Desmodium
''Desmodium'' is a genus of plants in the legume family Fabaceae, sometimes called tick-trefoil, tick clover, hitch hikers or beggar lice. There are dozens of species and the delimitation of the genus has shifted much over time. These are mostly inconspicuous plants; few have bright or large flowers. Though some can become sizeable plants, most are herbs or small shrubs. Their fruit are loments, meaning each seed is dispersed individually enclosed in its segment. This makes them tenacious plants and some species are considered weeds in places. They have a variety of uses. Uses Several ''Desmodium'' species contain potent secondary metabolites that are released into the soil and aerially. Allelopathic compounds are used in agriculture in push-pull technology: ''Desmodium heterocarpon'', ''Desmodium intortum'', and ''Desmodium uncinatum'' are inter-cropped in maize and sorghum fields to repel ''Chilo partellus'', a stem-boring grass moth, and suppress witchweeds, including As ...

Desmodium Intortum
''Desmodium intortum'', known as greenleaf desmodium and also as beggarlice along with other members of its genus, is a species of flowering plant in the genus ''Desmodium'', native to Mexico, Central America, northern South America, the Galápagos, Haiti and Jamaica. A nitrogen-fixing fodder crop, it has been introduced to the rest of the world's tropics, including Africa, India, Australia, New Guinea and Taiwan ''Desmodium intortum'' is used in push–pull agricultural pest management since it contains potent secondary metabolites that are released into the soil and aerially. Inter-cropped in maize and sorghum fields, it repels ''Chilo partellus'', a stem-boring grass moth The Crambidae are the grass moth family of lepidopterans.

Desmodium Uncinatum
''Desmodium uncinatum'', the silverleaf desmodium, is a species of flowering plant in the family Fabaceae, native to Latin America, and introduced as a fodder to various locales in Africa, India, New Guinea, Australia and Hawaii. Although chiefly a fodder, it can also be used for pasture, deferred feed, cut-and-carry, hay, ground cover, and mulch. It is considered invasive in Australia and Hawaii. This species of ''Desmodium'' has also found use in the push-pull technology for pest management where it is grown as an intercrop between rows of a cereal crop to control stem-boring insects and fall armyworm The fall armyworm (''Spodoptera frugiperda'') is a species in the order Lepidoptera and one of the species of the fall armyworm moths distinguished by their larval life stage.

Striga
''Striga'', commonly known as witchweed, is a genus of parasitic plants that occur naturally in parts of Africa, Asia, and Australia. It is currently classified in the family Orobanchaceae, although older classifications place it in the Scrophulariaceae. Some species are serious pathogens of cereal crops, with the greatest effects being in savanna agriculture in Africa. It also causes considerable crop losses in other regions, including other tropical and subtropical crops in its native range and in the Americas. Witchweeds are characterized by bright-green stems and leaves and small, brightly colored and attractive flowers.Sand, Paul, Robert Eplee, and Randy Westbrooks. Witchweed Research and Control in the United States. Champaign, IL: Weed Science Society of America, 1990. They are obligate parasite, obligate hemiparasites of roots and require a living host for germination and initial development, though they can then survive on their own. The number of species is uncertain, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grass Moth
The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae (grass moths) taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes. In many classifications, the Crambidae have been treated as a subfamily of the Pyralidae or snout-moths. The principal difference is a structure in the tympanal organs called the praecinctorium, which joins two tympanic membranes in the Crambidae, and is absent from the Pyralidae. The latest review by Munroe and Solis, in Kristensen (1999), retains the Crambidae as a full family. The family currently comprises 15 subfamilies with altogether 10,347 species in over 1,000 genera.

Fabales
The Fabales are an order (biology), order of flowering plants included in the Rosids, rosid group of the eudicots in the APG II system, Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes (including the subfamilies Caesalpinioideae, Mimosoideae, and Faboideae), Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Rolf Dahlgren, Dahlgren the Fabales were in the superorder Fabiflorae (also called Fabanae) with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quill ...

Faboideae
The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family. This subfamily is widely distributed, and members are adapted to a wide variety of environments. Faboideae may be trees, shrubs, or herbaceous plants. Members include the pea, the sweet pea, the laburnum, and other legumes. The pea-shaped flowers are characteristic of the Faboideae subfamily and root nodulation is very common.

Striga Asiatica
''Striga asiatica'', the Asiatic witchweed or the red witchweed, is a hemiparasitic plant in the family Orobanchaceae. It is native to Asia and sub-Saharan Africa, but has been introduced into other parts of the world including Australia and the United States. Asiatic witchweed is a serious agricultural pest, as it parasitises important crop species, including corn, rice, sorghum, and sugar cane, often causing substantial yield reductions. While it is native to Africa and Asia, it is invasive in farmlands of Kenya, Tanzania and Uganda. In the US, this witchweed was discovered in the Carolinas in 1956. It is considered an invasive agricultural pest, and a vigorous eradication campaign has reduced the affected area by 99% rom to about Biological control can be achieved by growing a ''Desmodium'' (tick-trefoil) undercrop (see push–pull technology). The trefoil can be used as green manure or animal fodder after the harvest. Description ''S. asiatica'' seedlings are not ...

Allelopathic
Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms. These biochemicals are known as allelochemicals and can have beneficial (positive allelopathy) or detrimental (negative allelopathy) effects on the target organisms and the community. Allelopathy is often used narrowly to describe chemically-mediated competition between plants; however, it is sometimes defined more broadly as chemically-mediated competition between any type of organisms. Allelochemicals are a subset of secondary metabolites, which are not directly required for metabolism (i.e. growth, development and reproduction) of the allelopathic organism. Allelopathic interactions are an important factor in determining species distribution and abundance within plant communities, and are also thought to be important in the success of many invasive plants.
