Tar spot is another one of the maple tree diseases. It is not as severe as other types of tree illnesses but nevertheless, it does do damage to the leaves. Tar spot starts out by turning the leaves a yellow color. From there small tar like looking patches start to from and spread on the leaf surface.
Scots pine is the most susceptible tree species, although other conifers can be affected, such as Austrian, jack, mugo, and red pines and, less commonly, white pines. Tree death usually progresses from the top of the tree downward, distinguishing this disease from needle diseases. Needle discoloration is usually the first symptom. Needles change from their normal color to a grayish green color and finally a tan to brown color.
