Ascochyta Cherimolaer
''Ascochyta'' is a genus of ascomycete fungi, containing several species that are pathogenic to plants, particularly cereal crops. The taxonomy of this genus is still incomplete. The genus was first described in 1830 by Marie-Anne Libert, who regarded the spores as minute asci and the cell contents as spherical spores. Numerous revisions to the members of the genus and its description were made for the next several years. Species that are plant pathogenic on cereals include, '' A. hordei'', '' A. graminea'', '' A. sorghi'', '' A. tritici''. Symptoms are usually elliptical spots that are initially chlorotic and later become a necrotic brown. Management includes fungicide applications and sanitation of diseased plant tissue debris. Some of these pathogens in the genus ''Ascochyta'' affect grass species, including grains.

Chlorotic
In botany, chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green color of leaves, chlorotic leaves are pale, yellow, or yellow-white. The affected plant has little or no ability to manufacture carbohydrates through photosynthesis and may die unless the cause of its chlorophyll insufficiency is treated and this may lead to a plant disease called rusts, although some chlorotic plants, such as the albino ''Arabidopsis thaliana'' mutant ''ppi2'', are viable if supplied with exogenous sucrose. The word ''chlorosis'' is derived from the Greek ''khloros'' meaning "greenish-yellow", "pale green", "pale", "pallid", or "fresh". In viticulture, the most common symptom of poor nutrition in grapevines is the yellowing of grape leaves caused by chlorosis and the subsequent loss of chlorophyll. This is often seen in vineyard soils that are high in limestone such as the Italian wine region of Barolo in the Piedmont, the Spanish wi ...

Phoma Exigua
''Boeremia exigua'' is the type species of the fungus genus, '' Boeremia,'' in the Didymellaceae family. It was first described as ''Phoma exigua'' by John Baptiste Henri Joseph Desmazières in 1849, and transferred to the genus, ''Boeremia'', by M.M. Aveskamp, J. de Gruyter, J.H.C. Woudenberg, G.J.M. Verkley and P.W. Crous in 2010. Desmazières describes the species as occurring on stems and dried leaves, with two varieties: one of which is found on the stems and leaves of a ''Polygonum'' species, and the other on the stems and leaves of ''Ranunculus''. It causes wet weather blight in cotton and it can be treated with systemic copper. Varieties * ''Phoma exigua'' var. ''exigua'' * ''Phoma exigua'' var. ''foveata'' * ''Phoma exigua'' var.
