Chlorphoxime is an insecticide used as crop protection active ingredient.^[1] Chlorphoxime is also a cholinesterase inhibitor and a neurotoxin.^[2]

Properties

A study was conducted to investigate the effect of chlorophoxime for the control of fleas in kangaroo rats and hispid cotton rats. Chlorphoxime was found to be effective.^[3]

In another study, the efficacy of some insecticides was investigated on certain storage pests. While phoxim, bioresmethrin and fenitrothion showed strong activity against the red-brown rice mealybug, the insecticidal activity of chlorphoxim and permethrin was low.^[4]

Production

The synthesis of chlorophoxime is described in the following reaction sequence:^[1]

Trade names

A crop protection product containing the active ingredient chlorophoxime is marketed under the trade name Baythion.^[1]

Approval

No plant protection products containing chlorophoxime are approved in the European Union or Switzerland.^[5]
