Cercospora Arctii
''Cercospora'' is a genus of 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 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 of the species.

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 necrotrophic 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 ca ...

Peanut
The peanut (''Arachis hypogaea''), also known as the groundnut, goober (US), pindar (US) or monkey nut (UK), is a legume crop grown mainly for its edible Seed, seeds. It is widely grown in the tropics and subtropics, important to both small and large commercial producers. It is classified as both a grain legume and, due to its high oil content, an oil crop. World annual production of shelled peanuts was 44 million tonnes in 2016, led by China with 38% of the world total. Atypically among legume crop plants, peanut pods develop underground (geocarpy) rather than above ground. With this characteristic in mind, the botanist Carl Linnaeus gave peanuts the specific epithet ''hypogaea'', which means "under the earth." The peanut belongs to the botanical Family (biology), family Fabaceae (or Leguminosae), commonly known as the legume, bean, or pea family. Like most other legumes, peanuts harbor symbiotic Nitrogen fixation, nitrogen-fixing bacteria in root nodules. The capacity to fi ...

Cercospora Arachidicola
''Cercospora arachidicola'' is a fungal ascomycete plant pathogen that causes early leaf spot of peanut. Peanuts (''Arachis hypogaea'') originated in South America and are cultivated globally in warm, temperate and tropical regions. All cultivars of peanuts are equally susceptible to peanut fungal pathogens; however, ''C. arachidicola'' is an economically important peanut pathogen and is responsible for significant economic losses in the peanut industry, more specifically in the Southeastern, Eastern, and the Southwestern United States. Early leaf spot of peanut can drastically reduce yields, leading to economic downturn of the peanut crop economy. Annual crop losses in the United States range anywhere from less than 1% to greater than 50% depending on disease management and treatment. Host and symptoms ''Cercospora arachidicola'' only infects peanut plants, causing symptoms of brown lesions with chlorotic rings on the stems, leaves, and petioles. The first macroscopic symptom ...

Impatiens
''Impatiens'' is a genus of more than 1,000 species of flowering plants, widely distributed throughout the Northern Hemisphere and the tropics. Together with the genus ''Hydrocera'' (one species), ''Impatiens'' make up the family Balsaminaceae. Common names in North America include impatiens, jewelweed, touch-me-not, snapweed and patience. As a rule-of-thumb, "jewelweed" is used exclusively for Nearctic species, and balsam is usually applied to tropical species. In the British Isles by far the most common names are impatiens and busy lizzie, especially for the many varieties, hybrids and cultivars involving ''Impatiens walleriana''. "Busy lizzie" is also found in the American literature. The invasive alien ''Impatiens glandulifera'' is commonly called policeman's helmet in the UK. Description Most ''Impatiens'' species are herbaceous annuals or perennials with succulent stems. Only a few woody species exist. Plant size varies depending on the species, from five centimetres t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celery
Celery (''Apium graveolens'') is a marshland plant in the family Apiaceae that has been cultivated as a vegetable since antiquity. Celery has a long fibrous stalk tapering into leaves. Depending on location and cultivar, either its stalks, leaves or hypocotyl are eaten and used in cooking. Celery seed powder is used as a spice. Description Celery leaves are pinnate to bipinnate with rhombic leaflets long and broad. The flowers are creamy-white, in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, long and wide. Modern cultivars have been selected for either solid petioles, leaf stalks, or a large hypocotyl. A celery stalk readily separates into "strings" which are bundles of angular collenchyma cells exterior to the vascular bundles. Wild celery, ''Apium graveolens'' var. ''graveolens'', grows to tall. Celery is a biennial plant that occurs around the globe. It produces flowers and seeds only during its second year. The first cul ...
