Description:

WARNING: This product is for research use only, not for human or veterinary use.

Phosmet oxon is a toxic metabolite of phosmet, a phthalimide-derived, non-systemic, organophosphate insecticide used on plants and animals. It is mainly used on apple trees for control of codling 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.
