Roket Insecticide (Profenofos 40% + Cypermethrin 4% EC)
The Ultimate "Double-Engine" Protection Against Bollworms & Sucking Pests
Roket Insecticide by PI Industries is a powerful, broad-spectrum solution designed for serious farmers. It combines two active ingredients to attack pests in two ways: immediate contact shock and deep stomach poison. Whether you are fighting the stubborn Bollworm complex in cotton or Leaf Folders in paddy, Roket delivers rapid knockdown and long-lasting safety.
Best For: Farmers seeking a single, cost-effective spray to control both caterpillars (larvae) and sucking pests simultaneously.
Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown Action:
Contains Cypermethrin (4%) which shocks the pest's nervous system immediately upon contact, stopping crop damage within minutes. -
🛡️
Kills Eggs (Ovicidal):
The Profenofos component destroys pest eggs before they hatch, preventing future population explosions. -
⏳
Translaminar Penetration:
The spray penetrates leaf tissues to kill hidden pests (like aphids and mites) feeding on the underside of leaves. -
🌧️
Rainfast Efficiency:
The high-quality EC formulation sticks well to plant surfaces and becomes rainfast within 2 to 4 hours. -
🌿
Synergistic Power:
Profenofos prevents the pest from breaking down Cypermethrin, making this combination effective even against resistant pests.

How It Works: Mode of Action
Roket uses a strategic dual-mode attack to ensure high mortality in pest populations:
- Nervous System Overload (Cypermethrin): Upon contact, it keeps the insect's sodium channels open. This causes the nerves to fire repeatedly, leading to immediate paralysis and "knockdown."
- Enzyme Inhibition (Profenofos): It enters the insect's system through feeding (stomach poison) and inhibits the enzyme Acetylcholinesterase. This causes toxic accumulation of neurotransmitters, leading to death.
- Anti-Resistance Mechanism: Profenofos blocks the enzymes that pests usually use to digest Cypermethrin, making the combination far more lethal than using either chemical alone.
Result: The insect stops feeding immediately, drops off the plant, and dies.
Target Crops & Pests

|---|---|
| Cotton | Bollworm Complex (American, Pink, Spotted), Aphids, Jassids, Whiteflies, Thrips |
| Paddy (Rice) | Stem Borer, Leaf Folder, Green Leaf Hopper (GLH) |
| Vegetables (Brinjal, Tomato, Okra) | Shoot & Fruit Borer, Diamondback Moth (DBM), Aphids |
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 Litres | 2.0 - 3.0 ml | 14 Days |
| Paddy | 400 - 500 ml | 200 Litres | 2.0 - 2.5 ml | 14 Days |
| Vegetables | 400 - 500 ml | 150 - 200 Litres | 2.5 - 3.0 ml | 7 - 14 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure food safety.
How to Apply: Best Practices
- Timing: Apply when pest population reaches the Economic Threshold Level (ETL). Avoid spraying during peak mid-day heat.
- Mixing: This is an EC formulation. Pour the required dose into a small quantity of water first, stir well, then add to the main tank.
- Coverage: Use fine-spray nozzles (hollow cone) to ensure the liquid reaches the underside of leaves where aphids and mites hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This product is toxic if inhaled or absorbed through the skin.
Frequently Asked Questions
1. Can I mix Roket with other pesticides?
Since Roket is already a mixture of two chemicals, do not mix it with other Organophosphates or Pyrethroids. It is generally compatible with common fungicides, but a physical jar test is recommended.
2. Is Roket safe for all vegetable crops?
Caution: Avoid using Roket on Cucurbits (Cucumber, Melons, Squash) as it may cause burning (phytotoxicity) on the leaves of these sensitive plants.
3. What is the dose for a 15-Litre spray pump?
For most crops, use approximately 40 ml to 50 ml of Roket per 15-litre tank.
4. Does it control Pink Bollworm in Cotton?
Yes. Roket is effective against Pink Bollworm eggs and young larvae. However, for larvae already deep inside the boll, systemic control may be required.
5. Can I use this on crops for export?
Profenofos has strict residue limits in the EU and USA. Consult an agronomist before using Roket on crops intended for export to these regions.
