Solanum Viarum
''Solanum viarum'', the tropical soda apple, is a species of perennial shrub native to Brazil and Argentina with a prickly stem and prickly leaves. The fruit is golf-ball-sized with the coloration of a watermelon. It is considered an invasive species in the lower eastern coastal states of the United States and recently on the Mid North Coast of Australia. Synonyms This species has several synonyms, one of which is particularly ambiguous: * ''Solanum chloranthum'' DC. :''S. chloranthum'' as described by Poeppig based on Otto Sendtner in von Martius is now '' S. velutinum'' :''S. chloranthum'' as described by Philipp Salzmann based on Dunal in de Candolle is now '' S. agrarium'' :''S. chloranthum'' as described by C.P.J.

Michel Félix Dunal
Michel Félix Dunal (24 October 1789 in Montpellier – 29 July 1856 in Montpellier) was a French botanist. He was a professor of botany in Montpellier, France. He held the chair of natural history at the University of Montpellier from 1816 until his death in 1856. The Solanaceae, Solanaceous plant genus ''Dunalia'' is named after him, as is the green algae genus ''Dunaliella''. He is especially known for his work with the genus ''Solanum'', and published an important work on the genus; ''Solanorum generumque affinium Synopsis seu Solanorum Historiae, editionis secundae summarium ad characteres differentiales redactum, seriem naturalem, habitationes stationesque specierum breviter indicans'', Montpellier, 1816. For the work ''Prodromus systematis naturalis regni vegetabilis'' by Augustin de Candolle and his son, Alphonse Pyrame de Candolle, he contributed to Volume I of 1824 "Cistineae" (modern Cistaceae), to Volume VII, No. 2 of 1839 "Vaccinieae", and to Volume XIII No. 1 of 1 ...

Solanum Aculeatissimum
''Solanum aculeatissimum'', known as Dutch eggplant, and love-apple, is a weedy shrub that bears small, 2–3 cm pale yellow fruit following white flowers with characteristic ''Solanum'' yellow stamens. Origin and range Where ''S. aculeatissimum'' is native to has yet to be conclusively determined. Despite its common name suggesting a South-Asian origin, however, the plant's origin is most likely either Africa or South America; while specimens have been identified in Asia, it is rare there and believed to be the result of accidental or deliberate introduction. It is closely related to other ''Solanum'' species native to both sub-Saharan Africa and Central America. Africa was the first continent in which ''S. aculeatissimum'' was documented. Scottish-born botanist Francis Masson found the plant near the Cape of Good Hope either during the years 1772–1774, or during a subsequent expedition when he remained in southern Africa from 1786 until 1795. In South America, the plant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States National Agricultural Library
The United States National Agricultural Library (NAL) is one of the world's largest agricultural research libraries, and serves as a national library of the United States and as the library of the United States Department of Agriculture. Located in Beltsville, Maryland, it is one of five national libraries of the United States (along with the Library of Congress, the National Library of Medicine, the National Transportation Library, and the National Library of Education).

Biological Pest Control
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insects play an important part in limiting the densities of potential pests. Biological control agents such as these include predators, parasitoids, pathogens, and com ...

Triclopyr
Triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) is an organic compound in the pyridine group that is used as a systemic foliar herbicide and fungicide. History Triclopyr triethylammonium (TEA) was first registered in 1979 in the United States for use as an herbicide in non-crop areas and forestry to control broadleaf weeds and woody plants. A year later, in 1980, a formulation containing triclopyr butoxyethyl ester (BEE) was registered for similar applications. Both formulations expanded their usage to turf sites in 1984, and in 1985, triclopyr BEE was specifically registered for use on rangeland and permanent grass pastures. In 1995, the triclopyr TEA formulation received registration for use on rice crops to manage broadleaf weed species. Uses Triclopyr is a systemic herbicide and is selectively used to control dicotyledonous (broadleaf) weeds and woody plants while leaving monocotyledonous plants (such as grasses, bulbs, and conifers) largely unaffected. It is clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypress Head
A cypress dome is a type of freshwater forested wetland, or a swamp, found in the southeastern part of the United States. They are dominated by the ''Taxodium spp''., either the bald cypress (''Taxodium distichum''), or pond cypress (''Taxodium ascendens''). The name comes from the dome-like shape of treetops, formed by smaller trees growing on the edge where the water is shallow while taller trees grow at the center in deeper water. They usually appear as circular, but if the center is too deep, they form a “doughnut” shape when viewed from above. Cypress domes are characteristically small compared to other swamps, however they can occur at a range of sizes, dependent on the depth. Cypress domes form when pond cypress grow in shallow standing water. The ground level in the center of the dome may be several inches to a few feet lower than at the edge of the dome, but tree growth is more vigorous at the center of the dome. Thus, the treetops are higher at the center than at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammock (ecology)
Hammock is a term used in the southeastern United States for stands of trees, usually hardwood, that form an ecological island in a contrasting ecosystem. Hammocks grow on elevated areas, often just a few inches high, surrounded by wetlands that are too wet to support them. The term ''hammock'' is also applied to stands of hardwood trees growing on slopes between wetlands and drier uplands supporting a mixed or coniferous forest. Types of hammocks found in the United States include tropical hardwood hammocks, temperate hardwood hammocks, and maritime or coastal hammocks. Hammocks are also often classified as hydric (wet soil), mesic (moist soil) or xeric (dry soil). The types are not exclusive, but often grade into each other. Unlike many ecosystems of the coastal plain of the southeastern United States, hammocks are not tolerant of fire. Hammocks tend to occur in locations where fire is not common, or where there is some protection from fire in neighboring ecosystems. Hammocks ...

Giant Hogweed
''Heracleum mantegazzianum'', commonly known as giant hogweed, is a monocarpic perennial herbaceous plant in the carrot family Apiaceae. ''H. mantegazzianum'' is also known as cartwheel-flower, giant cow parsley, giant cow parsnip, or hogsbane. In New Zealand, it is also sometimes called wild parsnip (not to be confused with '' Pastinaca sativa'') or wild rhubarb. Giant hogweed is native to the western Caucasus region of Eurasia. It was introduced to Britain as an ornamental plant in the 19th century, and has also spread to other areas in Western Europe, the United States, and Canada. Its close relatives, Sosnowsky's hogweed and Persian hogweed, have similarly spread to other parts of Europe. The sap of giant hogweed is phototoxic and causes phytophotodermatitis in humans, resulting in blisters and scars. These serious reactions are due to the furanocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant. Consequently, the jurisdictions of many ...

Plant Pest
A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; Wolf, wolves, snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include Housefly, houseflies, which land on and contaminate food; Beetle, beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats and cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noxious Weed
A noxious weed, harmful weed or injurious weed is a weed that has been designated by an agricultural or other governing authority as a plant that is harmful to agricultural or horticultural crops, natural habitats or ecosystems, or humans or livestock. Most noxious weeds have been introduced species, introduced into an ecosystem by ignorance, mismanagement, or accident. Some noxious weeds are native, though many localities define them as necessarily being non-native. Typically they are plants that grow aggressively, multiply quickly without natural controls (native herbivores, soil chemistry, etc.), and display adverse effects through contact or ingestion. Noxious weeds are a large problem in many parts of the world, greatly affecting areas of agriculture, forestry, forest management, nature reserves, regional park, parks and other open space. Many noxious weeds have come to new regions and countries through contaminated shipments of feed and crop seeds or were intentionally introd ...
