Pear tree was established 30 years ago. It now has brownish black spots on some, but not all, of the leaves. Also, some parts of the branches die off after fruit is established. Dont know what type, cross between William and Conference. The fruit is usually not ready till late September.

This could be caused from some type of fungus. Treat the tree with a fungicide and see of this helps.
