I applied celsius about 4 days ago on parts of my lawn that had a rescuegrass issue and it seems to be doing well. But today I noticed some discoloration on parts of the lawn. Could this be due to the herbicide or something else? I also fertilized with some 32-0-0 afterwards if that makes a difference, and took my hoc from 2 1/2" to 1 3/4" the day before I sprayed celsius.

Could definitely be Celsius. When spot treating, I usually mix a light dose, because I tend to be heavy handed when applying. Blanket sprays I will use a medium or high rate depending on temps and adjuvants.

Did you use surfactant?

I did a spot with Celsius and also had burn. Just fertilize and water. Mine recovered within a week.

Yeah I learned that really a blanket spray is better than spot. And if I do spot spray again for whatever reason I am going to do low rate due to it is really easy to get heavy handed. Whereas blanket spray more of a rhythm thing and you'll also get the weeds that may be early stages you can't see.

You'll be fine. Although some folks here will say otherwise, if you apply celsius at over 85 degrees there's a risk of stressing the lawn and discoloration no matter the grass. But it recovers very well with Celsius. Don't over water or fertilize to try and compensate
