I actually think the soil and organic matter NOT REMOVED is a Plus to the new sod. I pick up many of these accounts I kill out and they seem to do very well.
Bermuda is hard to kill and does come back up. U of F recommends 4 application two weeks a part of Glyphosate and Fusilade. That is two months and way too long for for commercial work. Also remember Fusilade un-like Roundup has a pre emerge effect and waiting period before sod can be laid.
Bahia is also Hard to kill, but once sod is laid Bahia doesn't come back up like Bermuda will.
