Prothiofos

Prothiofos, a colorless liquid, is an organophosphorous insecticide developed by Nihon Bayer Agrochem. It is effective against lepidopteran pests and aphids.

Prothiofos (RS)-(O-2,4-dichlorophenyl O-ethyl S-propyl phosphorodithioate)

Prothiofos isn't a medication, it's actually an insecticide. Here's a breakdown of what it is:

  • Type: Organic thiophosphate insecticide [PubChem]
  • Function: Kills insects by inhibiting acetylcholinesterase, an enzyme critical for their nervous system function [PubChem].
  • Properties:
    • Non-systemic - meaning it stays on the plant surface and doesn't travel inside [RELIABLE FAST ACTION WITH RESIDUAL CONTROL]
    • Relatively low toxicity for mammals compared to some other insecticides [RELIABLE FAST ACTION WITH RESIDUAL CONTROL]
    • Acts mainly as a stomach poison for insects [RELIABLE FAST ACTION WITH RESIDUAL CONTROL]

Important to note:

  • Prothiofos is a restricted-use pesticide, meaning it can only be applied by certified applicators due to potential hazards.
  • Because it affects the nervous system, exposure to high levels can be harmful to humans as well.
