Used as a fungicide in agriculture, particularly in vineyards, orchards, and for crops like grapes, oranges, and potatoes to protect against fungal diseases such as downy mildew, rust, and black mold. It is also employed in the formulation of wood preservatives to prevent decay and insect damage, and in paints and coatings to provide antifungal and antibacterial properties. In chemical synthesis, it serves as a precursor for other copper compounds and catalysts. Additionally, cupric hydroxide finds use in the textile industry for dyeing and printing processes, where it helps in fixing colors on fabrics, and in wastewater treatment to remove heavy metals and certain toxins.
