How It Works: Mode of Action
Permasect targets the nervous system of the insect.
- Entry: The chemical enters the insect's body through contact (skin) or ingestion (eating treated leaves).
- Attack: It binds to the sodium channels in the nerve cells, forcing them to stay open.
- Result: This causes repetitive nerve firing (tremors), leading to paralysis and death.
Note: Because it is a "Type I" pyrethroid, you will often see insects shaking or agitated immediately after spraying before they drop dead.

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 | Check 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 | Check Label |
*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 first sign of egg hatching or early instar larvae (small worms). It is less effective on fully grown worms.
- Mixing: Use clean, slightly acidic water. Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulfur.
- Coverage: Permasect is a contact poison. Ensure full coverage of the foliage ("spray to run-off") for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling the spray mist.
Frequently Asked Questions
1. Does Permasect control sucking pests?
Yes, it is effective against Jassids and Thrips, but its primary strength is against caterpillars (Lepidoptera) and beetles.
2. Can I use Permasect on all crops?
It is primarily recommended for Cotton, Vegetables (like Brinjal/Okra), and Pulses. Avoid using on crops not listed on the label.
3. Is it safe for fish?
No. Permethrin is highly toxic to fish and aquatic life. Do not spray near ponds, rivers, or water bodies.
4. What is the "Jitter" effect?
It is the visible sign that the medicine is working. Pests become hyperactive and shake uncontrollably before becoming paralyzed and dying.
5. Can I mix it with other insecticides?
Farmers often use it in rotation or mixtures, but avoid mixing with highly alkaline chemicals. Always perform a small jar test before tank mixing.
