Permasect Insecticide (Permethrin 25% EC) by Coromandel
The trusted "Gromor" solution for rapid control of Bollworms and Borers.
Permasect is a powerful, broad-spectrum insecticide manufactured by Coromandel International Limited. Formulated with Permethrin 25% EC, it is the go-to choice for Indian farmers battling tough caterpillars and borers.
Why it works: Unlike standard sprays, Permasect acts as a "double engine" against pests—working upon contact (touch) and ingestion (eating). It is specifically famous for its ability to knock down the Bollworm complex in Cotton and fruit borers in vegetables, offering premium protection at an affordable price.
Why Choose This Product? Key Benefits
- ⏱️Instant "Knockdown" Power: Paralyzes the pest's nervous system immediately upon contact, stopping crop damage instantly.
- ?️Multi-Action Protection: Acts as a contact poison, a stomach poison, and an anti-feedant (stops pests from eating).
- ⏳Long-Lasting Residue: Stays active on the leaf surface for days, preventing new pest attacks from neighboring fields.
- ?️Excellent Rainfastness: The oil-based (EC) formula sticks to waxy leaves and insect skins, resisting wash-off from light rains.
- ?Repellent Properties: Creates a chemical barrier that discourages adult moths from laying eggs on your crops.

How It Works: Mode of Action
Permasect targets the insect's nervous system. It acts as a "Type I" pyrethroid, which causes the following chain reaction:
- Rapid Entry: The chemical penetrates the insect's outer skin (cuticle) or enters through the stomach.
- Nerve Overload: It binds to the sodium channels in the nerves, keeping them open. This causes the nerves to fire repeatedly without stopping.
- The "Jitters": The pest experiences extreme tremors and hyperactivity (The Jitters), loses coordination, falls off the plant, and dies.
Note: Because it irritates the insect, pests stop feeding almost immediately after contact, saving your crop even before they die.

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 | 200 – 500 ml | 200 – 400 L | 1.0 – 2.5 ml | 7 - 14 Days (Refer Label) |
| Vegetables | 200 – 300 ml | 200 L | 1.0 – 1.5 ml | 3 - 7 Days |
| Pulses | 200 – 400 ml | 200 L | 1.0 – 2.0 ml | 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 when you first see eggs or small larvae (caterpillars). It works best on young pests. Avoid spraying during the hottest part of the day.
- Mixing: Pour the required amount of Permasect into a little water to make a white emulsion, then add the rest of the water. Ensure the water pH is neutral or slightly acidic.
- Coverage: Permasect is a contact killer, so coverage is key. Use a hollow-cone nozzle and spray until the leaves are fully wet (spray to run-off).
- 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. Can Permasect kill adult moths?
Yes. It has excellent contact action that knocks down adult moths, preventing them from laying more eggs in your field.
2. Is it effective against sucking pests?
Permasect provides good control against Jassids and Thrips due to its contact action, but for heavy Aphid infestations, a systemic insecticide might be needed.
3. Can I mix Permasect with other chemicals?
Farmers often use it in rotation or tank mixes, but ensure the other chemical is not alkaline (like Bordeaux mixture), as this will destroy Permasect's power.
4. What should I do if I feel itching after spraying?
Permethrin can cause a tingling sensation on the skin. Wash the area with soap and water immediately. Applying Vitamin E oil can help soothe the sensation.
5. How fast does it work?
It works very fast. You will often see pests becoming hyperactive and falling off the crop within minutes to hours of application (the "knockdown" effect).
