Tata Blitox Fungicide (Copper Oxychloride 50% WP)
The Ultimate "Resistance Breaker" for Fungal and Bacterial Disease Control
Tata Blitox is one of India's most trusted copper-based fungicides, manufactured by Rallis India. It is a broad-spectrum contact fungicide containing Copper Oxychloride 50% WP. Unlike standard fungicides that only target fungi, Blitox offers dual protection by effectively controlling both fungal blights and bacterial diseases.
Best For: Farmers facing resistance issues with systemic fungicides, and those needing robust protection during the rainy season against Late Blight, Downy Mildew, and Cankers.
Why Choose This Product? Key Benefits
- ⏱️Dual Action Power: Acts as both a potent Fungicide and a Bactericide, saving you the cost of buying two separate products for crops like Tomato and Citrus.
- ?️Resistance Breaker: Uses a multi-site mode of action. Pests cannot easily develop resistance to it, making it the perfect partner to rotate with systemic chemicals.
- ⏳Long-Lasting Protection: Provides a residual protective shield on the leaf surface that lasts for 7 to 14 days, depending on weather intensity.
- ?️Rainfast Formula: Excellent adherence to leaves. It sticks better than many organic fungicides, making it ideal for monsoons and high-humidity areas.
- ?Economical & Versatile: Cost-effective (approx. ₹450/acre) and registered for use on a vast range of vegetables, fruits, and plantation crops.

How It Works: Mode of Action
Blitox is a Multi-Site Contact Fungicide. It does not enter the plant system; instead, it forms a chemical barrier on the leaf surface.
- Passive Absorption: When fungal spores or bacteria land on the leaf and try to germinate using moisture, they absorb the released Copper ions (Cu2+).
- Enzyme Inhibition: Once inside the pathogen, the copper ions bind to proteins and disrupt essential enzymes required for respiration.
- Cellular Breakdown: It damages the cell membrane integrity, causing the pathogen to leak vital fluids and die. This complex attack makes it nearly impossible for pests to develop resistance.
Note: Because it is a contact fungicide, it must be sprayed before the disease enters the plant tissue for maximum results.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Vegetables (Tomato, Potato, Chilli) | Early Blight, Late Blight, Bacterial Spot, Leaf Spot |
| Fruit Crops (Grape, Citrus, Banana) | Downy Mildew, Anthracnose, Citrus Canker, Sigatoka Leaf Spot |
| Field Crops (Paddy, Groundnut) | Bacterial Leaf Blight (BLB), Brown Spot, Tikka Leaf Spot |
| Plantation (Tea, Coffee) | Blister Blight, Red Rust, Black Rot, Leaf Rust |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Vegetables (Tomato/Chilli) | 400g - 500g | 200 L | 2.5g | Exempt / 7-10 |
| Paddy (Rice) | 500g | 200 L | 2.5g | Exempt / 10 |
| Fruit Crops (Grapes/Citrus) | 400g - 600g | 500-1000 L | 2.0g - 3.0g | Check Export MRLs |
| Plantations (Tea/Coffee) | 400g - 420g | 200-400 L | 2.5g | 7-14 |
*PHI = Pre-Harvest Interval: Copper Oxychloride is often exempt from residue limits for domestic consumption, but export crops (like Grapes) require strict adherence to MRLs (often 40+ days).
How to Apply: Best Practices
- Timing: Apply proactively (before disease appears) or at the first sign of symptoms. For bacterial control, spray before monsoon showers.
- Mixing (Slurry Method): Do not dump powder directly into the tank. Mix the required quantity with a little water in a bucket to form a smooth cream (slurry), then pour this into the spray tank while stirring.
- Coverage: Use a Hollow Cone nozzle. Ensure full coverage of both upper and lower leaf surfaces, as the product only protects where it lands.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying on open flowers to prevent pollination issues.
Frequently Asked Questions
1. Can I mix Tata Blitox with antibiotics?
Yes. For bacterial diseases like Citrus Canker or Rice Leaf Blight, Blitox acts synergistically with Streptocycline. This combination is a standard recommendation for superior control.
2. Is Blitox safe for all crops?
It is safe for most, but use caution with Cucurbits (cucumber/melons) and certain Apple varieties (Russeting risk). Avoid spraying during peak flowering and when temperatures exceed 32°C.
3. Can I mix Blitox with other pesticides?
It is compatible with Wettable Sulphur and most common insecticides. WARNING: Do NOT mix with Lime Sulphur or highly alkaline substances. Always perform a small jar test first.
4. Does rain wash it off immediately?
No. Being a Wettable Powder (WP) with "fixed" copper, it has excellent rainfastness. Once the spray dries on the leaf, it sticks well, making it ideal for the rainy season.
5. What is the difference between Blitox and Blue Copper?
"Blue Copper" is a generic term for Copper Oxychloride. Tata Blitox is the branded version from Rallis India, known for superior formulation quality, better suspension in water, and consistent particle size.
