Application

Zinc Dimethyldithiocarbamate is a versatile chemical compound primarily utilized as a rubber vulcanization accelerator and a broad-spectrum fungicide and animal repellent. As a zinc salt of dimethyldithiocarbamic acid, it plays a critical role in agricultural settings, providing protection against a variety of fungal diseases across numerous crops, including stone fruits, pome fruits, nut crops, vegetables, and commercially grown ornamentals. Additionally, it serves as an effective soil and seed treatment and is formulated for outdoor foliar applications as a bird and rabbit repellent. Its qualities as a fungicide, microbiocide, and repellant make it a valuable tool for farmers and industries in the U.S. and EU. Despite being practically insoluble in water, its solubility in substances like acetone, carbon disulfide, and other chemicals expands its applicability across different uses.
