Introduction
- Profenofos was developed by Novartis Crop Protection in 1975. It was then first registered in the United States in 1982. As of 2015, it is not approved in the European Union.
- Profenofos is an organophosphate insecticide. It is a pale yellow to amber liquid with a garlic-like odor.
Physical and chemical properties:
- CAS No: 41198-08-7
- IUPAC: 4-brom-2-clo-1-[ethoxy(propylsulfanyl)phosphoryl]oxybenzen
- Appearance: Light yellow or amber liquid.
- Molecular formular: 373,63 g/mol
- Soluble in almost organic solvents
Mechanism of action
- Similar to other active ingredients of the organophosphate group, the mechanism of action of Profenofos is through inhibition of the enzyme acetylcholinesterase as well as cholinestaza, which inhibits neurotransmitters, thereby causing loss of activity control, and leads to death.
- Profenofos causes acute and chronic neurotoxic reactions that weaken the nervous system of insect pests. The sauna feature causes muscle weakness, loss of control, and paralysis of the respiratory system.
- Main mechanisms of action: contact, toxicity, vaporization, penetration and translocation.
Advantage
- The spectrum of effect is broad so it can kill many objects
- It has the ability to quickly penetrate deeply and be able to move to the underside of leaves.
- Avoid washing away when it rains.
Disadvantage
- Highly toxic to humans and the environment
- Affects natural enemies
- Odor is unpleasant

- Leaf rollers and stem borers on rice plants
- Army worms and army worms on cotton plants
- Caterpillars and bean army worms on bean plants

- Sucking insects:
- Thrips, panicle spiders, green leafhoppers, white-backed planthoppers, and brown planthoppers on rice plants
