How It Works: Mode of Action
Lethal Gold uses a "Double-Tap" strategy to ensure pests cannot survive. It targets the insect's nervous system at two different points.
- The Paralyzer (Bifenthrin): It keeps the sodium channels in the insect's nerves open. This causes the insect to shake uncontrollably, lose coordination, and stop feeding instantly.
- The Terminator (Chlorpyriphos): It blocks a vital enzyme called Acetylcholinesterase (AChE). This causes a "signal jam" in the brain, leading to total system failure and death.
- The Fumigant Effect: The vapors from Chlorpyriphos enter tiny holes in plant stems, killing larvae hiding inside (like Stem Borers) that regular sprays cannot reach.
Result: A nearly 100% kill rate, even for pests that have grown resistant to other simple sprays.

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) |
|---|---|---|---|---|
| Rice (Paddy) | 400 ml | 150 - 200 L | 2.0 - 2.5 ml | 15 Days |
| Cotton | 400 - 500 ml | 150 - 200 L | 2.5 ml | 15 Days |
| Sugarcane | 500 ml (Drench) | 300 - 400 L | 1.5 - 2.0 ml | 30 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 during the early morning or late evening. Avoid spraying at noon when bees are active.
- Mixing: Do not mix with alkaline chemicals like Bordeaux Mixture or Lime Sulfur, as they reduce efficacy. Compatible with most fungicides like Hexaconazole.
- Coverage: Ensure full coverage of the foliage. For Stem Borers, direct the nozzle toward the base of the plant.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This product is highly toxic to fish; do not use near ponds.
Frequently Asked Questions
1. Does Lethal Gold control mites?
Yes. The Bifenthrin component provides excellent control against mites (acaricidal action) alongside killing insects.
2. Can I use Lethal Gold for termites in buildings?
While it contains termiticides, this specific agricultural formulation is designed for crops. Please refer to specific household pest control products for building safety.
3. Is it safe for vegetable crops?
It is effective, but because it leaves a residue, it should only be used in the early vegetative stage. Avoid using it near harvest time to ensure food safety.
4. What is the difference between Lethal Super and Lethal Gold?
Lethal Super uses Cypermethrin, whereas Lethal Gold uses Bifenthrin. Lethal Gold is generally superior for longer protection and better control of mites.
5. How fast does it work?
You will see pests stop feeding and become paralyzed within minutes of spraying. Full mortality usually occurs within 24 hours.
