Fensulfothion (DMSP), a yellow-brown liquid, is an organophosphorous nematicide that is applied in the soil for control of cyst nematode, root-knob nematode and the like.
Fensulfothion O,O-diethyl O-4-methylsulfinylphenyl phosphorothioate
Fensulfothion is an insecticide and nematicide that was previously used on a variety of crops. It is an organophosphate compound, which means it works by inhibiting the enzyme acetylcholinesterase. This enzyme is essential for normal nervous system function, and inhibition of acetylcholinesterase can lead to a variety of serious health problems, including:
- Muscle weakness
- Nausea and vomiting
- Diarrhea
- Dizziness
- Headache
- Confusion
- Seizures
- Coma
- Respiratory failure
Fensulfothion is a highly toxic substance and can be harmful if inhaled, swallowed, or absorbed through the skin. It is also a suspected carcinogen. Due to its dangers, fensulfothion is now banned in many countries, including the United States.
If you or someone you know has been exposed to fensulfothion, it is important to seek medical attention immediately. Treatment for fensulfothion poisoning may include:
- Atropine to relieve muscle weakness
- Pralidoxime to reactivate acetylcholinesterase
- Supportive care, such as oxygen therapy and mechanical ventilation
