In summary: When you have dense weed coverage do you use celsius and hope the grass fills in or glyphosate and reseed.

So I've expressed several times on this forum that I bought a home last year where the lawn was neglected for more than a decade. There are areas where it's all weeds. I need help with a plan of action. I have Celsius and considered broadcasting it. Then I got to thinking - Celsius has a 90 day wait period for new seed. If I nuke my lawn and end up with huge bare spots I'm stuck with them for way too long. However, I don't think using glyphosate is a perfect answer either because I don't need to do a whole yard reno (not to mention i don't have irrigation). What would you do? The photo below is about 100 square feet of pure dollarweed and representative of several areas in my lawn. What's going to happen if I use Celsius?

I'm considering using glyphosate on half the lawn and doing a reno..... then when it fills in doing the other half. Doing the whole thing isn't in the picture right now, because I'd have to walk my dog on a leash several times a day in the front lawn until the backyard filled in (unless you think my dog can walk freely on a newly seeded lawn).

Celsius because I see some grass that looks like bermuda in spots. If you get the weeds off of it and not kill the bermuda, it'll explode in the summer if you keep it water and throw some fertilizer on it

Nuke and sod. $1-$1.50 a square foot and done.

For small areas, I choose the nuclear option as well. To make sure, I am a big believer in total kill combinations. Never do I trust Glyphosate or RoundUp to turn weed messes into dirt. For broadleaves, I like to add either 2,4-D or Crossbow to the application. I am not done with the area after chemically killing either. I use one of these to remove seeds, stems, leaves, etc.

This does not have the capacity to heat the soil deep enough to kill roots the first time, however, it does a good job of incinerating the dead weeds and leaving a clean surface.

I like this option too and you could do it in sections. I'm not sure if you want to go with bermuda or centipede but you could either call a local sod farm and see if you can pick up just a few squares sod or I know around here Lowe's and Home Depot and even some local Farmers Market/Nursery's sell it by the square but it's generally Centipede for some odd reason.

@Rackhouse Mayor This area seems to have a lot of shade in the picture, how much shade/sun does this area receive?

@Redtenchu that particular area gets 6+ hours of sun. The photo was taken in the evening. However, a lot of my yard is nearly full shade due to the position of my shop.
