Greasy spot fungus can wreak havoc on citrus trees if not controlled. The fungus is shown on both sides of the leaf. Prevention is easy. Remove all fallen leaves which are the source of more fungus and do not get water on the leaves if possible. Treatment if necessary is with a copper based fungicide.
