Sodium Metabisulphite (SMBS)
Sodium Metabisulphite (SMBS)
Sodium Metabisulphite (SMBS, Na₂S₂O₅) is a versatile sulphur-based compound widely used in agriculture for its antimicrobial, antioxidant, and preservative properties. It serves as a source of sulphur, helps in water treatment, soil sterilization, and post-harvest preservation, and plays a vital role in protecting crops and produce from microbial spoilage. Its ability to release sulphur dioxide (SO₂) makes it effective in controlling fungi, bacteria, and pests in agricultural systems.
