A class of organic, phosphorus-containing insecticides which inhibit cholinesterase causing excess nerve activation, paralysis and eventual death; some insecticides in this class with a high phosphorus content (e.g., methyl parathion) may delay cotton crop maturity if applied at an early stage; abbreviated OP.
a class of synthetic, organic pesticides which contain phosphorus, generally have a short residual life and act as nerve poisons on most animals
The organophosphate insecticides are poisons that interrupt nerve conduction. These compounds cause the accumulation of acetylcholine at nerve endings by irreversibly binding with the acetycholinesterase enzyme.
A class of organic pesticides containing phosphorus, which interrupts nerve impulses along the central nervous system leading to convulsions, paralysis, and death.
Pesticides that contain phosphorus; short-lived, but some can be toxic when first applied.
Insecticides that contain phosphorus, carbon, and hydrogen. They are cholinesterase inhibitors; some are highly acutely toxic, but they usually are not persistent in the environment. Parathion is an example of an organophosphate.
A class of insecticides composed of organic radical bound to a phosphorus containing radical. Examples include: Dichlorvos, Trichlorfon, Tetrachlorvinphos and Paraoxon.
These are a type of adulticides that kill insects by shutting down their central nervous system. Organophosphates are divided into groups, and there is some debate as to which are less toxic to humans and the environment in general, but the widespread use of any is often controversial. (See Adulticide).
Synthetic organic pesticides that contain carbon, hydrogen and phosphorous; toxic to humans because they prevent proper transmission of the nerve impulses; a compound with a specific phosphate group which inhibits acetycholinesterase; used in chemical warfare and as an insecticide. Examples include Parathion and Malathion.
