Item description
HPM Knock Down Super Lambda-Cyhalothrin 5% EC Insecticide Overview
HPM Knock Down Super is a non-systemic synthetic pyrethroid insecticide containing Lambda-Cyhalothrin 5% EC.
It acts through contact and ingestion and is classified as an IRAC Group 3A sodium-channel modulator. The HPM product record lists it for specified insect pests in cotton and rice (paddy). Use it only for a crop and pest printed on the supplied pack label, at that label's rate, water volume and waiting period.
Important: This 5% EC formulation is not interchangeable with Lambda-Cyhalothrin 2.5% EC, 4.9% CS or combination products. Never transfer a dose from another concentration or formulation.

How It Works: IRAC Group 3A
Lambda-Cyhalothrin is a pyrethroid sodium-channel modulator. After a target insect contacts treated surfaces or ingests treated plant material, the active ingredient disrupts normal nerve signalling. This produces nervous-system hyperexcitation, paralysis and death.
- Exposure: Activity occurs through contact and ingestion; this is not a systemic insecticide.
- Target site: Lambda-Cyhalothrin modulates voltage-gated sodium channels in the insect nervous system.
- Resistance stewardship: Avoid repeatedly exposing successive pest generations to Group 3A. Where local guidance and each product label allow, rotate with a different effective IRAC group. Rotation does not mean tank mixing.
HPM-Listed Crops and Target Pests
| Crop | Label-Listed Pest Scope |
|---|---|
| Cotton | Bollworms, jassids and thrips |
| Rice (Paddy) | Leaf folder, stem borer, green leaf hopper, gall midge, rice hispa and thrips |
The physical label supplied with the pack is controlling. Do not extend these claims to another crop, pest, formulation or concentration.
Registered Dose, Water Volume and PHI
The values below are presented per hectare because that is how the current Government of India registered-use table states them. There is no universal millilitre-per-litre rate: spray concentration changes with the prescribed product rate and total spray-water volume.
| Crop | Active Ingredient | Product Rate | Water Volume | PHI |
|---|---|---|---|---|
| Cotton | 15–25 g a.i./ha | 300–500 ml/ha | 400–600 L/ha | 21 days |
| Rice (Paddy) | 12.5 g a.i./ha | 250 ml/ha | 400–600 L/ha | 15 days |
PHI means pre-harvest interval: the minimum waiting period between the final application and harvest. If the supplied label differs, stop and follow that label or obtain local agricultural guidance.
Application Best Practices
- Confirm the use: Match the crop and pest to the supplied label before opening the container. Apply when the pest reaches the locally recommended economic threshold.
- Measure accurately: Base the quantity on the labelled area rate. Calibrate the sprayer to deliver the specified total water volume with even coverage.
- Do not improvise a tank mix: Do not combine with another pesticide, fertilizer or adjuvant unless the supplied label and competent local guidance explicitly support it.
- Protect people: Wear label-required protective clothing while measuring, mixing and spraying. Avoid contact with skin, eyes and mouth, and avoid breathing spray mist.
- Protect non-target organisms: Lambda-Cyhalothrin is highly hazardous to aquatic organisms and bees. Prevent drift and runoff into water, and do not expose actively foraging bees.
- After use: Wash exposed skin and contaminated clothing, keep the product locked in its original labelled container, and dispose of the empty container exactly as the label and local rules require. Never reuse it.

HPM lists cotton and rice (paddy), with the specific pests shown in the crop table above. The supplied pack label controls the final use decision.
4. What is the dose per litre of water?
There is no single universal per-litre dose. Use the crop-specific product rate and total water volume on the supplied label; do not divide or transfer a rate from another formulation.
5. Can I replace a 2.5% EC or 4.9% CS product with this one at the same dose?
No. Different concentrations and formulation types are not dose-equivalent. Follow the exact label for the exact product in hand.
6. Can it be mixed with another pesticide?
