Belonolaimus Longicaudatus
''Belonolaimus longicaudatus'' (Sting nematode) is a common parasite of grasses and other plant crops and products. It is the most destructive nematode pest of turf grass, and it also attacks a wide range of fruit, vegetable, and fiber crops such as citrus, cotton, ornamentals, and forage. The sting nematode is a migratory ectoparasite of roots. It is well established in many golf courses and presents a problem in turf management. The sting nematode is only present in very sandy soils. It cannot reproduce in heavier or clay soils. History The genus was originally described by Steiner in 1942 but because of WWII the work was not published until 1949 (''B. gracilis'', Steiner 1949). Rau (1958) further refined the anatomical description and clarified the genus to note that there were several species, most common of which is ''B. longicaudatus''.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Iron Clay Pea
Iron () is a chemical element with Symbol (chemistry), symbol Fe (from la, Wikt:ferrum, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 element, group 8 of the periodic table. It is, Abundance of the chemical elements#Earth, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer core, outer and inner core. It is the fourth most common abundance of elements in Earth's crust, element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or Metallurgical furnace, furnaces capable of reaching or higher, about higher than that required to smelting, smelt copper.

Lambsquarter
Lamb's quarter, lambsquarters, and similar terms refer to any of various edible species of herbaceous plants otherwise known by the common names goosefoot or pigweed. There are numerous variations, with or without hyphens and apostrophes, using one word or two, and singular or plural. As a rule, the British English spelling uses two terms with or without hyphen though usually with an apostrophe, while the American English spelling uses one word. * In Europe, the term usually refers to ''Chenopodium album'' (white goosefoot). * In North America, the term usually refers to ''Chenopodium berlandieri ''Chenopodium berlandieri'', also known by the common names pitseed goosefoot, lamb's quarters (or lambsquarters), and ''huauzontle'' (Nahuatl) is an annual herbaceous plant in the family Amaranthaceae.

Fescues
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus ''Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.

Bermuda Grass
''Cynodon dactylon'', commonly known as Bermuda grass, is a grass found worldwide. It is native to Europe, Africa, Australia and much of Asia. It has been introduced to the Americas. Although it is not native to Bermuda, it is an abundant invasive species there. In Bermuda it has been known as "crab grass" (also a name for ''Digitaria sanguinalis''). It is also known by various names as ''Dhoob'', ''dūrvā'' grass, ''ethana'' grass, ''dubo'', dog grass, dog's tooth grass, Bahama grass, crab grass, devil's grass, couch grass, Indian ''doab'', ''arugampul'', grama, wiregrass and scutch grass. Description The blades are a grey-green colour and are short, usually long with rough edges. The erect stems can grow tall. The stems are slightly flattened, often tinged purple in colour. The seed heads are produced in a cluster of two to six spikes together at the top of the stem, each spike long. It has a deep root system; in drought situations with penetrable soil, the root system ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crabgrass
''Digitaria'' is a genus of plants in the grass family native to tropical and warm temperate regions but can occur in tropical, subtropical, and cooler temperate regions as well. Common names include crabgrass, finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. ''Digitus'' is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce. Uses The seeds are edible, most notably those of fonio (''Digitaria exilis'' and ''Digitaria iburua''), ''Digitaria sanguinalis'', as well as ''Digitaria compacta''. They can be toasted, ground into a flour, made into porridge or fermented to make beer. Fonio has been widely used as a staple crop in parts of Africa. It also has decent nutrient qualities as a forage for cattle. Lawns The prevalent species of ''Digitaria'' in North America are large crabgrass (''D. sanguinalis''), sometimes known a ...

Vigna Unguiculata
The cowpea (''Vigna unguiculata'') is an annual herbaceous legume from the genus ''Vigna''. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Four subspecies of cowpeas are recognised, of which three are cultivated. A high level of morphological diversity is found within the species with large variations in the size, shape, and structure of the plant. Cowpeas can be erect, semierect ( trailing), or climbing. The crop is mainly grown for its seeds, which are high in protein, although the leaves and immature seed pods can also be consumed. Cowpeas were domesticated in Africa and are one of the oldest crop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Vetch
''Aeschynomene'' is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic ''Dalbergia'' clade of the Dalbergieae. They are known commonly as jointvetches. These legumes are most common in warm regions and many species are aquatic. The genus as currently circumscribed is paraphyletic and it has been suggested that the subgenus ''Ochopodium'' be elevated to a new genus within the Dalbergieae, though other changes will also be required to render the genus monophyletic. Species ''Aeschynomene'' comprises the following species: * ''Aeschynomene abyssinica'' (A. Rich.) Vatke * '' Aeschynomene acapulcensis'' Rose * ''Aeschynomene acutangula'' Baker * ''Aeschynomene afraspera'' J. Léonard * ''Aeschynomene americana'' L.—shyleaf ** var. ''americana'' L. ** var.
