Copper Sulphate (Fungicide)

Copper Sulphate (کاپر سلفیٹ) is a broad-spectrum fungicide and bactericide trusted by gardeners to fight diseases like blight, rust, powdery mildew, and bacterial leaf spots. It works by forming a protective barrier on leaves and stems, preventing fungal spores and bacteria from spreading.

This chemical is especially useful in Pakistan’s humid weather, particularly during monsoon and after rainfall, when fungal infections like tomato blight, chilli leaf spot, or okra mildew are common.

Benefits:

• Fungal Disease Control: Stops early and late blight, mildew, and rust

• Protective Coating: Forms a barrier on plant surfaces against infection
• Works in Humid & Rainy Weather: Ideal for Pakistani gardens during monsoon

• Mixing Ratio: Mix 3–5 grams per liter of water
• Application: Spray on both sides of leaves every 10–15 days, especially during high humidity or rain
• Best Time to Spray: Early morning or evening. Avoid spraying under strong sunlight or just before rain
• Where to Use: Safe for vegetables, fruit trees, and ornamentals when used correctly

⚠️ Precautions:

• Wear gloves and mask while mixing or spraying
• Keep away from children, pets, and edible surfaces
• Do not mix with neem oil, acidic sprays, or micronutrients
• Avoid using during flowering (unless necessary)
