(1876) Septoria cucurbitacearum is a fungal plant pathogen infecting cucurbits. Symptoms of Septoria leaf spot are similar on all the ...
Septoria lycopersici prefers warm, wet, and humid conditions. Disease development occurs within a wide range of temperatures; however, the optimal temperatures lie between 20 and 25 degrees Celsius. [4] High humidity and leaf wetness are also ideal for disease development. [2]
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.
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 malagutii is a fungal plant pathogen infecting potatoes. [3] 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 ...
Leaf spots can vary in size, shape, and color depending on the age and type of the cause or pathogen. Plants, shrubs and trees are weakened by the spots on the leaves as they reduce available foliar space for photosynthesis. Other forms of leaf spot diseases include leaf rust, downy mildew and blights. [4]
Septoria musiva, correct taxonomic name: Sphaerulina musiva (teleomorph: Mycosphaerella populorum), is an ascomycete fungus [1] responsible of a leaf spot and canker disease on poplar trees. It is native on the eastern cottonwood poplar Populus deltoides , causing only a leaf spot symptom.
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.
