How to spray buffalo grass for weeds, with out killing it.

Herbicide/weed killer story in the courier mail today! They are concerned about glyphosate use and mentioned Round up?? Round up is just one of 82 varied herbicides containing glyphosate? Get it right morons! Sure Monsanto first invented it, but so many other companies make their own now its not funny. Anyway yates "lush" is the big one these days, the only herbicide to be safe to spray on buffalo and couch grasses to only kill weeds, finally something to get us away from the stinking Kamba in dicamba, nasty shit that one, it kills buffalo as well as weeds!
