Permit-99 Insecticide (Profenofos 40% + Cypermethrin 4% EC)
The Ultimate "One-Shot" Solution for Hard-to-Kill Bollworms and Sucking Pests.
HPM Permit-99 is a high-power combination insecticide designed for serious farmers. It blends two powerful chemistries—Profenofos and Cypermethrin—to deliver a double attack on pests. Whether the insects are flying, crawling, or hiding under the leaves, Permit-99 reaches them.
Best For: Farmers facing resistance issues where normal sprays fail. It is excellent for controlling the entire Bollworm complex in Cotton and borers in vegetables.
Why Choose This Product? Key Benefits
- ⏱️Instant Knockdown: The Cypermethrin component delivers a "shock effect," instantly paralyzing pests and stopping them from damaging your crop immediately.
- ?️Dual-Action Power: Combines two modes of action to kill insects that have developed resistance to single-chemical sprays.
- ⏳Kills Hidden Pests (Translaminar): Profenofos penetrates the leaf surface, creating a toxic reservoir that kills pests hiding or mining on the underside of leaves.
- ?️Excellent Rainfastness: Once dried (1-2 hours), it is absorbed into the leaf and is not easily washed away by rain, making it perfect for monsoon application.
- ?Mite Control: Unlike standard sprays, Permit-99 also works against mites (acaricidal action), giving you complete field protection.

How It Works: Mode of Action
Permit-99 utilizes a "Synergistic Attack" strategy to ensure no pest survives:
- Nervous System Overload: Profenofos inhibits the enzyme Acetylcholinesterase. This prevents the insect's nerves from resetting, causing constant firing and exhaustion.
- Rapid Paralysis: Cypermethrin attacks the sodium channels in the insect's nerve axons, keeping them open. This causes immediate tremors, knockdown, and paralysis.
- Deep Cleaning: While Cypermethrin handles surface pests, Profenofos absorbs into the leaf tissues (translaminar), killing larvae that bore inside stems or hide beneath leaves.
Result: Complete control of eggs, larvae, and adult insects.
Target Crops & Pests

| Other Crops | Effective on Soybean (Girdle beetle/Semilooper) and general chewing 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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 600 ml | 200 - 400 L | 2 - 3 ml | 14 Days |
| Vegetables | 400 - 500 ml | 200 L | 2 - 2.5 ml | 14 Days |
| Soybean/Pulses | 400 - 500 ml | 200 L | 2 - 2.5 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: Apply when you see the first signs of pest incidence (Economic Threshold Level). For Bollworms, spray when 5% of bolls are damaged.
- Mixing: Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulfur, as this will destroy the effectiveness of Profenofos.
- Coverage: Ensure uniform coverage. The "Translaminar" effect works best when the spray properly covers the foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near water bodies (fish ponds/rivers).
Frequently Asked Questions
1. Does Permit-99 control Mites (Mokkaku/Red Mite)?
Yes. The Profenofos content in Permit-99 has strong acaricidal properties, making it effective against mites in addition to insects.
2. Can I use this during the rainy season?
Yes. Permit-99 is absorbed into the leaf tissues quickly (within 1-2 hours), making it rainfast. It is a great choice for monsoon sprays.
3. Why is it called a "Synergistic" product?
It mixes two chemicals that help each other work better. Profenofos stops the enzymes that insects use to resist Cypermethrin, making the spray highly effective even on tough pests.
4. What is the waiting period before harvest?
The Pre-Harvest Interval (PHI) is 14 days. Do not harvest vegetables or cotton within 2 weeks of spraying to ensure residue safety.
5. Who manufactures Permit-99?
Permit-99 is manufactured by HPM Chemicals & Fertilizers Ltd., a trusted name in Indian crop protection.
