Bermuda Celsius/Certainity questions

Hi,
A bit of lawn background info: I beat it to the ground till recent (lack of knowledge). With help from TLF, I applied these things in last 2 days: for fungus Scotts DiseaseEX, for fertilizer - Vigoro 29-0-4 granule, for insecticide - Ortho B-gon Insecticide granules. I slightly watered them in, I doubt I even put down 0.5inch of water because my lawn was being over-watered till recent (rains and my lack of knowledge). Now I want to go ahead and get on top of the weeds - already gave them a 2-3 week head-start.

About the weed problems: There are a ton of small weeds - broadleaf types from what I gather (ones which look like small plants - having bigger leaves and stuff). Some are the kind which have a purple stem and small leaves all over etc. If i start attaching pictures, there would be more than 10-15. They are rapidly spreading across the lawn.

I read a lot about how good Celsius/Certainity are in the high temps of GA + warm season grass. I intend to buy both of them, mix together and do a spot application as a broad control (tired of trying to ID all of the weeds) first and then figure out what ones remain and counter them with specific chemicals. Before I go ahead and order both the products, I have some questions after reading a lot of posts in TLF about them:

1. Do's and Don'ts of mixing either?
2. When do they NEED a surfactant? GA temps are in the high 80's right now and the forecast predicts them to be mid 90's next week.
3. I keep seeing this in posts- "Yearly Mark". What is this and how important is this?
4. Thoughts on blanket spraying?
5. Anything that either product doesn't outright cover?
6. Would you add any other weed killer to the mixture?
7. I read about the Bermuda Triangle. For future reference, does Pre-emergent (Barricade) need a blanket type application?

Thanks!

1. Wear PPE. Low wind and no rain in forecast (only pre-em should be watered in). Practice spreading 1 gallon of water over 1k sq/ft so you know how fast to walk with your sprayer.
2. Helps under 90. Hurts above 90. Not NEEDED at any temp. In your case, skip surfactant.
3. Not sure, maybe yearly max? If so, don't exceed this amount in a year.
4. Do it, especially if you're seeing nutsedge. You'll be less likely to burn your lawn blanket.
5. Dallisgrass. Paint glyphosate on this nightmare.
6. No, but maybe pre-emergent (prodiamine). If you do, water in the next day (0.5").
7. Yes.

What sprayer do you have? Outrider is much cheaper than certainty.

I bought this sprayer: https://www.walmart.com/ip/Eliminator-2-Gallon-Heavy-Duty-Multipurpose-Pump-Sprayer-000001/496938095. Got it for 12$ in store compared to a 30$ for a similar Chapin Pro product on the shelf.

I read Outrider is cheaper/oz but expensive up front (way bigger container) so I didnt look into it at all and I've been trying to find a price online and haven't found it yet. Can you please link me where I can buy it?

Also, can you please confirm if this is the correct Celsius? https://www.amazon.com/gp/product/B006LC7DD8/ref=ox_sc_act_title_1?smid=A1X6GX01I44OYO&psc=1

I couldnt find Certainity in Amazon but found it here, https://www.domyown.com/certainty-herbicide-125-oz-p-1339.html . Is it a reputed store I can buy from?

Certainty exchange is mostly outrider these days: https://thelawnforum.com/viewtopic.php?f=14&t=2560
You'll need ~3.2 grams to do your 4k sq ft at 1.25 rate.

That's correct Celsius.

Domyown is good. Also check to see if you have siteone locally.
Oh, thanks for the link and confirmations, looks like I don't need to spend 150$. Although, I'm not too sure if I want to give out my home address to someone, I would be glad to drive by to anyone near-by :)
