Uses

Used in Agricultural Industry:
Tetradifon is used as an acaricide and ovicide for controlling pests on deciduous fruits, citrus, cotton, and other crops. It helps in protecting these crops from damage caused by mites and insects, ensuring better yield and quality of the produce.

Safety Profile

Moderately toxic by ingestion. Mildly toxic by slun contact. An experimental teratogen. Used to control worms in crops. When heated to decomposition it emits highly toxic fumes of Cland SOx.
