Is Lime-Sulfur Effective on Fire Blight?

Just curious. I am about to put on the 2nd spray of lime-sulfur (as soon as the snow we just got melts off), but was starting to think about FB. It would be nice if the L-S spray bought a bit of time before I had to worry about FB sprays.

Label does not list that it could help with fire blight. Primary, it’s used for mites.

I spray copper instead at dormant for fire blight.
