Ascochyta
''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.

Ascochyta Pisi
''Ascochyta pisi'' is a fungal plant pathogen that causes ascochyta blight on pea, causing lesions of stems, leaves, and pods. These same symptoms can also be caused by '' Ascochyta pinodes'', and the two fungi are not easily distinguishable. Hosts and symptoms The host of ''Ascochyta pisi'' is the field pea (''Pisum sativum L.''). ''Ascochyta pisi'' also infects 20 genera of plants and more than 50 plant species including soybean, sweet pea, lentil, alfalfa, common bean, clover, black-eyed-pea, and broad bean. Field pea is an annual, cool season legume that is native to northwest and southwest Asia. Ascochyta blight of peas is one of the most important diseases of pea in terms of acreage affected.

Ascochyta Pinodes
''Didymella pinodes'' (syn. ''Mycosphaerella pinodes'') is a hemibiotrophic fungal plant pathogen and the causal agent of ascochyta blight on pea plants. It is infective on several species such as ''Lathyrus sativus'', ''Lupinus albus'', ''Medicago spp.'', ''Trifolium spp.'', ''Vicia sativa'', and ''Vicia articulata'', and is thus defined as broadrange pathogen. Symptoms Symptoms include lesions on leaves, stem and pods of plants. The disease is difficult to distinguish from blight caused by ''Ascochyta pisi'', though ''D. pinodes'' is the more aggressive of the two pathogens. Epidemiology The disease cycle starts with dissemination of ascospores after which germination pycnidia rapidly develop. Pycnidiaspores quickly disperse by rain splashes are responsible for reinfection over short distances. Consequently, production of pseudothecia An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hy ...
