How It Works: Mode of Action
Tatafen acts as a broad-spectrum neurotoxin. It disrupts the insect's nervous system by targeting the voltage-gated sodium channels.
[Image of insect nervous system sodium channel blockage]- Double Entry: It enters the pest via Contact (touching treated leaves) and Stomach action (eating treated foliage).
- Nervous Overload: Once inside, it keeps the insect's nerve channels open, causing repetitive nerve impulses.
- Immediate Paralysis: This leads to extreme agitation, followed rapidly by paralysis and death. The pest stops feeding instantly.
Note: This product is non-systemic, so good coverage of the plant surface 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 | 300 – 500 ml | 200 – 300 L | 2.0 – 2.5 ml | 7 – 15 Days |

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Start spraying when pest damage reaches the Economic Threshold Level (e.g., 5% damage). Evening spraying is best to avoid heat and protect bees.
- Mixing: Ensure adequate water volume (approx. 200 liters per acre) to get thorough coverage, as this is a contact insecticide.
- Coverage: Focus on covering the undersides of leaves and developing fruits/bolls where larvae hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid skin contact to prevent itching (paresthesia).
