Methamidophos
Methamidophos, trade name "Monitor," is an organophosphate insecticide. Crops grown with the use of methamidophos include potatoes and some Latin American rice. Many nations have used methamidophos on crops, including developed nations such as Spain, United States, Japan, and Australia. Due to its toxicity, the use of pesticides that contain methamidophos is currently being phased out in Brazil. In 2009, all uses in the United States were voluntarily canceled. Toxicity rates of 21 and 16 mg/kg for male and female rats, respectively. 10–30 mg/kg in rabbits, and dermal LD50 of 50 mg/kg in rats. It is rapidly absorbed through the stomach, lungs, and skin in humans, and eliminated primarily through urine. It is a cholinesterase inhibitor. Breakdown in soil is 6.1 days in sand, 309 days in water at pH 5.0, 27 days at pH 7.0, and 3 days at pH 9.0. Sunlight accelerates breakdown. It is uptaken through roots and leaves of plants. It is classified as a WHO Toxicit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acephate
Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. It is used primarily for control of aphids, including resistant species, in vegetables (e.g. potatoes, carrots, greenhouse tomatoes, and lettuce) and in horticulture (e.g. on roses and greenhouse ornamentals). It also controls leaf miners, caterpillars, sawflies, thrips, and spider mites in the previously stated crops as well as turf, and forestry. By direct application to mounds, it is effective in destroying imported fire ants. Acephate is sold as a soluble powder, as emulsifiable concentrates, as pressurized aerosol, and in tree injection systems and granular formulations. As of 2012, the EPA no longer allows the usage of acephate on green beans grown in the United States. Toxicology It is considered non- phytotoxic on many crop plants. Acephate and its primary metabolite, methamidophos, are toxic to ''Heliothis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organophosphate
In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure , a central phosphate molecule with alkyl or aromatic substituents. They can be considered as esters of phosphoric acid. Organophosphates are best known for their use as pesticides. Like most functional groups, organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, nerve agents and flame retardants. OPEs have been widely used in various products as flame retardants, plasticizers, and performance additives to engine oil. The low cost of production and compatibility to diverse polymers made OPEs to be widely used in industry including textile, furniture, electronics as plasticizers and flame retardants. These compounds are added to the final product physically rather than by chemical bond. Due to this, OPEs leak in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acetylcholinesterase Inhibitors
Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, inhibit the enzyme acetylcholinesterase from Hydrolysis, breaking down the neurotransmitter acetylcholine into choline and acetate, thereby increasing both the level and duration of action of acetylcholine in the central nervous system, Autonomic ganglion, autonomic ganglia and neuromuscular junctions, which are rich in acetylcholine receptors. Acetylcholinesterase inhibitors are one of two types of cholinesterase inhibitors; the other being Butyrylcholinesterase#Inhibitors, butyryl-cholinesterase inhibitors. Acetylcholinesterase is the primary member of the cholinesterase, cholinesterase enzyme family. Acetylcholinesterase inhibitors are classified as reversible, irreversible, or quasi-irreversible (also called pseudo-irreversible). Mechanism of action Organophosphates Organophosphates like TEPP, tetraethyl pyrophosphate (TEPP) and sarin inhibit cholinesterases, enzymes that hydrolyze the ...

Gyoza
''Jiaozi'' or Gyoza (; ) are a type of Chinese dumpling. ''Jiaozi'' typically consist of a ground meat or vegetable filling wrapped into a thinly rolled piece of dough, which is then sealed by pressing the edges together. ''Jiaozi'' can be boiled (), steamed (), pan-fried (), or deep-fried (), and are traditionally served with a black vinegar and sesame oil dip. They can also be served in a soup (). ''Jiaozi'' have great cultural significance within China. ''Jiaozi'' are one of the major dishes eaten during the Chinese New Year throughout northern China and eaten all year round in the Northern and southern China, northern provinces. Their resemblance to the gold and silver ingots (sycee) used in Imperial China has meant that they symbolize wealth and good fortune. A Japanese variety of ''jiaozi'' is referred to as gyōza; the ''jiaozi'' was introduced to Japan by returning Japanese soldiers during the Second Sino-Japanese War, Japanese invasion and colonization of China.

Toxicity Class
Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization. It addresses the acute toxicity of agents such as soil fumigants, fungicides, herbicides, insecticides, miticides, molluscicides, nematicides, or rodenticides. General considerations Assignment to a toxicity class is based typically on results of acute toxicity studies such as the determination of values in animal experiments, notably rodents, via oral, inhaled, or external application. The experimental design measures the acute death rate of an agent. The toxicity class generally does not address issues of other potential harm of the agent, such as bioaccumulation, issues of carcinogenicity, teratogenicity, mutagenic effects, or the impact on reproduction. Regulating agencies may require that packaging of the agent be labeled with a signal word, a specific warning label to indicate the level of toxicity. By ...

Insecticide
Insecticides are pesticides used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans. Acaricides, which kill mites and ticks, are not strictly insecticides, but are usually classified together with insecticides. Some insecticides (including common bug sprays) are effective against other non-insect arthropods as well, such as scorpions, spiders, etc. Insecticides are distinct from insect repellents, which repel but do not kill. Sales In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less th ...
