Celsius and surfactant
Posted on 7/18/21 at 8:39 am

I am about to spray Celsius for the first time in my St Aug lawn. Should I use a surfactant? Weather app says a high of 88 but seems it’s been hotter than that.

I think as long as it’s not above 90 when you apply it. At least that’s my understanding.

Yes - use surfactant - a couple teaspoons per gallon. It’s common to have some temporary yellowing of the St Augustine post spraying - it will recover.

Sounds good. I don’t know what all weeds I have. Haven’t kelts you on the ore emergent so there is a mix of things. What rate should I mix, just use the higher rate? I do have some dallisgrass. Maybe some VBW.
Edit: looking up a few on the .113 oz list and I have a cpl of them so I’ll just roll with that for this application.
Need to look up how to measure this stuff out. Never have and it looks like the measurements on the cap are pretty big. Using a 4 gal backpack sprayer.

I came across this chart:

Yes - go ahead and use the highest rate - that’s is 3.2 grams (0.113 oz) per 1000 sq ft. Anticipate re-spraying in a few weeks, particularly if you have have perennial weeds like VBW and Dallisgrass.
Start using pre-emergent this fall (Sept/Oct) and again in late winter (Feb) and it will cut down (not eliminate) on the the annual weed problem dramatically - but not the perennial weeds like VBW and Dallisgrass.
Always feel free to post pics of weeds if you want them ID’d - many on the board can do that for you. If you happen to have sedges in the lawn, like yellow or purple Nutsedge, you need a separate herbicide to control those, like Sedgehammer.

Follow the fill chart I posted. Just know that Celsius won’t kill dallisgrass.

Ahhh that chart is great thank you!
Yes. I have sedge in some spots but I use sledgehammer in a 1gal for that. It’s not bad mostly in my garden area.
I know it won’t kill the dallisgrass. I have to dig that up or nuke it with roundup. I tried the cotton glove then hitting the blades but didn’t get it all so the clump started coming back.
I have some empty lots next to me (weed fest) so I get a lot from there. I have used high yeild pre emerg here and there in the past. And have had good intentions to get more regular with it but haven’t. So I’m trying to get on top of it now. Yard looks good overall but there are spots. I cut on the highest setting on my zero turn to choke some out. I may post some pics later.
I’m using high yeild spreader sticker. Guess that chart is for any kind of surfactant?
Thanks!

FFS it’s hot n sticky out there 
Hope I got the measurements right. Do y’all use a scale or just eye it up on that measuring cap?
I don’t suppose this stuff controls Bermuda grass? I have that all over. If I get my st aug thick it’s not as bad but it struggles in some spots.
Here are a few that I have a bunch of patch’s of.

I personally use a little digital jewelers scale - about $15 on Amazon. Photo at bottom.
Celsius doesn’t control Bermuda, best you can do with St Aug is to cut it high, 3 inches +, let it (hope it) crowds out the Bermuda over time (years, not months).
You have a good variety of weeds.
Not sure what the feathery leaf weed in top photo is - is not chamberbitter - I’ve seen it before but not in my lawn.
Obviously Virginia Buttonweed - white flowers.
3rd and 4th from bottom photos, Spurge and Lespedeza (Celsius will control).
Also some Kyllinga (bottom photo) - sedge but Celsius will control.
4th photo from top - not sure, maybe Bermudagrass seedheads?
Clump “grassy weed”, 5th photo from top - not sure.

The first pic is mimosa weed. I think the seed head is centipede. Not sure about the clumpy grass either. Second from the bottom looks like alligator weed. Craw named the rest.

How long usually to see results. That feather stuff in the first pic is already looking bad but the other stuff looks as it did.
I didn’t know that Kyllinga stuff was a sedge. I have a ton of it all of a sudden. I’ll look to something other than sedge hammer for it because there is so much. Something in a hose end sprayer would be nice.
So I have a mess. I’ll just hit everything I see with Celsius for now until it cools off. Then I can use something in a hose end sprayer to get the whole yard. Then start up and keep up with pre emergent. I already cut at max height on my zero turn.
Is there anything product now in a hose end for Kyllinga and other jut sedge I can shower the whole lawn with in this heat?
I also have some certainty but it says manufacture date is 2013. Too old to use? I store everything in my garage. Is that too hot for it all?
Thanks!

Celsius will control green kyllinga. It won’t control yellow or purple nutsedge. See if prosedge is cheaper than sedgehammer.
Posted on 7/18/21 at 2:58 pm to ronk
When y’all say control…does that mean I won’t get rid of it completely (kill)?
Posted on 7/18/21 at 3:14 pm to NOLAGT
Control=dead. Celsius usually takes 7-14 days for results.
Posted on 7/18/21 at 4:25 pm to ronk
Roger. Safe to cut in a day or two?
Thank y’all for the help, I’m sure I’ll be back

Yes. You can cut in a day or two. I normally wait 2 days.

Does anyone know if that chart is for all types of lawns or just St. Aug? I have a hybrid bermuda Tifway lawn and am looking to use Celsius on mine as well but I want to get the max killing power I can.
Also, Thanks for the surfactant measurement too...I always wondered about that. Does anyone know about the blue tracing dye? I'm gonna read on it...but I figured I'd ask as well.

Same fill chart for all grass types. I have tif and I’ll mix a heavy batch for myself but yellowing comes with the territory
Posted on 7/18/21 at 8:20 pm to ronk
I don’t mind any yellowing if I can hammer the weeds out. I need to be consistent and try to get it in shape.
