HPM Toofan Insecticide (Chlorpyriphos 16% + Alphacypermethrin 1% EC)
The "Double Engine" Solution for Cotton Bollworms and Paddy Pests.
HPM Toofan is a powerful broad-spectrum insecticide that combines two distinct active ingredients to deliver a "knockdown" punch to hard-to-kill pests. By mixing Chlorpyriphos (16%) and Alphacypermethrin (1%), this formulation attacks insects through two different pathways—contact and vapor—ensuring complete protection even in dense crop canopies.
Best For: Farmers facing heavy infestations of Pink Bollworm, Spotted Bollworm, or Leaf Folders who need an immediate, cost-effective solution.

How It Works: Mode of Action
Toofan attacks the insect's nervous system from two angles, causing rapid paralysis and death:
- Systemic & Contact (Chlorpyriphos): It inhibits the enzyme Acetylcholinesterase (AChE). This causes a "traffic jam" in the nerve signals, leading to uncontrollable tremors in the insect.
- Stomach & Contact (Alphacypermethrin): This attacks the sodium channels in the nerve fibers. It acts like an electric shock, causing immediate paralysis (Knockdown) so the pest stops eating your crop instantly.
- Fumigant Action: The formulation releases a vapor that travels into the soil cracks and dense foliage, killing pests hiding where sprays cannot reach.
This synergistic "1+1=3" effect makes it harder for pests to survive compared to using either chemical alone.
Target Crops & Pests

| Vegetables | Fruit Borers, Shoot Borers, Thrips, 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 | 1000 ml | 200 - 300 L | 3.5 - 5 ml | 15 Days |
| Paddy (Rice) | 1000 ml | 200 - 300 L | 3.5 - 5 ml | 15 Days |
| Vegetables | 800 - 1000 ml | 200 L | 4 - 5 ml | 7 - 10 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure residues are within safe limits.
How to Apply: Best Practices
- Timing: Apply during the evening hours. This product is toxic to honeybees, and evening application avoids peak pollination times.
- Mixing: Add the required quantity of Toofan to a small amount of water to make a solution, then add the remaining water. Stir well.
- Coverage: For best results against Bollworms, use a Mist Blower or a battery sprayer with a high-volume nozzle to ensure the chemical penetrates the crop canopy.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not wash spray containers in ponds or rivers as it is toxic to fish.
Frequently Asked Questions
1. Does Toofan control Pink Bollworm in Cotton?
Yes, Toofan is highly effective against the Pink Bollworm complex due to its combination of contact action and vapor action, which reaches larvae inside the bolls.
2. What is the dosage for a 15-liter spray tank?
For a standard 15-liter pump, use approximately 50ml to 75ml of Toofan, depending on the severity of the pest infestation.
3. Can I use Toofan on vegetable crops?
Yes, it is effective on vegetables for borers. However, strict adherence to the Pre-Harvest Interval (waiting period) is necessary before picking the vegetables for consumption.
4. Is this product safe for Honeybees?
No, Toofan is toxic to bees. Avoid spraying during flowering stages or spray strictly in the late evening when bees are not foraging.
5. What is the result time (Rainfastness)?
Toofan shows immediate knockdown effects. It generally requires 2-3 hours without rain after spraying to become rainfast.
