Leaf Spot Disease is characterized by brown, moist spots on the foliage. In a serious attack the spots can enlarge and merge, killing the whole leaf.
The Leaf Spot disease is caused by various bacteria and fungi.
Many houseplants can be infected by Leaf Spot Diseases but Citrus, Dracaena and Dieffenbachia are highly susceptible to this disease.
