Any idea what it is and how I can correct it? Pictures tell the whole story. Pears develope black spots and shrivel up. If anyone can help let me know.

Is now the time to spray my pear tree? No buds opening as of yet.
Be very careful with copper, if you don't know what you're doing you can burn all the leaves off the tree, russet the fruit, and even kill the tree.Apparently lyme sulfur has been banned. So copper would be the alternative. Or just keep up with the fungicide sprays. Starting when the buds have opened and you see some green.
