSMA will only burn it off. Roundup works but takes several years of spraying. The chemical that works far and away the best is Plateau. It is a farm chemical used in CRP acres. Two or three sprayings of Plateau will knock it out but it is very expensive(about $300.00 per gal.) and hard to get. My suggestion is keep up with the RU unless you don't want the brown out, then you could go with any selective grass killer. Most any of them will burn it down. If that johnsongrass has been there any length of time the rizomes on those plants could be running 10 feet or more. You have to have something that will translocate in those roots. This is one tough perennial!!!
