Arecaceae
The Arecaceae () is a family (biology), family of perennial plant, perennial, flowering plants in the Monocotyledon, monocot order Arecales. Their growth form can be climbing palm, climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are colloquially called palm trees. Currently, 181 Genus, genera with around 2,600 species are known, most of which are restricted to tropics, tropical and subtropics, subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem, except for the Hyphaene genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of Habitat (ecology), habitat within their range, from rainforests to deserts. Palms are among the best known and most extensively Horticulture, cultivated plant families. They have been important to humans throughout much ...

Fusarium
''Fusarium'' (; ) is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these ''Fusarium'' species are fumonisins and trichothecenes. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some ''Fusarium'' species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of ''Fusarium'' comes from Latin ''fusus'', meaning a spindle. Taxonomy The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concep ...

Pratylenchus
''Pratylenchus'' is a genus of nematodes known commonly as lesion nematodes.Crow, W. TAmaryllis lesion nematode, ''Pratylenchus hippeastri''.EENY-546. University of Florida IFAS. 2012. They are parasitism, parasitic on plants and are responsible for root lesion disease on many taxa of host (organism), host plants in temperate climate, temperate regions around the world. Lesion nematodes are migratory endoparasites that feed and reproduce in the root and move around, unlike the Heterodera, cyst or root-knot nematodes, which may stay in one place. They usually only feed on the cortex of the root.Lesion nematodes. University of Illinois Extension. 1999. Species are distinguished primarily by the morphology (biology), morphology of the stylet (anatomy), stylets.Norton, D. C. ''Ecology of Plant-Parasitic Nematod ...

Radopholus Similis
''Radopholus similis'' is a species of nematode known commonly as the burrowing nematode. It is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas, and it can be found on coconut, avocado, coffee, sugarcane, other grasses, and ornamentals. It is a migratory endoparasite of roots, causing lesions that form cankers. Infected plants experience malnutrition. History and distribution The nematode was first described from necrotic tissue in a species of ''Musa'', the banana genus, in 1891. It is one of the most important root pathogens of banana crops, causing yield losses of up to 30 to 60% in many countries.Banana Nematodes: Pests and Diseases of American Samoa. Number 9.

Phytophthora
''Phytophthora'' (from Greek (''phytón''), "plant" and (), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species cause economic losses on crops worldwide, as well as environmental damage in natural ecosystems. The cell wall of ''Phytophthora'' is made up of cellulose. The genus was first described by Heinrich Anton de Bary in 1875. Approximately 210 species have been described, although 100–500 undiscovered ''Phytophthora'' species are estimated to exist. Pathogenicity ''Phytophthora'' spp. are mostly pathogens of dicotyledons, and many are relatively host-specific parasites. '' P. cinnamomi'', though, infects thousands of species ranging from club mosses, ferns, cycads, conifers, grasses, lilies, to members of many dicotyledonous families. Many species of ''Phytophthora'' are plant pathogens of considerable economic importance. '' P. infestans'' was the infective agent of the potato blight that caused the Gr ...

Phaeotrichoconis Crotalariae
''Phaeotrichoconis crotalariae'' is an ascomycete fungus that is a plant pathogen. In Brazil, it has been found growing as an endophyte on the healthy leaves of fox grape (''Vitis labrusca ''Vitis labrusca'', the fox grape, is a species of grapevines belonging to the ''Vitis'' genus in the flowering plant family Vitaceae.

Setosphaeria Rostrata
''Setosphaeria rostrata'' is a heat tolerant fungus with an asexual reproductive form (anamorph) known as '' Exserohilum rostratum''. This fungus is a common plant pathogen, causing leaf spots as well as crown rot and root rot in grasses. It is also found in soils and on textiles in subtropical and tropical regions. ''Exserohilum rostratum'' is one of the 35 ''Exserohilum'' species implicated uncommonly as opportunistic pathogens of humans where it is an etiologic agent of sinusitis, keratitis, skin lesions and an often fatal meningoencephalitis. Infections caused by this species are most often seen in regions with hot climates like Israel, India and the southern USA. Growth ''Setosphaeria rostrata'' produce mature conidia with a distinct protruding hilum. The conidia are either straight, curved or bent and the septum above the hilum is thickened and dark. The walls are typically roughened and brown to olive in colour and there are typically 7–9 septa, however, some have 4–1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pythium
''Pythium'' is a genus of parasitic oomycetes. They were formerly classified as fungi. Most species are plant parasites, but '' Pythium insidiosum'' is an important pathogen of animals, causing pythiosis. The feet of the fungus gnat are frequently a vector for their transmission. Morphology ;Hyphae: ''Pythium'' species, like others in the family Pythiaceae, are usually characterized by their production of coenocytic hyphae without septations. ;Oogonia: Generally contain a single oospore. ;Antheridia: Contain an elongated and club-shaped antheridium. Ecological importance ''Pythium''-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to ''Pythium''. This disease complex usually involves other pathogens such as '' Phytopht ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caryota Mitis
''Caryota mitis'', known as the clustering fishtail palm or fishtail palm, is a species of palm native to Tropical Asia from India to Java to southern China, now sparingly naturalized in southern Florida and in parts of Africa and Latin America. The species was originally described from Vietnam in 1790. In Florida, it grows in hummocks and in disturbed wooded areas. Botany ''Caryota mitis'' has clustered stems up to 10 m (33 feet) tall and 15 cm (6 inches) in diameter. Leaves can be up to 3 m (10 feet) long. Each leaf is made of many pairs of leaflets shaped like caudal fin, tail fins that give this palm its name. Flowers are purple and grow on hanging spikes. Its fruits turn dark purple or red when they are ripe, they are harmful to humans.Loureiro, João de. Flora Cochinchinensis 2: 569–570. 1790. The tree slowly deteriorates not long after it bears fruit. Uses Cultivated mainly as an ornament plant in Cambodia, where it is named ''tunsaé töch'', traditional he ...
