Cercospora Leaf Blight (CLB) 5
''Cercospora'' is a genus of Ascomycota, ascomycete fungi. Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus ''Mycosphaerella''. Most species of this genus cause Plant pathology, plant diseases, and form leaf spots. It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known members of the genus. It has a cosmopolitan distribution worldwide. Selected species The GBIF accepts 837 species (as of July 2023); See also List of Cercospora species *''Cercospora acetosella'' - found on Rumex acetosella, sheep sorrel and other docks *''Cercospora aciculina'' *''Cercospora agerati'' *''Cercospora alabemensis'' *''Cercospora alismatis'' *''Cercospora althaeina'' *''Cercospora angreci'' - causes leaf spot of Orchidaceae, orchids *''Cercospora angulata'' *''Cercospora apii'' - causes leaf spot on celery, and found on other plants, including ''Impa ...

Cercospora Beticola
''Cercospora beticola'' is a fungus, fungal plant pathogen which typically infects plants of the genus ''Beta (plant), Beta'', within the family of Chenopodiaceae. It is the cause of Cercospora leaf spot disease in sugar beets, spinach and swiss chard. Of these hosts, Cercospora leaf spot is the most economically impactful in sugar beets (''Beta vulgaris)''. ''Cercospora beticola'' is a deuteromycete fungus that reproduces using conidia. There is no teleomorph stage. ''C. beticola'' is a hemibiotrophic fungus that uses phytotoxins specifically ''Cercospora beticola'' toxin (CBT) to kill infected plants. CBT causes the leaf spot symptom and prevents root formation. Yield losses from Cercospora leaf spot are around 20 percent. Hosts and symptoms Hosts of ''Cercospora beticola'' include sugar beets (''Beta vulgaris''), swiss chard (''Beta vulgaris'' L. subsp. ''cicla)'' and other leafy greens. Symptoms include the random distribution of spots with brownish red rings which eventually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
