Pseudocercospora Subsessilis
''Pseudocercospora subsessilis'' is a fungal plant pathogen infecting chinaberry tree (''Melia azedarach''). It is widespread in tropical and subtropical areas on host species of the genera ''Azadirachta'' and ''Swietenia''. It was originally published as ''Cercospora subsessilis'' in 1913 and found on the leaves of the chinaberry tree in Tamil Nadu Tamil Nadu (; , TN) is the southernmost States and union territories of India, state of India.

Before the species was transferred to the ''Pseudocercospora'' genus. The fungal leaf spots can amass to blight the entire leaf and were also capable of rapidly defoliating whole trees in late September. The disease has been reported in several other Asian countries as well as in Cuba and the United States.D. F. Farr and A. Y. Rossman. Fungal Databases. Syst. Mycol. Microbiol ...

Fungal
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ''E ...

Melia Azedarach
''Melia azedarach'', commonly known as the chinaberry tree, pride of India, bead-tree, Cape lilac, syringa berrytree, Persian lilac, Indian lilac, or white cedar, is a species of deciduous tree in the mahogany family (biology), family, Meliaceae, that is native to Indomalayan realm, Indomalaya and Australasian realm, Australasia. Description The fully grown tree has a rounded crown, and commonly measures tall, exceptionally . The leaves are up to long, alternate, long-petioled, two or three times compound (odd-pinnate); the leaflet (botany), leaflets are dark green above and lighter green below, with serrate margins. The flowers are small and fragrant, with five pale purple or lilac petals, growing in clusters. The fruit is a drupe, marble-sized, light yellow at maturity, hanging on the tree all winter, and gradually becoming wrinkled and almost white. ''Melia azedarach'' has a short lifespan, averaging about 20 years. Chemistry Italo et al. 2009 and Safithri and Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azadirachta
''Azadirachta'' is a genus of two species of trees in the mahogany family Meliaceae. Numerous species have been proposed for the genus but only two are currently recognized, '' Azadirachta excelsa'' and the economically important tree '' Azadirachta indica'', the neem tree, from which neem oil is extracted. Both species are native to the Indomalaysian region, and ''A. indica'' is also widely cultivated and naturalized outside its native range. Medicinal properties have been attributed to the resin derived from the trees in the traditional medicine of India. One of the components of this resin has been found to be an effective insecticide; see azadirachtin. Another component is an effective anti-fungal; see '' Azadirachta indica''. These species should not be confused with ''Melia azedarach'', which is a tree in a different genus of the family Meliaceae. Taxonomy The genus ''Azadirachta'' was established by Adrien-Henri de Jussieu in 1830. In 1753, Carl Linnaeus had descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swietenia
''Swietenia'' is a genus of trees in the Melia azedarach, chinaberry family, Meliaceae. It occurs natively in the Neotropics, from southern Florida, the Caribbean, Mexico and Central America south to Bolivia. The genus is named for Dutch-Austrian physician Gerard van Swieten (1700–1772). The wood of ''Swietenia'' trees is known as mahogany. Overview The genus was introduced into several Asian countries as a replacement source of mahogany timber around the time it was restricted in its native locations in the late 1990s. Trade in Asian grown plantation mahogany is not restricted. Fiji and India are the largest exporters of plantation mahogany and wild mahogany remains commercially unavailable to this day. It is usually taken to consist of three species, geographically separated. They are medium-sized to large trees growing to 20–45 m tall, and up to trunk diameter. The Leaf, leaves are 10–30 cm long, pinnate, with 3-6 pairs of leaflets, the terminal leaflet absen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamil Nadu
Tamil Nadu (; , TN) is the southernmost States and union territories of India, state of India. The List of states and union territories of India by area, tenth largest Indian state by area and the List of states and union territories of India by population, sixth largest by population, Tamil Nadu is the home of the Tamil people, who speak the Tamil language—the state's official language and one of the longest surviving Classical languages of India, classical languages of the world. The capital and largest city is Chennai. Located on the south-eastern coast of the Indian peninsula, Tamil Nadu is straddled by the Western Ghats and Deccan Plateau in the west, the Eastern Ghats in the north, the Eastern Coastal Plains lining the Bay of Bengal in the east, the Gulf of Mannar and the Palk Strait to the south-east, the Laccadive Sea at the southern Cape (geography), cape of the peninsula, with the river Kaveri bisecting the state.

Mango Tree Diseases
A mango is an edible stone fruit produced by the tropical tree ''Mangifera indica''. It originated from the region between northwestern Myanmar, Bangladesh, and northeastern India. ''M. indica'' has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus ''Mangifera'' also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion. Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color, which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh. Etymology The English word ''mango'' (plural ''mangoes'' or ''mangos'') originated in the 16th century from the Portuguese word ...

Pseudocercospora
''Pseudocercospora'' is a genus of ascomycete fungi. An anamorphic version of the genus ''Mycosphaerella'', ''Pseudocercospora'' species are plant pathogens, including the causal agent of the so-called South American leaf blight of the rubber tree. The widely distributed genus is concentrated predominantly in tropical regions. ''Pseudocercospora'' was circumscribed by Italian-Argentinian botanist Carlos Luigi Spegazzini in 1910. Species , the GBIF lists up to 1,540 species, while Species Fungorum lists about 1,517 species (out of 1,660 records). Over 1000 species are accepted by Wijayawardene et al. 2020.
