Copper Sulfate Pentahydrate (CuSO₄·5H₂O) is a cornerstone product in sustainable agriculture, serving the dual critical roles of an essential plant nutrient and a trusted, broad-spectrum fungicide. Our high-purity, fully soluble crystals provide a reliable solution for correcting copper deficiencies and protecting crops from damaging fungal and bacterial diseases.

Core Benefits: Two Problems, One Solution

1. Corrects Copper Deficiency for Optimal Plant Health
Copper is a vital catalyst for numerous plant enzymes and processes. Its application corrects deficiency symptoms and enhances:

• Chlorophyll Synthesis & Photosynthesis: Essential for energy production and vigorous growth.
• Lignin Formation: Strengthens cell walls, improving stem strength and resistance to lodging.
• Reproductive Development: Crucial for pollen viability, grain fill, and fruit set.
• Water Regulation & Nutrient Uptake: Improves the plant’s overall metabolic efficiency.

2. Provides Effective, Contact Disease Protection
As a protective fungicide/bactericide, copper ions disrupt pathogen cells, offering control for:

• Fungal Diseases: Downy mildew, powdery mildew, leaf spots, blights, and anthracnose.
• Bacterial Diseases: Citrus canker, bacterial spot, and fire blight.
• Specific Applications: Algae control in ponds and post-harvest fruit treatment.

3. Highly Soluble & Versatile for Multiple Application Methods

• Foliar Spray (Most Common): Rapid absorption for quick correction and protection.
• Soil Application: Addresses long-term copper deficiency in deficient soils.
• Seed Treatment: Protects seedlings and early growth stages.
• Fertigation: Easily integrates into drip or sprinkler irrigation systems.

Scientific Application Guidelines

For Micronutrient Nutrition (Correcting Deficiency):

• Rate: 0.5 – 2.0 kg per hectare as a foliar spray.
• Timing: At early growth stages or at first sign of deficiency (e.g., wilting young leaves, stunted growth).
• Frequency: 1-2 applications per season, as needed based on soil tests.

For Fungicidal/Bactericidal Protection:

• Rate: 1.0 – 4.0 kg per hectare, depending on target disease and crop.
• Timing: Begin applications preventatively or at first disease sign. Repeat at 7-14 day intervals.
• Note: Always follow label instructions for specific crop-disease combinations.
