Katyayani Copper Oxychloride 50% WP (COC 50) Fungicide
Katyayani Copper Oxychloride 50% WP (COC 50) Fungicide
Product Description
Katyayani COC 50 is a contact, protective fungicide with Copper Oxychloride 50% WP (wettable powder). Use about 3 g per litre of water, or 1 kg per acre (1.5 kg for coffee and cardamom), as a foliar spray before the disease starts. It forms a barrier on the leaf that stops fungal spores from germinating. It protects but does not cure established infection.

Is COC 50 Preventive or Curative?
Preventive only. Copper forms a protective layer on the plant surface and stops spore germination. It cannot cure an infection that has already established, so spray before symptoms appear. Residual activity is long-lasting.

How to Spray COC 50
- Prepare a slurry: mix the powder in a little water in a bucket first.
- Add the slurry to a part-filled tank, top up with water and keep the tank agitated while spraying.
- Dose: about 3 g per litre, in 300-400 L of water per acre (1 kg per acre).
- Spray as a foliar spray before the disease appears. Cover both leaf surfaces.
- Spray when the leaves can dry reasonably quickly.
Compatibility and Precautions
- Do not spray in cool, wet, slow-drying weather. Do not use acidic tank water or acidic partners. Avoid very young seedlings before the four-leaf stage, and avoid repeated sprays with no rain in between. All of these raise the risk of leaf burn.
- Never mix copper with acidic products or lime.
- Mancozeb: physically compatible, but both are protectant (multi-site) fungicides, so mixing adds cost without much extra benefit. A copper plus systemic fungicide pairing is the better choice.
- COC 50 is compatible with many pesticides and fertilizers. Do a small jar test first.
- Copper oxychloride cannot be made at home; it is manufactured under a CIB&RC licence.
- Check the label for the waiting period before harvest.
Disclaimer
Use as per label directions. Wear gloves, mask and full-sleeve clothing while spraying. Keep away from children, food and animals. Read the label before use. Results depend on crop stage, disease pressure and weather.
