Phosmet is a phthalimide-derived, non-systemic, organophosphate insecticide used on plants and animals. It is mainly used on apple trees for control of coddling moth, though it is also used on a wide range of fruit crops, ornamentals, and vines for the control of aphids, suckers, mites, and fruit flies.[2]

[edit] Safety
Phosmet is on the US Emergency Planning List of Extremely Hazardous Substances. It is highly toxic to bees.[2]
Mark Purdey has made the controversial suggestion that phosmet may have played a key role in the epidemic of bovine spongiform encephalopathy (BSE).[3]
[edit] In popular culture
- In the medical drama House, the episode "Poison" features two teenage boys who are diagnosed with phosmet poisoning.
