Tridemorph
Tridemorph is a fungicide used to control ''Erysiphe graminis''. It was developed by BASF in the 1960s who use the trade name Calixin. The World Health Organization has categorized it as a Class II "moderately hazardous" pesticide because it is believed harmful if swallowed and can cause irritation to skin and eyes. One theory for the cause of the Hollinwell incident The Hollinwell incident refers to an unexplained event in July 1980 when around 300 children suffered fainting attacks, nausea and other symptoms. The incident happened at the Hollinwell Showground in Kirkby-in-Ashfield, in Nottinghamshire, England ... is that it might have been caused by inhalation of tridemorph.

Fungicide
Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upwardly. Most fungicides that can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erysiphe Graminis
''Blumeria graminis'' (commonly called barley powdery mildew or corn mildew) is a fungus that causes powdery mildew on grasses, including cereals. It is the only species in the genus ''Blumeria''. It has also been called ''Erysiphe graminis'' and (by its anamorph) ''Oidium monilioides'' or ''Oidium tritici''. Systematics Previously ''B. graminis'' was included within the genus ''Erysiphe'', but molecular studies have placed it into a clade of its own. Thus since 1975, the species ''graminis'' was moved into the new taxa ''Blumeria'' of which it is the only species. ''Blumeria'' differs from ''Erysiphe'' in its digitate haustoria and in details of the conidial wall. As well ''Blumeria'' is considered to be phylogenetically distinct from ''Erisiphe'' as it is a plant pathogen that hosts solely on the true grasses of ''Poaceae. '' Eight special forms or ''formae speciales'' (ff.spp.) of ''B. graminis'' have been distinguished, each of which is parasitic on a particular genus of gras ...

World Health Organization
The World Health Organization (WHO) is a specialized agency of the United Nations responsible for international public health. The WHO Constitution states its main objective as "the attainment by all peoples of the highest possible level of health". Headquartered in Geneva, Switzerland, it has six regional offices and 150 field offices worldwide. The WHO was established on 7 April 1948. The first meeting of the World Health Assembly (WHA), the agency's governing body, took place on 24 July of that year. The WHO incorporated the assets, personnel, and duties of the League of Nations' Health Organization and the , including the International Classification of Diseases (ICD). Its work began in earnest in 1951 after a significant infusion of financial and technical resources. The WHO's mandate seeks and includes: working worldwide to promote health, keeping the world safe, and serve the vulnerable. It advocates that a billion more people should have: universal health care coverag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticide
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide. The most common of these are herbicides which account for approximately 80% of all pesticide use. Most pesticides are intended to serve as plant protection products (also known as crop protection products), which in general, protect plants from weeds, fungi, or insects. As an example, the fungus ''Alternaria solani'' is used to combat the aquatic weed ''Salvinia''. In general, a pesticide is a chemical (such as carbamate) or biological agent (such as a virus, bacterium, or fungus) that deters, incapacitates, kills, or otherwise discourages pests. Target pests can include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms), and microbes that destroy property, cause nuisance, or spread disease, or a ...

Hollinwell Incident
The Hollinwell incident refers to an unexplained event in July 1980 when around 300 children suffered fainting attacks, nausea and other symptoms. The incident happened at the Hollinwell Showground in Kirkby-in-Ashfield, in Nottinghamshire, England, and the exact cause has never been determined. The two leading theories relate to mass hysteria and the use of pesticides in nearby fields. Background In 1980, the Hollinwell Show, an annual event at the Hollinwell Showground near Kirkby-in-Ashfield, took place on Sunday 13 July. As part of the event the Forest League of Juvenile Jazz Bands decided to hold a charity show, creating a Junior Brass and Marching Band competition, with entrants coming from across the East Midlands. Around 500 children from 11 marching bands were in attendance, many of them brought-in by coaches from up to away. With the show scheduled to begin at 9am, many of the children were tired from their journeys and nervous about performing. The incident At around 1 ...
