Desmodium canadense is a species of flowering plant in the legume family, Fabaceae. It is native to eastern North America. Its common names include showy tick-trefoil, Canadian tick-trefoil, [1] and Canada tickclover. [2]
The plant is a perennial herb and grows in woods, prairies, and disturbed habitat, such as roadsides. It is cultivated as an ornamental plant. It is a larval host plant for butterflies such as the eastern tailed-blue, silver-spotted skipper, and hoary edge. The plant attracts butterflies and hummingbirds. [3] Flowers are pea-shaped, pink to purple in color, and bloom between July and September. [4]
Desmodium canadense is being investigated as a possible source of bean pod mottle virus in soybean plants. As a carrier of the virus, it may be passing it to the bean leaf beetle, which is passing it in turn to soybean crops. [5] This virus causes severe systemic mottling and mild leaf puckering. [6] This can reduce seed size and pod set, which causes a decrease in crop yields. [7]
Legumes are plants in the family Fabaceae, or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption, but also as livestock forage and silage, and as soil-enhancing green manure. Well-known legumes include beans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces on two sides.
The mung bean or green gram is a plant species in the legume family. The mung bean is mainly cultivated in East, Southeast and South Asia. It is used as an ingredient in both savoury and sweet dishes.
Soybean rust is a disease that affects soybeans and other legumes. It is caused by two types of fungi, Phakopsora pachyrhizi, commonly known as Asian soybean rust, and Phakopsora meibomiae, commonly known as New World soybean rust. P. meibomiae is the weaker pathogen of the two and generally does not cause widespread problems. The disease has been reported across Asia, Australia, Africa, South America and the United States.
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. Species are distributed widely – from Quebec to northern Argentina in the Americas, across northern and southern tropical Africa, in the southern Arabian Peninsula, in Myanmar and Thailand, New Guinea, and northern and eastern Australia.
Begomovirus is a genus of viruses, in the family Geminiviridae. They are plant viruses that as a group have a very wide host range, infecting dicotyledonous plants. Worldwide they are responsible for a considerable amount of economic damage to many important crops such as tomatoes, beans, squash, cassava and cotton. There are 445 species in this genus.
The Mexican bean beetle is a species of lady beetle that can be an agricultural pest. It is one of the few North American lady beetles that feed on plants rather than other insects. It is found throughout Mexico and the eastern United States, and is abundant in the wetter and more heavily irrigated areas west of the Rocky Mountains. It does not tolerate extremely dry areas.
Phialophora gregata is a Deuteromycete fungus that is a plant pathogen which causes the disease commonly known as brown stem rot of soybean. P. gregata does not produce survival structures, but has the ability to overwinter as mycelium in decaying soybean residue.
Bean pod mottle virus, or BPMV, is a species of plant pathogenic virus in the family Secoviridae. It is known to infect soybean crops.
Peanut mottle virus(PeMoV) is a pathogenic plant virus of the family Potyviridae. As with other members of this virus family, PeMoV is a flexuous filamentous virus with particles 740–750 nm long. It is transmitted by several species of aphids and by mechanical inoculation. It was first given its name in 1965 when it was isolated from peanuts (Arachis hypogaea) in Georgia, United States. The virus was found to be seed transmitted in its host.
Soybean mosaic virus (SMV) is a member of the plant virus genus Potyvirus. It infects mainly plants belonging to the family Fabaceae but has also been found infecting other economically important crops. SMV is the cause of soybean mosaic disease that occurs in all the soybean production areas of the world. Soybean is one of the most important sources of edible oil and proteins and pathogenic infections are responsible for annual yield losses of about $4 billion in the United States. Among these pathogens, SMV is the most important and prevalent viral pathogen in soybean production worldwide. It causes yield reductions of about 8% to 35%, but losses as high as 94% have been reported.
Thorybes bathyllus, the southern cloudywing, is a North American butterfly in the family Hesperiidae. Southern cloudywings can be difficult to identify because of individual variation and confusing seasonal forms. In the south, where it has two broods per year, two seasonal forms occur. Spring forms are usually lightly marked and resemble confused cloudywings. Summer forms tend to be more boldly marked, by comparison, making identification easier. However, summer confused cloudywings are also strongly patterned, which makes identifying them more difficult. Their rapid flight is very erratic, though it is closer to the ground than in some of its close relatives.
Organic beans are produced and processed without the use of synthetic fertilizers and pesticides. In 2008, over 2,600,000 acres (11,000 km2) of cropland were certified organic in the United States. Dry beans, snap beans, and soybeans were grown on 16,000 acres (65 km2), 5,200 acres (21 km2), and 98,000 acres (400 km2), respectively.
Cerotoma trifurcata is a species of beetle in the Chrysomelidae family that can be found in the Eastern and West United States.
Epicauta vittata is a species of beetle in the family Meloidae, the blister beetles. It is native to eastern North America, including eastern Canada and the eastern United States. It is known commonly as the striped blister beetle and the old-fashioned potato beetle. It is known as an agricultural pest.
Desmodium illinoense, the Illinois ticktrefoil, is a flowering plant in the bean family (Fabaceae), native to the central United States and Ontario, Canada. Illinois ticktrefoil grows in sunny places, such as prairies and oak savannas of the Great Plains and Great Lakes regions.
Desmodium glabellum is a species of flowering plant in the legume family Fabaceae. It is native to the eastern and central United States. It is commonly called Dillenius' tick-trefoil in honor of Johann Dillenius, a British botanist of German birth. It is also known as the tall tick-trefoil.
Said Amin (Gabe) Ghabrial was an Egyptian-American plant pathologist, known for his work on mycoviruses – viruses of fungi – and particularly their effects on the virulence of plant-pathogenic fungi. He also researched bean pod mottle virus, an economically important soybean disease. He was professor of plant pathology at the University of Kentucky (1986–2014).
