Ah damn. Didn’t use a surfactant, ran out. Do I spray again with the surfactant?

No. Always assume herbicide worked until proven otherwise

So give it the 3 weeks before re spray then?

Make sure you use a surfactant.
Ronk,
Just to verify my thinking yesterday when applying a backpack sprayer mixed combo of Sedgehammer + with its own surfactant mixed in with the pouch and a dash of MSM turf granules. The sedgehammer's surfactant was good for the whole tank's herbicides?

Yes, if it is broadleaf weeds then you'll know what it killed and what it didn't in 3 weeks. Just hit those again.

The surfactant that is already mixed with Sedgehammer will be enough for both herbicides.

Ronk while were talking MSM, I show the application rate as .17 grams per 1K? So I'm going to treat a bunch of weeds and use my 4 gallon backpack and was going to measure out .65 grams. Does that sound right? I know MSM is some tough stuff if you over apply.

Recheck your calculations - I calculate 0.5 gram (1/8 teaspoon), high rate application, per 1000 sq ft for centipede/St Augustine.

Crawdude I know you're usually spot on so I had read to use .5 ounce per acre. I divided that by 43.56 and came out to .311 grams. I am very nervous about it so I was going to go .20 per 1k.
I trust what you're saying just making sure before I do anything dumb. I'm going to drop down from my XR 11004 red tip to XR 11002 yellow tip so I don't get too crazy.

I’ll be home in a minute - I’ll recheck my calcs - and post them. 
Posted on 4/28/21 at 11:08 am to CrawDude
OK my calcs show the following,
MSM Turf application rate
0.25 oz per acre = 0.16 grams per 1000 sq ft
0.50 oz per acre =. 0.33 grams per 1000 sq ft
0.75 oz per acre = 0.49 grams per 1000 sq ft
1.00 oz per acre = 0.65 grams per 1000 sq tt.
I’ve been using the 0.75 oz per acre rate in my lawn, centipede front yard and St Aug backyard with out issues.
The 1/8 teaspoon was recommended in the Clegg’s winter weed cocktail formula, I weighed a level 1/8 teaspoon of MSM Turf on a precision digital jewelers scale to check the weight and it was just at 0.5 grams as I recall.
ETA: so your calcs are correct. If the label indicates the rate you want to apply will control the weeds you are targeting by all means apply that rate. I just wanted to relay at I’ve not had an issue of damaging either centipede or St Augustine when applying 0.75 oz per acre rate (0.5 g = 1/8 teaspoon per 1000 sq ft) this time of the year. But I do switch to Celsius in the hottest parts of summer/early fall.

I got a MSM question. I've used it the past few summers with pretty good sucess.
I sprayed some yesterday to try to knock back some dollar weed. How soon is to soon to cut the grass? I was wanting to cut Thursday before the rain comes this weekend. I'll probably follow up with a second application in 3 weeks or so

Thanks Craw! Always helps to have someone double check when you don't do this every day for a living.

You’ll be good to cut grass Thursday. Generally 48 hours is the recommended time elapsed between spraying and cutting - 48 hours provides sufficient time for a systemic herbicide like MSM to translocate though out the weed’s vascular system.

I applied Scott's Weed n Feed on my centipede front yard and sprayed Weed Free Zone on my mixed grass backyard last week. Is it ok to use MSM now on the visible weeds like burweed and dollar weed that I can see in my yard? Or do I have to wait a set period of time?

I’d definitely wait at least 2 more weeks before applying MSM and give time for the herbicides in the weed & weed and weed free zone to do their job. Those are systemic herbicides and usually takes 2 to 3 weeks to begin showing their effects. Overdosing can damage your lawn grass.

That is my fill chart for MSM and Celsius.
Posted on 4/28/21 at 5:50 pm to trident
I've sprayed herbicides down without a surfactant, but then went back over lightly with water and a spray nozzle to help with absorption. It may have been easier using the surfactant (to help with absorption) to begin with. It still worked out well, but may have been a little extra work.
