Toofan - Chlorpyrifos 16% + Alpha-Cypermethrin 1% EC - HPM

HPM Toofan Product Overview

HPM Toofan is a Chlorpyrifos 16% + Alpha-Cypermethrin 1% EC combination insecticide. The current Indian package label covers foliar control of the cotton bollworm complex: American bollworm, spotted bollworm, and pink bollworm. Use Toofan only for the crop, pests, dose, water volume, re-entry period, pre-harvest interval, and application frequency printed on the current pack label.

The two active ingredients act at different insect nerve targets. Chlorpyrifos is an organophosphate acetylcholinesterase inhibitor in IRAC Group 1B, while alpha-cypermethrin is a synthetic pyrethroid sodium-channel modulator in IRAC Group 3A. The formulation acts through contact and stomach exposure and is intended for labelled foliar application.

Why Choose HPM Toofan?

• Verified combination: Chlorpyrifos 16% + Alpha-Cypermethrin 1% EC.
• Labelled cotton use: Covers American, spotted, and pink bollworms as the cotton bollworm complex.
• Dual mode-of-action identity: IRAC Groups 1B and 3A act at different insect nerve targets.
• Clear application directions: The label specifies formulation dose, water volume, re-entry, pre-harvest interval, and frequency.
• Multiple pack sizes: Choose from the available packs according to the labelled treatment requirement.

Technical Specifications

How It Works: Mode of Action

1. Chlorpyrifos — IRAC 1B: inhibits acetylcholinesterase, disrupting normal nerve-signal termination.
2. Alpha-Cypermethrin — IRAC 3A: modulates voltage-gated sodium channels, disrupting nerve-impulse transmission.
3. Labelled exposure: the formulation acts through contact and ingestion when applied as a foliar spray with the required coverage.

A product containing two active ingredients should not be treated as a substitute for resistance management. Follow local integrated-pest-management guidance and avoid unnecessary repeat exposure to IRAC Groups 1B and 3A.

Labelled Cotton Use and Dosage

The current label permits 2–3 sprays depending on pest incidence. The per-acre figures are approximate conversions from the label's per-hectare directions. Do not create a universal dose per litre; use the complete dose and water-volume directions on the current pack.

Application Best Practices

• Confirm the target: Use only on cotton for the bollworm pests named on the current label.
• Timing: Apply preferably in the morning or evening according to pest incidence.
• Weather: Avoid high wind and ensure there is no rainfall for at least five hours after application.
• Mixing: Measure the required quantity, mix first with a small amount of water, then add the remaining labelled water while agitating.
• Equipment: Use a manually operated knapsack or suitable power-operated sprayer with the label-directed fan/high- or low-volume nozzle.
• Coverage: Apply evenly while preventing spray drift and contamination of people, animals, water, or neighbouring crops.

Frequently Asked Questions

1. Which crop is listed on the current Toofan label?
Cotton is listed for American, spotted, and pink bollworms. Do not transfer this label dose to paddy, another crop, or structural termite treatment.

2. What is the Toofan dose per acre?
The label gives 2,500 ml/ha, approximately 1,000 ml/acre, with 500–750 L water/ha. Always confirm the current pack label before measuring.

3. Can I use one dose per litre for every sprayer?
No. The label provides a total formulation dose and a water-volume range; a universal per-litre conversion could be misleading.

4. How long should workers wait before re-entering?
The current label states a 24-hour re-entry period.

5. What is the pre-harvest interval?
The current label states 15 days for cotton.

6. Is Toofan the same as HPM Terminator-505?
No. Toofan contains Chlorpyrifos 16% + Alpha-Cypermethrin 1% EC. Terminator-505 is a separate formulation containing Chlorpyrifos 50% + Cypermethrin 5% EC. Their doses must not be interchanged.
