Good Luck! We have been trying to do this for the past 5 years on our bermudagrass collars. Metsulfuron (Manor, MSM) seems to work best for us. It does move, but does not seem the harm the bent as much as other products. Unfortunately it does not control poa. Probably best to treat a small area and see how comfortable you are with it before doing the rest. Roundup works on poa, but doesn't do much for ryegrass in our experience. Revolver works in hot weather and seems not to move as much as the others SU herbicides (we only use it spot treating with backpacks).
Let us know if you find something that works!
