Sodium tetrathiocarbonate

Sodium tetrathiocarbonate is a specialized active ingredient belonging to the thiocarbonate chemical class. In modern agriculture, it serves primarily as a soil fumigant, utilized to sanitize the soil environment by eliminating harmful pests and pathogens before or during the crop cycle.

The mechanism of action involves the release of carbon disulfide upon the decomposition of the substance in moist soil. This active gas acts as a potent biocide, penetrating soil particles and effectively targeting the respiratory and metabolic systems of nematodes, soil-dwelling insects, and various pathogenic fungi residing in the root zone.

This compound is specifically labeled for use against a wide range of soil-borne threats. It is highly effective in treating land designated for high-value vegetable production, fruit trees, and nursery stock. By reducing the pressure from root-knot nematodes and soil-borne fungal rots, it helps ensure a healthier and more vigorous plant development.

Application procedures require precise technical control. It is typically applied through irrigation systems (chemigation) or via subsurface injection. Factors such as soil texture, temperature, and moisture levels must be carefully managed to ensure uniform dispersion of the gas throughout the soil profile for maximum efficacy.

Strict safety measures must be followed due to the hazardous nature of the volatile breakdown products. Protective clothing, gloves, and respirators are required during handling to prevent skin contact and inhalation. Users must adhere strictly to established re-entry intervals and pre-plant waiting periods to ensure that all fumigant residues have dissipated before crops are introduced to the soil.
