Septoria ampelina is a fungal plant pathogen that affects grapes causing septoria leaf spot. [1]
Septoria are ascomycete pycnidia-producing fungi that cause numerous leaf spot diseases on field crops, forages and many vegetables including tomatoes which are known to contract Septoria musiva from nearby cottonwood trees, and is responsible for yield losses. The genus is widespread, and estimated to contain 1072 species. Pycnidia produce needle-like pycnidiospores.
The cereal grain wheat is subject to numerous wheat diseases, including bacterial, viral and fungal diseases, as well as parasitic infestations.
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.
Septoria aciculosa is a fungal plant pathogen infecting strawberries. This pathogen primarily affects coniferous trees, particularly those in the pine family (Pinaceae). This fungus is known to cause a specific disease called "needle cast" or "Septoria needle cast."
Septoria azaleae is a fungal plant pathogen infecting azaleas.
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 citri is a fungal plant pathogen infecting citruses.
Septoria cucurbitacearum is a fungal plant pathogen infecting cucurbits. Symptoms of Septoria leaf spot are similar on all the cucurbits infected.
Septoria fragariae is a fungal plant pathogen affecting strawberries.
Septoria helianthi, also known as Septoria leaf spot, is a fungal plant pathogen infecting sunflowers.
Septoria lactucae, or lettuce septoria blight, is a pathogenic leaf fungus that is found on lettuce.
Septoria pisi is a fungal plant pathogen infecting peas.
Septoria pistaciae is a fungal plant pathogen infecting pistachios. It causes a disease known as septoria leaf spot in the leaves of pistachio, along with the related species septoria pistaciarum and septoria pistacina.
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.
Septoria lycopersici is a fungal pathogen that is most commonly found infecting tomatoes. It causes one of the most destructive diseases of tomatoes and attacks tomatoes during any stage of development.
Septoria secalis also known as Septoria Leaf Blotch is a fungal plant pathogen infecting rye.
Septoria glycines is a fungal plant pathogen that causes leaf spot on soybean, a disease that is also known as brown spot. The disease leads to early defoliation of the plant, but does not normally cause severe reductions in yield. The fungus overwinters on infected soybean straw and is spread by wind dispersal or rain splash.
Septoria malagutii is a fungal plant pathogen infecting potatoes. The casual fungal pathogen is a deuteromycete and therefore has no true sexual stage. As a result, Septoria produces pycnidia, an asexual flask shaped fruiting body, on the leaves of potato and other tuber-bearing spp. causing small black to brown necrotic lesions ranging in size from 1-5mm. The necrotic lesions can fuse together forming large necrotic areas susceptible to leaf drop, early senescence, dieback, and dwarfing. Septoria malagutii has been found only in the Andean countries of Bolivia, Ecuador, Peru, and Venezuela at altitudes of near 3000 meters. Consequently, the fungi grows and disperses best under relatively low temperatures with high humidities, with optimal growth occurring at 20 °C (68 °F). The disease has caused devastation on potato yields in South America and in areas where this disease is common, potato yields have been seen to drop by 60%.
Mycosphaerella eumusae is a fungal disease of banana, causing Eumusae leaf spot. Its symptoms are similar to black leaf streak. M. eumusae is the predominant Mycospharella of banana in mainland Malaysia and in Thailand, and is present in Mauritius and Nigeria. Septoria eumusae is an anamorph of Mycosphaerella eumusae.
