metsulfuron on amazon or ebay, a few year to life supply (depending on your practices and lawn size) for $30.

The link shows a study where newly seeded princess was sprayed with various herbicides at 2, 4, and 8 weeks after seeding. All grass had some injury but at the 30 and 60 day after treatment (DAT) showed no injury and no weeds.

I found another graph of this study and metsulfuron created a 5% injury at 5 days. At 30 and 60 DAT the injury was not apperent.

Thx bud. I checked it out. It seems that a Princess bermuda lawn that is new can have a herbicide applied to it soon after it's been planted and recover ok. Mine has been around 8 weeks so I guess I'm good to go.

Quick question if your still around. I looked briefly at this metsulfuron on Amazon. I didn't see any info about which grass it's ok to use in and which weeds it kills. I don't know much about herbicides at the moment. Gotta study :)

You can try Weed-b-gone at half strength after the sun goes down. Start off with a very small area to see how the 77 reacts. You normally don't use weed-b-gone if temps are above 80 but i have found that at half strength after the sun goes down seems to be ok on Bermuda.

Monument ( Trifloxysulfuron-sodium) would be an option as well. Make sure you keep the bermuda well fed. Spurge should not be a problem once you have a dense stand of turf.

Try the link below. Search on google 'metsulfuron label' and you will find labels of many products that use metsulfuron as their active ingredient.
I have a p77 and empire zoysia mix for a lawn. I have found 0% damage from metsulfuron on either grasses.

Thx for the info guys. I checked that pdf Botanicabill but it didn't seem to work? I checked out another label for the Manor(metsulfuron) stuff and it said that the lawn has to be at least a year old.

It's funny cuz I've read something like you have to wait at least 3 mowings before putting down a herbicide on bermuda. I've done that already. This stuff is growing quite fast especially with all the damn rain.

So has anyone had experience with metsulfuron on a new lawn(particularly a bermuda one). I'd love to use it but not at the expense of nuking my lawn.

What I would do is mix up a batch (1/2 gallon or less) and do a few test areas. I would definitely do two, one in the sun and one in the shade. Spray like you normally would and waste the rest. Wait 3 weeks to see if any injury occurs, if you have none, mix a new batch and spray.
