Looks like it JC, im not an expert though and don't know which strain, so i cant tell you if you'll need a fungicide or a bactericide to eradicate the blight :/

As far as im led to believe some are caused by fungus and some are caused by bacteria, and need different gunk to get them shifted. Some cant even be treated and need the tree to be chopped to prevent spreading to other plants :(

Like i said though im no expert!

Not a disease but an insect pest called Scale insects.
Can be controlled organically or chemically.

I have just sorted this on my own pot grown acers, with a product called "Bug Gun" (contains imidacloprid)
