Septoria passerinii is a fungal plant pathogen that infects barley causing Septoria speckled leaf blotch. [1]
Luteoviridae was a family of viruses. The family was abolished in 2020 based on evidence that its three genera and seven species unassigned to a genus belonged to two other, existing families.
Pyrenophora teres is a necrotrophic fungal pathogen of some plant species, the most significant of which are economically important agricultural crops such as barley. Toxins include aspergillomarasmine A and related compounds.
The cereal grain wheat is subject to numerous wheat diseases, including bacterial, viral and fungal diseases, as well as parasitic infestations.
The fungus Cochliobolus sativus is the teleomorph of Bipolaris sorokiniana (anamorph) which is the causal agent of a wide variety of cereal diseases. The pathogen can infect and cause disease on roots, leaf and stem, and head tissue. C. sativus is extremely rare in nature and thus it is the asexual or anamorphic stage which causes infections. The two most common diseases caused by B. sorokiniana are spot blotch and common root rot, mainly on wheat and barley crops.
Spot blotch is a disease of barley caused by Cochliobolus sativus. The disease is found everywhere that barley is grown, but only causes significant yield losses in warm, humid climates.
Zymoseptoria tritici, synonyms Septoria tritici, Mycosphaerella graminicola, is a species of filamentous fungus, an ascomycete in the family Mycosphaerellaceae. It is a wheat plant pathogen causing septoria leaf blotch that is difficult to control due to resistance to multiple fungicides. The pathogen today causes one of the most important diseases of wheat.
Phaeosphaeria nodorum is a major fungal pathogen of wheat, causing the disease Septoria nodorum blotch. It is a member of the Dothideomycetes, a large fungal taxon that includes many important plant pathogens affecting all major crop plant families.
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.
Septoria cannabis is a species of plant pathogen from the genus Septoria that causes the disease commonly known as Septoria leaf spot. Early symptoms of infection are concentric white lesions on the vegetative leaves of cannabis plants, followed by chlorosis and necrosis of the leaf until it is ultimately overcome by disease and all living cells are then killed. Septoria, which is an ascomycete and pycnidia producing fungus, has been well known to attack Solanaceae and Cucurbitaceae species as well as many tree species. This genus is known to comprise over 1,000 species of pathogens, each infecting a specific and unique host.
Septoria selenophomoides is a fungal plant pathogen infecting orchids. It causes leaf spots, starting with small yellowish lesions on the plant's leaves and darkening to brown or black. If the infection develops further, the leaves and fruit fall from the orchid and spread the infection.
Pyrenophora teres f. maculata is a plant pathogen causing spot form net blotch in barley.
Septoria secalis also known as Septoria Leaf Blotch is a fungal plant pathogen infecting rye.
Epoxiconazole is a fungicide active ingredient from the class of azoles developed to protect crops. In particular, the substance inhibits the metabolism of fungi cells infesting useful plants, and thereby prevents the growth of the mycelia. Epoxiconazole also limits the production of conidia (mitospores). Epoxiconazole was introduced to the market by BASF SE in 1993 and can be found in many products and product mixtures targeting a large number of pathogens in various crops. Crops are, for example, cereals, soybeans, banana, rice, coffee, turnips, and red as well as sugar beets.

Solemoviridae is a family of non-enveloped, positive-strand RNA viruses which infect plants. Solemoviridae is a member of the order Sobelivirales.
Hordeum chilense is a species of wild barley native to Chile and Argentina. A diploid, it is used or being explored for use in barley crop improvement due to its resistance to Zymoseptoria tritici septoria leaf blotch, its high seed yellow pigment content (YPC), and its cytoplasmic male sterility. It is a parent, along with durum wheat, of the hybrid crop Tritordeum.
Sarrah Ben M'barek-Ben Romdhane is a Tunisian-Dutch crop researcher. She works on developing fungus-resistant wheat strains to reduce the toll of Mycosphaerella graminicola on yields.
Secale vavilovii is a species of grass, native to Turkey, the Transcaucasus, Iraq, and Iran. An annual, it is a crop wild relative of rye and is being studied for its resistance to Fusarium ear blight and Septoria leaf blotch.
