| Brand Name | Nayak |
| Technical Name | Alpha-cypermethrin 10% EC |

How It Works: Mode of Action
Nayak works by disrupting the nervous system of the insect. As a Type II Pyrethroid, it is much stronger than older chemicals like Cypermethrin.
- Contact & Entry: The chemical penetrates the insect's outer skin (cuticle) immediately upon spraying.
- Nerve Paralysis: It binds to sodium channels in the nerves, keeping them open. This causes uncontrolled spasms and tremors in the insect.
- Elimination: The insect loses coordination, stops eating (Anti-feedant action), and dies due to paralysis and starvation.
Note: Nayak is a non-systemic contact poison. It does not travel inside the plant, so good spray coverage is essential.

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 | 100 - 110 ml | 200 L | 0.5 - 0.6 ml | 7 |
| Rice (Paddy) | 100 - 120 ml | 200 L | 0.6 ml | 15 |
| Vegetables | 80 - 100 ml | 200 L | 0.5 ml | 3 - 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when you first see the pest or when egg-hatching begins. Evening sprays are best to avoid harming honeybees.
- Mixing: Nayak mixes easily with water to form a white emulsion. Do NOT mix with alkaline products like Bordeaux mixture or Lime Sulfur.
- Coverage: Since it is a contact poison, ensure you spray the undersides of leaves where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling the spray mist.
Frequently Asked Questions
1. Is Nayak effective against Pink Bollworm?
Yes, Nayak is effective against adult moths and young larvae moving on the surface. However, it cannot kill larvae that have already bored deep inside the boll.

The price generally ranges between ₹280 to ₹600 depending on the retailer and bulk discounts, making it a very economical choice (approx ₹40/acre).
