Kocide 3000 Fungicide (Bharat Certis): Expert Review, Dosage & Benefits
The gold standard in Copper Hydroxide technology for superior control of fungal and bacterial crop diseases.
Kocide 3000 is a technologically advanced copper fungicide formerly managed by Corteva and now brought to you by Bharat Certis AgriScience. Unlike older copper powders that require heavy dosage, Kocide 3000 utilizes patented BioActive™ Technology. This allows it to fight diseases like Anthracnose, Bacterial Blight, and Canker with significantly less metallic copper, ensuring crop safety and better environmental health.
Why Choose This Product? Key Benefits
- ⏱️Superior Rainfastness: Advanced sticking agents ensure the formula binds to leaves quickly, resisting wash-off from light to moderate rains.
- ?️Dual Action Protection: Acts as a powerful shield against both Fungal and Bacterial infections simultaneously.
- ⏳BioActive™ Technology: Optimized particle size releases copper ions in the "Goldilocks Zone"—strong enough to kill germs, but gentle on the plant.
- ?️Eco-Friendly Formulation: Delivers maximum results with 30% less metallic copper per acre compared to generic copper oxychloride.
- ?Crop Safety (Low Phytotoxicity): The high-purity WG formulation reduces the risk of leaf burn (scorching) often seen with older copper powders.
Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Kocide® 3000 |
| Technical Name | Copper Hydroxide 46.1% DF (Dry Flowable) |

How It Works: Mode of Action
Kocide 3000 acts as a broad-spectrum contact fungicide and bactericide. It works through a "Multi-Site" mechanism, making it difficult for pests to develop resistance.
- Contact & Release: When mixed with water and sprayed, the micro-granules release biologically active Copper ions ($Cu^{2+}$) onto the leaf surface.
- Absorption: Fungal spores or bacteria absorb these ions upon contact.
- Cellular Destruction: The copper ions disrupt the pathogen's enzymes and cell proteins, effectively destroying the cell membrane and preventing infection.
Note: It acts primarily as a preventive shield. It prevents spores from germinating but does not cure diseases once they have deeply penetrated the tissue.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Chilli | Anthracnose (Dieback/Fruit Rot), Bacterial Leaf Spot |
| Cotton | Bacterial Blight (Black Arm Disease) |
| Citrus & Potato | Citrus Canker, Late Blight |
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) |
|---|---|---|---|---|
| Chilli | 500 g | 200 L | 2.5 g | 0-3* |
| Cotton | 500 g | 200 L | 2.5 g | -- |
| Citrus | 600 g | 400 L | 1.5 g | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. *For vegetables, copper generally allows harvest shortly after spray dries, but always check local label instructions.
How to Apply: Best Practices
- Timing: Apply purely preventively (before disease appears) or at the very first sign of spotting. For Chilli, start spraying from fruit setting.
- Mixing: Add Kocide granules to the water first and let them dissolve. Do NOT mix with Aliette (Fosetyl-Al) or highly acidic/alkaline chemicals.
- Coverage: Ensure thorough coverage of both upper and lower leaf surfaces. Use clean water with a pH between 6.5 and 7.5.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling dust.
Frequently Asked Questions
1. Is Kocide 3000 from Corteva or Bharat Certis?
Currently, the product is marketed in India by Bharat Certis AgriScience. You may see "Corteva" on older online listings, but the authentic fresh stock now carries the Bharat Certis logo. The quality remains identical.
2. Can I use Kocide 3000 to cure established diseases?
No, Kocide is primarily a protectant. It prevents disease spread. For active infections (like Late Blight), mix it with a curative systemic fungicide for "clean up" action.
3. Is it better than Blue Copper (Blitox)?
Yes. Kocide 3000 requires a lower dose (500g vs 1kg/acre), sticks better during rain, and has a lower risk of burning the plant compared to older Copper Oxychloride formulations.
4. Can I mix antibiotics (Streptocycline) with it?
You can, but Kocide 3000 is powerful enough against bacteria that you often do not need to add extra antibiotics, helping you save money and reduce resistance.
5. Where can I buy this in Telangana?
It is available at major dealers like Hari Om Agro (Adilabad) and online via BigHaat or RythuKart with delivery to Hyderabad and surrounding districts.
