Kikuyu in St. Augustine

I have a St. Augustine lawn that is being invaded by Kikuyu. What can I do to get rid of the Kikuyu without harming the St. Augustine. I was looking online and found a product called Fusilade. Will this have any affect on the St. Augustine. Any information provided would be helpful.

rexus31, I have done an extensive search of the published literature and I can find no mention of any research on kikuyugrass control in St. Augustinegrass. There is limited research on control in bermudagrass, and high seeding rates and the use of adapted varieties of tall fescue were shown to reduce but not stop the spread of kikuyugrass. However, I can find no attempt to use some common postemergence herbicides on kikuyugrass, such as Manor (metsulfuron-methyl) and Manage (halosulfuron), so there may be some things that can be tried experimentally.
