What Is Fenitrothion?
Fenitrothion, with the chemical formula C9H12NO5PS, is a pesticide ingredient developed to safeguard crops from various pests such as aphids, stink bugs, and borers. It has been used in formulations like microcapsules, aerosols, and emulsions, often abbreviated as MEP.
Uses of Fenitrothion
This organophosphate pesticide is applied across a broad spectrum of agricultural settings, including rice, fruit trees, and vegetables. Beyond agriculture, fenitrothion finds use in household insecticides and termite control, demonstrating its versatility and effectiveness in pest management.
Principle of Fenitrothion
As an acetylcholinesterase inhibitor, fenitrothion disrupts essential nerve functions in pests, leading to their eradication. This action is achieved through the oxidation of fenitrothion into an oxon, which then inhibits cholinesterase activity critical for nerve transmission.
Types of Fenitrothion
Fenitrothion-based insecticides are differentiated by their active ingredient concentration, offering various application methods such as emulsions and hydrates to cater to different pest control needs.
1. Sumipine Emulsion
An 80% fenitrothion solution particularly effective against tree pests, adaptable to multiple application techniques including aerial sprays.
2. Sumithion Emulsion
A 50% fenitrothion formulation, widely accessible for comprehensive pest control in both agricultural and residential settings.
3. Sumithion Hydrate 40
This 40% powdered form is tailored for fruit tree protection, targeting a range of insects from aphids to stink bugs.
