Used as corrosion inhibitor in hydrocracking and oil drilling fluids.As reducing agent in textile,dyes ,organic chemicals.

Sodium polysulphide solution is a reddish-brown to dark amber alkaline liquid containing a mixture of sodium sulfide and elemental sulfur dissolved in water. It is characterized by a strong odor of hydrogen sulfide (H₂S) and has high reducing and alkaline properties.

In agriculture, it is used primarily as a fungicide, insecticide, and soil amendment, while in industry it serves as a chemical intermediate, depilatory, and flotation agent.

Typical industrial/agricultural grades contain:

• Active sodium polysulfide: 20–50% by weight

When applied to plants or soil:

• The polysulfides release elemental sulfur and hydrogen sulfide upon hydrolysis.

• These compounds act as contact fungicides and acaricides, disrupting respiration and enzyme systems in fungal spores, mites, and insects.

• Also provides sulfur nutrition to crops and can reduce certain soilborne pathogens.

A. Agricultural Uses

• Fungicide/insecticide: Control of powdery mildew, mites, scale insects, and certain fungal diseases on fruit trees, vines, and ornamentals.

• Dormant spray: Applied during the dormant season on deciduous trees to kill overwintering pests.

• Soil treatment: Occasionally used to suppress fungal or nematode activity.

B. Industrial Uses

• Leather processing: Hair removal and de-liming.

• Pulp & paper: Kraft pulping additive.

• Ore flotation: Sulfide mineral depressant.

• Chemical manufacture: Intermediate for sulfur dyes and thiochemicals.

• Corrosive to skin, eyes, and metals.

• Reacts with acids to release toxic hydrogen sulfide gas.

• Use only with proper PPE (gloves, goggles, face shield).

• Store in tightly sealed, corrosion-resistant containers away from acids and oxidizers.

• Ensure adequate ventilation during mixing or spraying.
