Used as a fungicide in agricultural applications, particularly in vineyards and orchards to control fungal diseases such as powdery mildew and downy mildew. It forms part of copper-based pesticide formulations due to its ability to release copper ions, which disrupt enzyme activity in fungi. Also employed in some industrial settings as a biocide to prevent microbial growth in water systems and coatings. Its dual oxygen and sulfur coordination enhances stability and prolongs antimicrobial activity.
