It was patented and introduced in the 1950s by American Cyanamid. Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, an enzyme essential for central nervous system function.
It acts both by contact and through ingestion.
It is readily absorbed and distributed throughout plant tissues, and is degraded relatively rapidly.
enzymes involved in transmitting nerve impulses. Chemically, it is an organophosphate.
Like all organophosphates it is related to the nerve gases and is among the
most toxic of all pesticides to vertebrates, including humans.
As a systemic, dimethoate is taken up into the roots of plants and translocated to aboveground parts,
where it is toxic to any sucking insect feeding on the plant juices
Caterpillars and other chewing pests are not killed by dimethoate because not enough juice-containing
tissue is ingested to be effective.
