Cercospora melongenae

''Cercospora melongenae'' is a fungal plant pathogen that causes leaf spot on eggplant (''Solanum melongenum''). It is a deuteromycete fungus that is primarily confined to eggplant species.〔Welles, Colin G. "Cercospora Leaf Spot of Eggplant." Phytopathology 12.2 (1922): n. pag. Web. 09 Oct. 2015.〕〔Vijaya, T., M. Nagalaxmidevamma, and A. Sreeramulu. "Epidemiology of Cercospora Leaf Spot Disease of Brinjal - Process of Penetration." Environment & Ecology 9.2 (1991): 396-98. Web. 10 Oct. 2015.〕 Some other host species are ''Solanum aethiopicum'' and ''Solanum incanum''. This plant pathogen only attacks leaves of eggplants and not the fruit.〔"Eggplant." Eggplant. PlantVillage, n.d. Web. 19 Oct. 2015.〕 It is fairly common among the fungi that infect community gardens and home gardens of eggplant.〔
== Signs and Symptoms ==
Symptoms begin to show on older, lower leaves first due to the proximity to the soil they are the first leaves to receive the inoculum.〔 Lesions can be found on leaves, stems and petioles. The lesions appear small and circular at first and later progress to angular and more irregular shapes. The lesions are usually 4-10mm in diameter, and have light to dark tan concentric spots. Spots appear on the upper leaf surface first and eventually progress to the lower side of the leaf.〔 Upon observation in the field with a handheld scope, signs of condiophores can be seen in the stomata of infected tissue. Later in the disease cycle excessive sporulation can be readily observed in the center of the lesisons.〔 Eventually the lesions will dry up and in some cases fall out. The fungi does not affect the fruit, however yield can be impacted due to loss of photosynthetic material.〔
