Malathion is an organophosphate insecticide which acts as an acetylcholinesterase inhibitor. In the USSR , it was known as carbophos , in New Zealand and Australia as maldison and in South Africa as mercaptothion .
malathion) may be sold as technical material (TC - which is mostly AI, but also contains small quantities of, usually non-active, by-products of the manufacturing process; TGAC - "technical grade active constituent" means the same.).
Isomalathion is an impurity found in some batches of malathion. Whereas the structure of malation is, generically, RSP(S)(OCH 3) 2, the connectivity of isomalathion is RSPO(SCH 3)(OCH 3). It arises by heating malathion. Being significantly more toxic to humans than malathion, it has resulted in human poisonings. [1]
Toxicity labels [1] viz; red label, yellow label, blue label and green label are mandatory labels employed on pesticide containers in India identifying the level of toxicity (that is, the toxicity class) of the contained pesticide. [1] [2] [3] The schemes follows from the Insecticides Act of 1968 [1] and the Insecticides Rules of 1971.
Acetylcholine Acetylcholinesterase Acetylcholinesterase inhibition. Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, [1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ...
Pesticide application can artificially select for resistant pests. In this diagram, the first generation happens to have an insect with a heightened resistance to a pesticide (red) After pesticide application, its descendants represent a larger proportion of the population, because sensitive pests (white) have been selectively killed.
The transparency the labels provide could help Americans save money, FCC and White House officials say. Consumer broadband labels will be required for internet providers starting on Wednesday ...
Organophosphate and carbamate insecticides, e.g. malathion and bendiocarb, respectively, are more expensive than DDT per kilogram and are applied at roughly the same dosage. Pyrethroids such as deltamethrin are also more expensive than DDT, but are applied more sparingly (0.02–0.3 g/m 2 vs 1–2 g/m 2 ), so the net cost per house per ...
