Bermuda / St Augustine

Just picked up a new lawn in a high end residential area. Yard is a mixture of bermuda and St Augustine. Lot of various weeds, crabgrass, sedge, clover etc.
I am licensed but don't deal with a lot of St Augustine and usually am using a 3way spray for the bermuda. What is my best approach on this lawn. Will be spraying in Sept and will have the lawn full time next year.

Which turf are you trying to keep? How much of each at the property?

Customer prefers the St Augustine, it is about 60 percent St Augustine, 40 percent bermuda with weeds thruout.

Ornamec is a selective herbicide that only kills Bermuda grass.

Why not have both? I have several with mixed grass. I personally think if I was doing this lawn for the first time in Sept [i generally do mine in late sept and early oct] I would use a 3 way or Speedzone Southern with Simazine for the winter then start regular treatments in the Spring. The Crabgrass and such is going to start dying back on its own in a couple months anyway.

IMO it looks like crap. I like 1 turf, with little or no weeds. That's just me though. It's a cheap look. Like they had st Augustine that went south and just threw Bermuda seed down.

I can see your point in a way. On my treated and irrigated smaller lawns the St Augustine will take over and I will admit they look better full. On the larger lawns they may have too many microclimates where one does better than the other and with, lets say, 8k of SA and 20k of Bermuda I do not think it looks bad.

Ornamec is a herbicide that kills most all grasses including St Augustine. The big problem is weed control on St Augustine is. St Augustine is susceptible to most herbicides.

Herbicide can be great but there comes a point when Herbicides can't do the job. Oh sure they can kill off all the weeds, But will you have grass where the weeds were??? One of the reasons I like slow acting Herbicides is because they allow for a Grow in at the same time. But you have to have a high percentage of desirable turf to start with.
