Attacks the insect's nervous system in two different ways, making it effective even against resistant Bollworms. - ?️Vapor Action for Hidden Pests:
Releases a gas vapor that penetrates inside cotton bolls and folded rice leaves to kill hidden larvae. - ?Broad Spectrum Control:
One spray controls caterpillars, sucking pests (aphids/jassids), and soil pests like termites simultaneously.

How It Works: Mode of Action
Lethal Super 505 attacks the insect's nervous system from multiple angles, ensuring a high kill rate.
- Contact & Stomach Action: Pests die immediately upon touching the spray or eating the treated leaves.
- Systemic & Translaminar Movement: The medicine penetrates the leaf tissue to kill sucking pests hiding on the underside of leaves.
- Vapor/Fumigant Action: It creates a gas phase that enters the respiratory system (spiracles) of pests hiding inside fruit bolls or folded leaves.
Note: The combination stops insects from feeding instantly, preventing further crop loss.

Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 ml | 200 Litres | 2.0 ml | 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: Apply when pest populations reach the Economic Threshold Level (ETL). Avoid spraying during peak flowering to protect bees.
- Mixing: Pour the required dose into a bucket of water, stir well to form a white emulsion, then add to the spray tank.
- Coverage: Use a hollow cone nozzle for fine mist. Ensure the underside of leaves and stems are thoroughly wetted.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use near fish ponds.
