Product scienceHow It Works: Mode of Action
Simha targets the nervous system of the insect. It is a "Sodium Channel Modulator."
- Contact & Entry: The chemical penetrates the waxy cuticle of the insect or is ingested.
- Over-Excitation: It jams the sodium channels in the nerve cells open. This causes the nerves to fire uncontrollably.
- Paralysis & Death: The insect experiences tremors ("jitter effect"), stops feeding, becomes paralyzed, and dies rapidly.
Note: It also has a repellent effect, discouraging new pests from entering the treated area.

How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 200 ml | 200 L | 1.0 ml | 21 Days |

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply: Best Practices
- Timing: Spray at the first sign of pest incidence. For bollworms, target the egg-hatching stage for maximum kill.
- Mixing: Ensure water pH is between 5.5 and 7.0. Do not mix with highly alkaline products like Bordeaux mixture.
- Coverage: Simha is a contact poison; thorough coverage of the plant canopy (including the underside of leaves) is critical.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid skin contact to prevent burning sensations.

Frequently Asked Questions
1. Is Simha systemic?
No, Simha is non-systemic. It works via contact and stomach action. However, it has translaminar properties (penetrates the leaf to kill pests on the underside).
2. Can I use Simha in paddy fields near fish ponds?
No. Lambda-cyhalothrin is highly toxic to fish and aquatic life. Avoid using it where runoff water can enter fish ponds.
3. Does it kill mites?
Simha suppresses mite populations (like Yellow Mites in chilli) but is primarily an insecticide. For severe mite infestations, use a dedicated acaricide.
4. What if I feel a burning sensation on my face after spraying?
This is a common temporary effect called Paraesthesia. Do not use water (it drives the chemical deeper). Apply Vitamin E oil or vegetable oil to soothe the skin. It usually resolves in 24 hours.
5. How does it help with resistance management?
It is a Group 3A insecticide. To prevent resistance, rotate Simha with other groups (like Organophosphates or Diamides) and do not use it for every single spray.
