The diseases caused to the leaves due to many factors like micro-organisms, fungi are called leaf diseases or leaf spot. The chief symptom of a leaf spot disease is spots on foliage. The spots will vary in size and color depending on the plant affected, the specific organism involved, and the stage of development. Concentric rings or dark margins are often present. Fungal bodies may appear as black dots in the spots, either in rings or in a central cluster.
