Pine tree needles are turning brown and falling off. Some of the trees have completely died. My neighbor claims there is some type of copper spray that could cure this problem but doesn't have the name of the product.

Do you know the variety of the tree? There are several species specific diseases that might cause this, but I need to know the species to investigate. If you can send me the type of pine tree it is, I should be able to give you some direction in what might be killing it.
