St. Augustine is less able to take the common broad leaf weed killer-24D. If, YOU buy the liquid, mix it strong you can spot treat areas where the St Augustine is INTRUDING and it will kill the St Augustine.
Also, bot St Augustine and the Empire Zoysia spread by (sp?) scions-runners. The ones from the empire Zoyzia are under ground the ones from St, Augustine are on top.
You cam use a push pull sometimes called a convex rake to tear out the St Augustine. The trouble is any pieces left behind will grow again.
For this stuff,"my grass can take your grass." You can also use the FACTS to control St Augustine. Both St Augustine and Empire Zoysia will go brown with lack of water. The difference is the Empire Zoysia goes dormant and will come back. The St Augstine goes PERMANENTLY DEAD. Trouble is you can control your sprinklers BUT you cannot control the rain.

The word you're looking for it stolons. Most southern grasses and many northern grasses are what are known as creeping grasses. That means that they have stolons which run on top of the surface and rhysomes that run under the surface.
St Augustines Bent is a very inexpensive southern grass that is used in The Villages and in many common areas. It is a very coarse grass with large, thick runners. It is fairly hardy and like most southern grasses, goes dormant in the winter.
The golf courses down here are planted with various strains of Bermuda which is also a creeping grass and will take over a lawn. Bermuda is a much finer grass and runners are not as thick. You'll find Bermuda on many of the very expensive homes in Florida. It can be cut much shorter than St Augustines or Bahia which are the predominant grasses in The Villages.
Bermuda also goes dormant and turns brown. That is why you'll see the greens, tees and fairways of the golf courses overseeded with an annual ryegrass in the winter. It's a nice look but it takes rough completely out of play.
