To late to broadcast spray for spurge and sedge?

I just took on a new client and since I usually take on new lawns early in the season, they are usually looking pretty good at this time of year. I want to get a jump on the weeds but don’t want to do something that will hurt it rather than help. I am planning on broadcast spraying Celsius and spot spraying the sedge with Sedgehammer. I also have MSM I can hit it with if it cools down a little more. I’m in south east GA and temps have been 85-75ish lately. Thanks

Drainagehelp--now that is a good question!
What surfactant is best?
Is it worth paying a bit more?
Does the herbicide already include a surfactant?
No one knows--or at least they are not saying it out loud.
Myself, I prefer a silicone type.

Most surfactants really help kill oxalis. They seem to attack the waxy leaves.
I suspect that if surfactants otherwise improved the herbicide effectiveness--then--their advertising would show this. You would see side by side tests, with data and photographs.
So shop around, consult the web, ask the salesman for proof.

I will be right back.
I am testing a product on spurge this week--but spurge is old and tough at this time of year.

Cannot add to my post. Cannot find the "edit" feature.
I do, of course, agree with the use of surfactants on nutsedge.
I think the slick vertical leaf blades would shed too much of any herbicide (like Sedgehammer.)
Same idea applies to wild garlic in spring.
Surfactants are cheap in a backpack or hand sprayer. An ounce per gallon. In a 200 gallon tank--not so much.
I would like to see data as to what percent a particular surfactant improves weed control.
Without data you might as well use the cheapest.
There--the edit feature works OK if you are quick about it.
You can get an idea of how the herbicide spray solution wets the leaf surface by spraying a slick surface--a plastic dumpster or truck fender for instance.

I think Quicksilver might still work.
Actually I tested Speedzone plus T-Zone on spurge, late in the year--and got fairly good results.

I suggest adding surfactant--probably helps wet the spurge better.
