Pathological conditions affecting shade and forest trees. Diseases of both shade and forest trees are caused by the same pathogens, but the trees differ in value, aesthetics, and utility. In forests, disease is significant only when large numbers of trees are seriously affected. Diseases with such visible symptoms as leaf spots may be alarming on shade trees, but they are hardly noticed on forest trees. Shade trees with substantial rot may be ornamentals with high value, whereas these trees would be worthless in the forest. Emphasis on disease control for the same tree species thus requires a different approach, depending on the location of the tree. See also: Plant pathology; Tree
