Product Introduction
Copper Sulphate Pentahydrate (CuSO₄·5H₂O) is a blue crystalline powder or granule containing 24% to 25% copper (Cu). It is widely used as a micronutrient fertilizer to correct copper deficiency in crops and soil. Copper is essential for photosynthesis, respiration, enzyme activity, and lignin synthesis in plants.
This product is also known for its fungicidal properties and is used in formulations like Bordeaux mixture for disease control. It is highly soluble in water, making it suitable for soil application, foliar spraying, and fertilizer blending.
