Those are insects called "scale". This is one of many, many armored scale species. These are much smaller, and harder to spot than some of their larger cousins. Since they cap themselves over with a protective armor "scale" it will be difficult to treat. It takes persistence and a watchful eye.I would suggest removing all that you can by hand. Using water, physically wipe them off of the leaves and bark. This can cut down on what you are going to have to treat. After you have removed as many as possible, you can treat with an insecticide. This can be chemical or natural, depending on your choice. Treatment will need to be done several times.
