Bordeaux Mixture is a combination of Copper Sulfate (CuSO₄) and Calcium Hydroxide (Quick Lime) mixed with water. It was first developed in the Bordeaux region of France and remains one of the most reliable fungicides in agriculture.

• Standard Ratio: 1:1:100
  • 1 kg Copper Sulfate
  • 1 kg Quick Lime
  • 100 liters of water
• Preparation:

• Dissolve copper sulfate in half the water.
• Separately dissolve lime in the remaining water.
• Slowly mix the lime solution into the copper solution while stirring continuously.
• Use immediately or within 24 hours.

🌾 Agricultural Benefits

Bordeaux Mixture is used preventively—it must be applied before disease symptoms appear. It forms a protective layer on plant surfaces, killing fungal spores and preventing germination.

✅ Key Benefits:

• Controls fungal diseases like:
  • Downy mildew
  • Powdery mildew
  • Early and late blight
  • Anthracnose
  • Leaf spots
• Effective against bacterial infections such as:
  • Bacterial blight
  • Canker
• Long-lasting protection: Adheres well to plant surfaces and resists being washed off by rain.
• Organic farming approved: Made from naturally occurring substances.

🌱 Suitable Crops

Bordeaux Mixture is widely used on:

• Grapes
• Tomatoes
• Potatoes
• Mangoes
• Bananas
• Pomegranates
• Brinjal (Eggplant)

It is especially useful during the monsoon season, when fungal infections are more likely to spread.

🧪 Application Guidelines

• Spray early morning or late afternoon to avoid sunburn.
• Avoid spraying during flowering or extreme heat.
• Use plastic or wooden containers—never metal.
• Clean sprayers thoroughly after use to prevent corrosion.

Copper is the most important micronutrient content for all crops. Copper is a fungicide used to control bacterial and fungal diseases of fruit, vegetable, nut and field crops. Some of the diseases that are controlled by this fungicide include mildew, leaf spots, blights and apple scab.

When soil is copper-deficient, young plants may develop chlorosis, a condition in which leaves yellow due to lack of chlorophyll. Copper deficiencies can also cause stunted or atypical growth, young plants in very nutrient-deficient soil may simply die.

Copper solutions have been used as part of a fungicide mixture on trees, shrubs and grapevines.  It is very effective against fungi,  bacteria and viruses.
