What's the best all around commercial grade selective broadleaf herbicide you've used?

That can be safely used on southern lawns (St. Augustine grass, etc)? Some that I can think of are listed below with their active ingredient(s) in parentheses.

ProSedge (Halosulfuron-methyl 75%)

Celsius (Dicamba 57.4%, Iodosulfuron-methyl-sodium 1.9%, Thiencarbazone-methyl 8.7%

Blindside (Metsulfuron 6%, Sulfentrazone 60%)

Dismiss (Sulfentrazone 39.6%)

Tenacity (Mesotrione 40%)

MSM Turf/Manor (Metsulfuron Methyl 60%)

I've read some good reviews and testimonies of those that have used MSM, especially for the price (about half the cost of most of the others listed). I'm really not too familiar with these products, but it looks like Celsius has several active ingredients that may work better than the others. Any input or personal use experiences is greatly appreciated!

Wouldn’t it matter what you’re trying to kill?

Celsius for me. It’s worth the money.

Yes but I'm talking all around, works on the most weeds, etc.

I got plenty currently in my yard...dandelions, thistle, nutsedge, wild strawberries, dollarweed, clover, and dallis or crabgrass to name a few.

Just for broadleafs? MSM because of price. What makes Celsius so good is that it also controls some grassy weeds.

May bite the bullet and just get the Celsius for my next application...I'm sure I have some grassy weeds too!

Since you have sedges and crabgrass, I think blindside would be good.

Maybe Celsius and spike it with sedgehammer?

Good luck with the dallisgrass, unless you can get your hands on some MSMA (not to confused with MSM).

Total Tribute works on dallis grass. Only in Bermuda though.

If you are backpacking it Celsius will last forever. If you are blanket apping it a 10oz bottle will fill 300 gallons of water. At a 2G rate 300 gallons will cover 150,000 square feet.

I'm guessing it'll kill surrounding St. Augustine grass too? I'm to the point that I don't even care if it kills a few patches of St. Augustine grass with it...as long as it kills the dallisgrass too!

Forgot about Tribute. That's expensive as hell, too. Luckily I know the guy that runs the local co-op and he gets me MSMA when I need it.

What exactly am I looking at here? One side you used Celsius and the other side you used MSM?

Fill me in on the difference between these 2 methods.

Have a question about celsius.

MSMA works best when nights are warmer and just isn't great at this time of year.

Will Celsius work right now (I'm in Memphis where lows are mid 50s to 60s)?

ETA: Will it kill poa annua?

Spraying out of a backpack at .67 gallons per 1000 square feet or spraying from a tank at 2 gallons per 1000 square feet

It will work when it’s cooler out. Not much effect poa. You can spray atrazine and certainty on poa. If you have bermuda and it’s already greening up you don’t want to spray it.

Can I just use a 2 gallon tank sprayer and at slow/steady pace (with sweeping motion in front of me left to right) go back and forth covering my entire yard?
