HPM Toofan Insecticide (Chlorpyriphos 16% + Alphacypermethrin 1% EC)
The "Double Engine" Protection for Cotton and Paddy against Hard-to-Kill Pests.
HPM Toofan is a powerful combination insecticide designed to fight the toughest crop enemies. By blending the long-lasting power of Chlorpyriphos with the instant "knockdown" speed of Alphacypermethrin, Toofan ensures that pests like the Pink Bollworm and Stem Borer are stopped immediately.
Best For: Farmers seeking a single solution for biting, chewing, and boring insects in Cotton and Rice (Paddy).
Why Choose This Product? Key Benefits
- ⏱️Instant Knockdown Power: The Alphacypermethrin component attacks the pest's nervous system instantly, causing paralysis within minutes of contact.
- ?️Double Engine Action: Combines two modes of action (Contact & Stomach) to kill pests that have developed resistance to single-chemical sprays.
- ⏳Long-Lasting Residual Effect: Chlorpyriphos remains active on the plant surface, providing continued protection for days after spraying.
- ?️Vapor Action for Hidden Pests: Creates a fumigation effect that penetrates cotton bolls and rice stems to reach hidden pests like the Pink Bollworm.
- ?Versatile Crop Protection: Highly effective for both Cotton (Bollworm complex) and Rice (Stem Borer & Leaf Folder), as well as termite control.

How It Works: Mode of Action
Toofan uses a synergistic approach to overwhelm the insect's defense systems:
[Image of insect nervous system synapse inhibition diagram]- Systemic Nervous Failure: Chlorpyriphos inhibits the enzyme acetylcholinesterase (AChE), while Alphacypermethrin keeps sodium channels open. This causes continuous nerve firing, tremors, and paralysis.
- Contact & Stomach Poison: Pests are killed if they touch the spray or eat a treated leaf.
- Fumigant Action: The formulation releases a vapor (approx $2.7 \\times 10^{-3}$ Pa vapor pressure) that travels into narrow cracks, leaf folds, and bolls to kill pests hiding inside.
This multi-pronged attack ensures that even resistant pests cannot survive the exposure.
Target Crops & Pests
[Image of pink bollworm life cycle on cotton]| Crop | Target Pest(s) |
|---|---|
| Cotton | American Bollworm, Spotted Bollworm, Pink Bollworm |
| Paddy (Rice) | Yellow Stem Borer, Leaf Folder |
| Non-Crop Area | Termites (Structural & Soil treatment) |
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 | 1000 ml | 200 - 300 L | 3.5 - 5 ml | 15 |
| Paddy (Rice) | 1000 ml | 200 - 300 L | 3.5 - 5 ml | 15 |
| Termites (Soil) | Depends on Area | - | 15 - 20 ml | - |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Important for export crops.
How to Apply: Best Practices
- Timing: Spray in the cool hours of the late evening to avoid killing beneficial honey bees and to reduce evaporation.
- Mixing: Add the required quantity of Toofan to a small amount of water first to create a white emulsion, then pour into the main tank.
- Coverage: Use a Mist Blower or battery sprayer with an atomizer attachment for best results. The fine mist penetrates the cotton canopy better than coarse drops.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use near fish ponds.
Frequently Asked Questions
1. Does Toofan kill Pink Bollworm effectively?
Yes. Because of its vapor action, Toofan can penetrate into the cotton boll where the Pink Bollworm hides, providing better control than contact-only sprays.
2. Can I use this product on Vegetables?
It is primarily recommended for Cotton and Paddy. If used on other crops, strict adherence to the 15-day waiting period is required to ensure food safety.
3. Is HPM Toofan safe for fish?
No. The formulation is highly toxic to fish. Do not drain paddy water into canals or ponds after spraying.
4. What is the antidote in case of accidental poisoning?
The specific antidote is Atropine Sulphate, administered by a medical professional. Do not use Morphine.
5. How quickly does it work?
You will see "knockdown" effects (insects falling off plants) within minutes due to the Alphacypermethrin component.
