Phytophthora Tentaculata
''Phytophthora tentaculata'' is a plant pathogen that causes root and stalk rot. It was first isolated in 1993 in a nursery in Germany infecting ''Chrysanthemum'', ''Verbena'', and ''Delphinium ajacis''. It has since been found infecting a ''Verbena'' in Majorca, Spain in June 2001 but was thought to be restricted to nurseries in Germany and the Netherlands. Other species have since been found to be infected, ''Santolina chamaecyparissus'' (Lavender cotton) in Spain in 2004, ''Gerbera jamesonii'' in Italy 2006, and '' Aucklandia lappa'' in China in 2008. References tentaculata Tentaculata is a class of comb jellies. The common feature of this class is a pair of long, feathery, contractile tentacles, which can be retracted into specialised ciliated sheaths. In some species, the primary tentacles are reduced and they h ... Water mould plant pathogens and diseases Ornamental plant pathogens and diseases Species described in 1993 {{plant-disease-stub ...

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ...

Water Mould Plant Pathogens And Diseases
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...

Phytophthora
''Phytophthora'' (from Greek language, Greek (''phytón''), "plant" and (), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental degradation, environmental damage in natural ecosystems. As well as impacting large scale agriculture, ''Phytophthora'' is a nuisance to garden and indoor plant hobbyists as well as bonsai artists. The cell wall of ''Phytophthora'' is made up of cellulose. The genus was first described by Anton de Bary, Heinrich Anton de Bary in 1875. Approximately 170 species have been described, although 100–500 undiscovered ''Phytophthora'' species are estimated to exist. Pathogenicity ''Phytophthora'' species, spp. are mostly pathogens of dicotyledons, and many are relatively host-specific parasites. ''Phytophthora cinnamomi'', though, infects thousands of species ranging from club mosses, ferns, cycads, coni ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Aucklandia Lappa
''Dolomiaea costus'', formerly known as ''Saussurea costus'', commonly known as costus, Indian costus, kuth, or putchuk, is a species of thistle in the genus '' Dolomiaea'' native to South Asia and China. Rishi (Hindu) mystics of Kashmir especially ate this plant. Essential oils extracted from the root have been used in traditional medicine and in perfumes since ancient times. Costus is the root of this plant. The root of the plant is the key part used for medicinal or homeopathic purposes.Davidson, Tish. "Aucklandia." ''The Gale Encyclopedia of Alternative Medicine'', edited by Laurie J. Fundukian, 4th ed., vol. 1, Gale, 2014, pp. 197-198. ''Gale Virtual Reference Library'', Accessed 20 Nov. 2017.

Gerbera Jamesonii
''Gerbera jamesonii'' is a species of flowering plant in the genus ''Gerbera'' belonging to the basal Mutisieae tribe within the large Asteraceae (or Compositae) family. It is indigenous to South Eastern Africa and commonly known as the Barberton daisy,Siyabona Africa http://www.krugerpark.co.za/africa_barberton_daisy.html the Transvaal daisy, and as Barbertonse madeliefie or Rooigousblom in Afrikaans. It was the first species of Gerbera to be the subject of a scientific description, studied by J. D. Hooker in ''Curtis's Botanical Magazine'' in 1889. Etymology The genus was named in honour of German botanist and medical doctor Traugott Gerber (1710 — 1743). The ''Gerbera jamesonii'' was named in honour of Robert Jameson, who collected the plant near Barberton. The species epithet was proposed by the prominent South African botanist Harry Bolus, but first published by Richard Wills Adlam in 1888, so should be ascribed to him. Description ''Gerbera jamesonii'' is a tufted pe ...

Root Rot
Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with poor drainage. The leaves of plants experiencing root rot often yellow and die, and if allowed to continue, the condition can be fatal. To avoid root rot, it is best to only water plants when the soil becomes dry, and to put the plant in a well-drained pot. Using a dense potting media such as one dug up from outdoors can also cause root rot. Plants from different environments have different tolerances for soil moisture: plants evolved for desert conditions will experience root rot at lower moisture levels than plants evolved for tropical conditions. In both indoor and outdoor plants, it can be lethal and there is no effective treatment, though ...
