Colfos Insecticide (Ethion 40% + Cypermethrin 5% EC)
The "One-Shot" Solution for Bollworms and Sucking Pests
Colfos Insecticide by PI Industries is a powerful dual-action formula designed to protect your crops from tough pest complexes. By combining two strong active ingredients—Ethion and Cypermethrin—it solves the problem of worms (caterpillars) and sucking pests (like mites) in a single spray. It is specifically engineered for crops like Cotton and Chilli, offering a reliable defense against pests that have developed resistance to ordinary sprays.

How It Works: Mode of Action
Colfos uses a "Double Tap" method to ensure pests cannot survive. It attacks two different parts of the insect's body simultaneously.
- Nervous System Shock (Cypermethrin): Attacks the insect's sodium channels, causing instant paralysis and "knockdown" so the pest stops feeding immediately.
- Enzyme Blockage (Ethion): Inhibits the AChE enzyme, which creates a continuous nerve firing. This works via contact and stomach action, killing tough pests like mites.
- Synergistic Protection: The Ethion component stops the insect from digesting the Cypermethrin, making the spray much more lethal than if you used the chemicals separately.

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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 500 ml | 200 L | 2.5 ml | 15 Days |
| Chilli | 400 - 500 ml | 200 L | 2.5 ml | 10 Days |
| Vegetables | 350 - 400 ml | 150 - 200 L | 2.0 - 2.5 ml | 7 - 14 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray in the early morning or late evening. Avoid spraying during the hot mid-day sun to prevent evaporation and damage to crop leaves.
- Mixing: Colfos is compatible with neutral fungicides (like Mancozeb). Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulphur.
- Coverage: This is a contact poison. Ensure you spray thoroughly to cover the entire plant canopy, including the undersides of leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Colfos effective against mites?
Yes, Colfos is very effective against mites (acaricide) because it contains 40% Ethion, which targets mites that ordinary sprays often miss.
2. Does it kill Pink Bollworm?
Yes, Colfos is designed to control the entire "Bollworm Complex," including the Pink Bollworm, Spotted Bollworm, and American Bollworm.
3. What happens if it rains after spraying?
Colfos is rainfast. If it rains 3 to 4 hours after you finish spraying, the medicine will remain effective on the plant.
4. Can I mix it with other products?
You can mix it with neutral-reaction fungicides. However, never mix it with alkaline substances, as this will destroy the chemical effectiveness.
5. Is it safe for bees?
Colfos is toxic to honeybees. To protect them, avoid spraying when the crop is in full bloom, or spray only in the evening when bees are not active.
