Copper Sulphate

Copper Sulphate: A Comprehensive Guide for Agriculture and Horticulture

Overview

Copper sulphate, a blue crystalline powder, is a versatile chemical compound extensively used in agriculture and horticulture. It serves dual purposes: as a fungicide and as a source of essential copper for plants.

Key Features

• Versatility: Copper sulphate is a dual-action compound, acting both as a fungicide and a nutrient source.
• Broad Spectrum: Effective against a wide array of fungal diseases, including downy mildew, powdery mildew, and more.
• Essential Nutrient: Provides plants with copper, vital for their growth and development.
• Aquatic Herbicide: Can be used to control algae and unwanted aquatic plants.

Mode of Action

Copper sulphate releases copper ions into the soil. These ions are detrimental to fungi and other pathogens, attacking their cell walls and membranes. Concurrently, plants absorb these copper ions, aiding in their cellular processes and growth.

Targeted Fungal Diseases

• Downy Mildew
• Powdery Mildew
• Leaf Spot
• Anthracnose
• Botrytis Blight
• Black Rot
• Phytophthora Blight

Application & Dosage

Usage Instructions

For foliar application, mix 3 grams of copper sulphate with 1 liter of water. Ensure thorough mixing to achieve a uniform solution. Spray the solution evenly on the plant leaves, ensuring coverage on both the upper and lower surfaces. It's recommended to spray during the cooler parts of the day, either early morning or late afternoon, to prevent leaf burn.

Safety Precautions

• Always wear protective gloves and eyewear when handling and applying copper sulphate.
• Store in a cool, dry place, away from children and pets.
• Do not ingest. If ingested, seek medical attention immediately.
• Avoid contact with eyes. In case of contact, rinse thoroughly with water.

Copper sulphate is an indispensable tool for farmers and gardeners. Its dual-action of providing essential nutrients and acting against fungal diseases makes it a must-have in every agricultural toolkit. Proper application and adherence to recommended dosages ensure healthy, disease-free crops and bountiful yields.
