How It Works: Mode of Action
Reeva 2.5 attacks the pest's nervous system. It triggers the sodium channels in nerve cells to stay open, causing continuous nerve firing.
- Hyperexcitation: The insect gets the "jitters," loses coordination, and comes out of hiding (flushing effect).
- Paralysis: Within minutes, the pest stops feeding and becomes paralyzed.
- Elimination: The pest dies due to starvation and nervous system failure.
It also acts as an Anti-feedant, meaning insects stop damaging the crop almost immediately after sensing the chemical.

Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 200 - 330 ml | 150 - 200 L | 2.0 - 2.5 ml | 21 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 in the late evening to protect honeybees and pollinators (Reeva is toxic to bees).
- Mixing: Do NOT mix with alkaline substances like Bordeaux mixture or Lime Sulfur, as this neutralizes the poison.
- Coverage: Use a Hollow Cone Nozzle to create a fine mist that covers the underside of leaves where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid skin contact to prevent burning sensations.
Frequently Asked Questions
1. Does Reeva 2.5 control sucking pests like Jassids?
Yes, it has excellent contact action against sucking pests (Jassids, Thrips, Hoppers), providing relief from "hopper burn."
2. It caused a burning sensation on my skin. What should I do?
This is a common reaction to pyrethroids called paresthesia. It is temporary. Do not scrub the skin. Apply Vitamin E oil or cool compresses to soothe it. Always wear gloves.
3. Can I use Reeva 2.5 on fish ponds?
No. Lambda-cyhalothrin is highly toxic to fish and aquatic life. Do not spray near water bodies.
4. Is it rainfast?
Yes, Reeva 2.5 is generally rainfast within 2 to 4 hours after application.
5. How does it help with resistance management?
Reeva 2.5 is a cost-effective rotation partner. However, do not use it continuously. Rotate with other chemical groups (like Spinosad or Diamides) to prevent pests from becoming resistant.
