Its advanced formula resists sunlight degradation, ensuring your crop stays protected for longer, even days after spraying.
Best For: Cotton, Brinjal, Cauliflower, Okra, and termite control in buildings.
Why Choose This Product? Key Benefits

Unlike older sprays, Tatafen is UV-stable (photostable), meaning sunlight does not destroy it quickly. - ?️Excellent Leaf Coverage:
The EC formulation sticks well to plant surfaces and penetrates the waxy layers of leaves and pests. - ?Economical for Farmers:
Provides high-quality pest control at a very affordable price point (approx. ₹800–₹900 per Litre).

How It Works: Mode of Action
Tatafen acts as a nerve poison for insects. It targets the nervous system of the pest, specifically the sodium channels.
- Entry: The chemical enters the pest through direct contact (spray droplets) or ingestion (eating treated leaves).
- Blockage: It binds to the nerve cells and keeps the sodium channels "open" continuously.
- Knockdown: This causes extreme excitement and tremors in the pest, followed rapidly by paralysis and death.
Note: This is a non-systemic product. It stays on the surface of the plant to create a protective barrier.

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 | 300 – 500 ml | 200 – 300 L | 2.0 – 2.5 ml | 7 – 15 Days |
| Cauliflower | 300 – 375 ml | 200 L | 1.5 – 2.0 ml | 7 Days |
| Brinjal & Okra | 300 – 500 ml | 200 L | 1.5 – 2.5 ml | 7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when pest population reaches the Economic Threshold Level (e.g., 5% damage). Apply in the cool evening hours to avoid harming honey bees.
- Mixing: Use clean water. Add the required quantity of Tatafen to a small amount of water first to make a solution, then add to the main tank.
- Coverage: Ensure full coverage of the foliage. Since this is not a systemic medicine, it must cover the leaves/fruits where the pest sits.
- Safety: Always wear PPE (gloves, mask, goggles). This product can cause temporary skin itching/tingling (paresthesia) if it touches bare skin. Wash hands thoroughly after use.
