Moved to a new place back in Nov. 2018. Spent 2019 following the "bermuda bible". Noticed crabgrass slowing taking over a few areas and Celsius only seemed to stunt it. Didn't really care since winter, from what I've read, would kill crabgrass. But not in south Texas apparently. It got down to 28 degrees a few times. Enough to kill the top, but not the roots. During January, I noticed many places where the brown mats of crabgrass could be lifted right out the soil easily. I left it alone since I thought it was dead... but it wasn't. So now my bermuda is coming out of dormancy as well as last year's crabgrass, plus a fresh batch of crabgrass seedlings that have survived prodiamine.
So some pictures. I did an app of quinclorac at the 1lb/acre rate with .72 gallons per 1k sqft plus used 1oz of the MSO duo stick.
After 7 days was thinking it did nothing:

And a day later it magically started going "brown":

I thought it was brown, but on closer look, it was just turning red/purple. Wasn't sure if I was winning after all:

So after a couple of weeks, I did another app of quinclorac with a med app of Celsius. And a week later, it's as strong as ever:

In some areas, there's a serious mess:

In some places, my yard looks green, but once you get up close, you realized it is solid crabgrass:

This was my "test" spot. I've literally drowned this spot several times with quinclorac. The leaves die off, but then it sprouts back from the center mass:

So what to do?! I thought about getting one of those propane powered weed burner/torch things. That is until while getting pictures for this post, I realized that nearly 50% of my front yard is crabgrass. There's still plenty of it hidden under the bermuda thatch in some areas, you can only tell because you start seeing the crabgrass seed heads sticking up higher than everything else after 5 days or so.
I've looked at other chemicals. Nothing seems promising, but I did see that I can get some MSMA. That looks like it can really kill some stuff if you are not careful... sounds good. I'm thinking a 1.5oz rate with 1 gallon over 1k sqft? Should I mix anything with it? Celsius, MSO, fertilizer? I still don't think it will completely kill it. So I think, spray it, wait a week, hopefully it will brown up nicely. Then I'll get a weed burner and go at it with that as well. Sound like a good idea?
