Citrus scab is common in certain types of citrus. The main hosts for Elsinoë fawcettii include mandarins (C. reticulata), lemons (C. limon), and grapefruits (C. paradisi) grown in humid climates. Rootstocks like sour orange, rough lemon, Carrizo citrange, and Rangpur lime are also susceptible. Some of the most susceptible cultivars are Temple tangor, Murcott tangor, lemons, and Minneola tangelo. Disease control is important primarily for fresh market fruit, because the disease affects mainly the fruit rind. Young fruits, leaves, and twigs are highly susceptible, but expanded leaves and matured fruits are not susceptible. Many pathotypes exist throughout the citrus-producing regions worldwide. Management of this fungus is achieved mainly by a series of fungicide sprays.
