Celsius question
Posted on 5/31/24 at 4:47 pm

Blanket sprayed at the high rate for the first time a little over a week ago. Starting to see results, also some very noticeable stunted growth and slight yellowing of the grass. One area is Centipede which seems to be fairing better. The area with St. Aug, not so much.
Is this pretty typical of a high rate of Celsius? Should I do anything in the meantime besides mow?

It’s very normal, especially at the high rate. I experienced a bit of this with Bermuda a few weeks ago.
I watered, mowed, and fertilized my way through it. But Bermuda is a champ, so…
St Aug?
The rain should help.
Keep mowing even if you cut just a little bit off. Not sure if you should fertilize. It might not like that.

Celsius at the high rate will stunt St Aug. it yellows my bermuda. Don’t do anything crazy. Fert, mow, and water as normal and it will out grow it.

What is “high rate”? How much we talking about per 1000sf?
Posted on 5/31/24 at 8:37 pm to poochie
.226 oz (one packet) mixed with 2 gal of water

Be careful using when temps will exceed 85. Can cause burn.

I’ve been mixing 0.45 oz in 4 gals water for spot spraying and have noticed that it is tough on Bermuda.

Celsius is named Celsius because it doesn’t have temperature restrictions. You can use it above 90.

Yep - I've cut the rate in half to help with the turf burn. It still works well on the weeds, it just takes a little longer to kill off - but less damage to the Bermuda.
Also be sure to use a surfactant.

Oh yea, forgot to mention I used a surfactant, although I've heard that can cause more stress on the grass. I've got some RGS left I'll probably put down, maybe some liquid iron, and just mow.

Possible, especially if using the high rate.

I did the same with an area of my yard a couple months ago, thought that the st Aug was dead. Just kept watering regularly and it’s come back stronger than ever, looks great.

Do a quick google search. I did a deep dive on this last week since experiencing burn after using the product
I, too, believed this product could be used without temp restrictions. I was told so at the garden center. He was wrong.
I spoke to another garden center and their expert said this is a misconception. He even challenged me to show him on the Celsius label/product description where it says this. I was unable to after trying.
Like most herbacides, you probably won’t experience a burn if applied correctly at 85-90, but it is certainly possible and happened to me on St Aug with temps between 85-90 for the days following application. The higher the temp the higher the burn risk. TIFWIW

No product is going to state all the things that don’t apply to the product. That’s nonsensical.
If there were temperature restrictions then they would be stated. If there are none, then why would they need to include that in writing?
Based on that logic, the label would be endless.

My grass is burned. I’ve been unable to find anywhere official that says it can be used over 85 other than spot treatment.
I promise I would much rather be nodding with y’all right now instead of sharing that my yard is burned from using this product.
Sharing my recent experience and newfound knowledge here seems like the point of this board, no?
Please show me somewhere that this product states it can be used in temps over 85. I’d love to discuss with Bayer, as I will have to remedy my yard that looks like complete shite right now.
Edit: adding that I just read the Turf Tolerance section of Celsius label and it does in fact warn that “temporary discoloration” to grass can result from “hot weather.” So, maybe with fert and some more time my St Aug will recover from the burn. Regardless, I wanted to share my experience so others may benefit from it. I’m happy to give it more time and report back on how it bounces back.

There’s missing info though…
What rate did you use?
Did you add a surfactant?
Did you overlap on your broadcast spraying?
Everyone in this thread knows that Celsius can harm desirable turf grass, but there are ways to avoid that, even above 90°.
Temporary discoloration is what I experienced and I went medium to high rate on a broadcast application.
Everything bounced back in less than two weeks.

One packet .226 oz mixed with 2 gall water. No surf added. Broadcasted a little over one gallon with minimal overlap to roughly 1200 sf. I’m a week out from application.
I’m a week out from application. I was pretty shocked when the expert at an incredibly reputable place was adamant that burn can happen with this product, as it the reason I bought this product over Weed Free Zone due to temps.

Did I miss the grass type?
It’s definitely strong stuff.
I, like you, am unwilling to admit that heat influences results with Celsius.
But I will apply no more than the low rate going forward.
Is your lawn crunchy or just discolored?

It’s St Aug. Widespread discoloration, but not crunchy. The 1/4 portion of the yard that gets the most sun is brown and crunchy
