== Introduction and history == Carbophenothion is a highly toxic organophosphate insecticide and acaricide. Organophosphates are acetylcholinesterase inhibitors and disrupt the signal transduction at the cholinergic synapse. It is classified as Restricted Use Pesticide (RUP) by the Environmental Protection Agency (EPA). Carbophenothion is used in different brands like Trithion. This pesticide contains 80% carbophenothion as its only active ingredient. Because of the widespread use of those organophosphates in the nineties in the US, it was the most common cause of agricultural poisonings.
