My beautiful backyard tree has a disease. I don’t know what it is nor how to treat. I’ve tried to trim dead branches but notice the white corpuscle type disease on most of the branches. Can this be cured?

Hello,
I checked each of your images with my PictureThis Plant ID app and it identified that tree as a Star Magnolia (Magnolia stellata) not a Dogwood. Also, those white corpuscles are scale.
Please look at this MSU Article - Identifying and managing magnolia scale at this link:
Identifying and managing magnolia scale - Gardening in Michigan (msu.edu)
The article should tell you everything you need to know. Any other questions regarding this, please let me know.
I hope this helps!
