- Essential Micronutrient Supply: It corrects copper deficiencies, which are common in sandy, acidic, or peaty soils, supporting crucial physiological processes like photosynthesis, enzyme regulation, and protein metabolism.
- Effective Fungicide & Bactericide: It acts as a powerful preventative agent against fungal diseases (e.g., mildew, blight, leaf spots) and bacterial pathogens by breaking down their proteins.
- High Water Solubility: Copper sulphate dissolves readily in water, making it suitable for both foliar application and soil drenching.
- Bordeaux Mixture Component: It is a key ingredient in the "Bordeaux mixture" (mixed with lime and water), a traditional, highly effective, and widely used fungicide.
- Soil Amendment & Stimulant: It enhances lignin formation in plants, strengthening tissues and increasing resistance to diseases and environmental stress.
- Long Residual Effect: Soil applications can have a lasting positive effect for over ten years.
- Correction of Copper Deficiency: It rectifies deficiencies (e.g., in peaty/acidic soils) that cause stunted growth, chlorosis, and reduced flowering.
- Enhanced Disease Resistance & Control: It acts as a fungicide and bactericide, controlling diseases like powdery mildew, downy mildew, leaf spots, and blight. It strengthens cell walls, making plants more resilient.
- Boosts Growth and Metabolism: Copper is essential for enzyme activation, protein synthesis, and photosynthesis, ensuring efficient chlorophyll production.
- Improved Reproductive Success: Essential for the development of flowers, seeds, and fruits, directly increasing yield.
- Soil and Environmental Management: It helps maintain soil pH, controls snails and slugs, and is used to remove algae.
- Nutritional Support for Livestock: It can be applied to pastures to improve soil fertility and treat copper deficiency in grazing animals.
