An alternative would be to use a half rate of round up and a 1 qt per acre rate of simtrol.
For glyphosate?

You can seed the next day.

I may be wrong but I remember reading you are able to seed at the 14 day mark using roundup. I personally would not use round up at all regardless of the soil temp. I would mix simtrol and diquat and maybe even add an ester based 24d before using roundup.

After a quick google, It looks like a 7 day window assuming it worked 100% the first time, therefore, 14 days assuming a second app is needed is recommended.

It is recommending the 7 days only for the kill of the existing plants. The 2nd sentence says that roundup has no soil activity and the 3rd sentence says you can seed the same day.

I have sprayed glyph and put down kbg seed within an hour. Lots of times, no prob. Let it dry and get it done. By the time you clean up your sprayer it's usually aok. If you don't need to push it- don't. If you do- it'll be fine.

The two sentences before state you could seed the same day. Why anyone would kill their entire lawn only to seed it is beyond me. Maybe in a conversion!

While Bermuda is dormant it will not harm the turf one bit. I've done it many time at a rate of 1-1.5qt per acre. It's the easiest and cheapest way to clean up a very grassy lawn.

NC State always shows some slides at pesticide classes of doing it. They've even sprayed well in to march with little damage. It may kill off any emerging new growth but the turf bounces right back.

This is an old slide for common Bermuda I think. I can't find the one I want to show as I'm running out the door. Maybe this afternoon.

Check out slide 18-20 or so....

That's an interesting read there. I'm not ever around bermuda, I wouldn't know it if I was so let me ask as an IA boy: what are you able to kill at only 16oz/acre? I mean what weeds do you hope the glyph is going to kill at that low temp and applied rate? I never knew you guys down South got away with spraying glyph on your turf grass like this. Thanks.
