"I have sprayed caucasian with Roundup only to find it outside the area of spraying and back in the sprayed area within two years, probably from seed. Paul Ohlenbusch, Extension Range and Pasture Specialist for KSU, had considerable experience with old world bluestems in Texas before moving to Kansas seventeen years ago. ...he says, "There are agricultural research centers and experiment stations who have experimented with caucasian and may never do creditable research again because of contamination of study pastures. If that isn't reason enough to avoid it, I don't know what is. Once an introduced species survives one winter and makes seed, you will have it forever."

AKA.......... sod cutter weed
