How It Works: Mode of Action
Cyperhit-25 targets the nervous system of the insect. It is an axonic poison that disrupts normal nerve transmission. [Image of nerve synapse sodium channel]
- Contact & Entry: The chemical enters the pest through direct contact or ingestion of treated leaves.
- Nerve Disruption: It binds to sodium channels in the nerve cells, keeping them open and causing a massive influx of ions ($Na^+$).
- Paralysis & Elimination: This causes hyperexcitation and tremors, quickly leading to paralysis and death of the pest.
This mechanism ensures that pests stop damaging your crop almost immediately after spraying.
Target Crops & Pests
| Crop | Target Pest(s) |

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 | 240 - 320 ml | 160 - 300 L | 1.5 - 2 ml | - |
| Brinjal | 80 - 120 ml | 200 L | 0.5 - 1 ml | 1 Day |
| Okra / Vegetables | 100 - 200 ml | 200 L | 0.5 - 1 ml | 3 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the first sign of pest incidence (e.g., square formation in cotton). Avoid spraying during active bee foraging hours (morning).
- Mixing: Pour the required quantity into water and stir well to form a white emulsion. It can be tank-mixed with other fungicides, but avoid indiscriminate mixing to prevent resistance.
- Coverage: Ensure thorough coverage of foliage, especially the underside of leaves where Jassids and eggs often reside.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Symptoms like facial tingling are common if skin contact occurs.

Yes, it is generally compatible with common fungicides and insecticides like Ethion. However, do not mix with highly alkaline substances (like Lime Sulphur).
5. Does it kill beneficial insects?
Cypermethrin is toxic to bees and fish. Do not spray near water bodies (ponds/rivers) and avoid spraying when bees are actively pollinating the crop.
