Ferotia Gold Insecticide (Diafenthiuron 50% WP) - Coromandel
The Ultimate Solution for Whiteflies, Mites, and Sucking Pests
Ferotia Gold by Coromandel International is a powerful, broad-spectrum insecticide designed to protect your crops from tough sucking pests. Powered by Diafenthiuron 50% WP, it offers a unique "3-way attack" mechanism that kills pests hidden deep within the crop canopy. Unlike older chemicals, Ferotia Gold not only eliminates pests but also provides a "Phytotonic Effect," turning into urea after application to boost plant greenness and vigor. It is the top choice for farmers growing Cotton, Chilli, and Vegetables.
Why Choose This Product? Key Benefits
- ⏱️Immediate Anti-Feeding Action: Pests stop feeding and damaging your crop immediately after contact, even if they die a few hours later.
- ?️Controls Hidden Pests (Translaminar): The medicine penetrates through the leaf surface to kill pests hiding on the underside (bottom) of the leaves.
- ⏳Long-Lasting Protection: Provides extended control for 10 to 14 days, reducing the need for frequent spraying and saving you money.
- ?️Unique Vapor Action: It releases a vapor (gas) that reaches pests hiding in dense flower buds, crevices, and overlapping leaves.
- ?Phytotonic "Greening" Effect: After killing the pest, the chemical degrades into Urea, giving your crop a nitrogen boost for lush green growth.

How It Works: Mode of Action
- Activation by Sunlight: Ferotia Gold is a "Pro-Insecticide." It remains inactive in the packet but becomes highly toxic to pests once sprayed and exposed to sunlight or insect enzymes.
- Stops Energy Production: Once inside the pest, it blocks the production of ATP (energy). The insect becomes paralyzed, stops feeding immediately, and dies from energy starvation.
- Triple Attack Strategy: It works via Contact (direct spray), Stomach (eating treated leaves), and Vapor (gas phase) action to ensure no pest survives.
Target Crops & Pests

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) |
|---|---|---|---|---|
| Cotton | 240 - 250 g | 200 L | 1.25 g/L | 21 |
| Cabbage / Cauliflower | 240 - 250 g | 200 L | 1.25 g/L | 7 |
| Chilli / Brinjal | 240 - 250 g | 200 L | 1.25 g/L | 3 |
| Cardamom | 320 - 330 g | High Volume | 1.3 g/L | 21-30 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray at the "Economic Threshold Level" (initial signs of pest attack) for best results. For Cotton, apply during mid-season when the canopy is dense.
- Mixing: Ferotia Gold is sensitive to pH. Do NOT mix with highly acidic fertilizers or alkaline mixtures (like Bordeaux mixture). Mix well in water to form a uniform suspension.
- Coverage: Ensure thorough coverage. For vegetables like Cabbage, use a "sticker" or surfactant to help the medicine stick to waxy leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds as it is toxic to aquatic life.
Frequently Asked Questions
1. Does Ferotia Gold kill mites?
Yes, it is excellent for controlling Red Spider Mites and Yellow Mites, especially in Chilli (Murda complex) and Brinjal crops.
2. What is the "greening effect" mentioned?
Ferotia Gold degrades into a urea-derivative. This acts as a nitrogen source, helping plants recover from pest damage and turning leaves lush green.
3. Is it safe for beneficial insects?
Yes, Ferotia Gold is generally safe for beneficial predators like ladybugs and lacewings, making it a good fit for Integrated Pest Management (IPM).
4. Can I mix Ferotia Gold with other chemicals?
It is compatible with most neutral insecticides and PGRs. However, avoid mixing with strong acids or alkalis (like lime sulfur or copper fungicides) to prevent spoilage.
5. How does it control pests on the underside of leaves?
It has "Translaminar Action," meaning it soaks into the leaf and moves to the other side, killing pests hiding underneath. Its "Vapor Action" also reaches hidden crevices.
