Phosmet

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.

Safety
Phosmet is on the US Emergency Planning List of Extremely Hazardous Substances. It is highly toxic to bees.

Mark Purdey has made the controversial suggestion that phosmet may have played a key role in the epidemic of bovine spongiform encephalopathy (BSE).
