How It Works: Mode of Action
Krishan targets the insect's nervous system by inhibiting an enzyme called Acetylcholinesterase (AChE). This causes paralysis and eventual death of the pest.
- Contact Action: Pests die immediately when the spray droplets hit their body or when they walk over treated surfaces.
- Stomach Action: Ideal for chewing pests (like caterpillars); they are poisoned when they eat leaves treated with Krishan.
- Vapor (Fumigant) Action: The chemical releases strong vapors that penetrate dense crop canopies and soil cracks, reaching hidden pests like aphids and termites.
Note: While it has strong vapor action, it is non-systemic, so good coverage 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) |
|---|---|---|---|---|
| Paddy | 500 ml | 200 L | 2.5 ml | 30 |
| Cotton | 500 ml | 200 L | 2.5 ml | 15-30 |
| Brinjal | 400 - 600 ml | 200 L | 2 - 3 ml | 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the first sign of pest activity (Economic Threshold Level). For stem borers, apply when you see 5-10% dead hearts.
- Mixing: Premix the required quantity of Krishan with a small amount of water before adding it to the main spray tank.
- Coverage: Ensure thorough coverage of both upper and lower leaf surfaces. For termites, saturate the soil completely.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during strong winds.
Frequently Asked Questions
1. How do I use Krishan for termites in construction?
Mix 1 Liter of Krishan with 19 Liters of water (1:19 ratio) for a 1% concentration. Pour this solution into foundation pits and drilled holes along walls.
2. Is Krishan a systemic insecticide?
Technically, it is non-systemic (Contact & Stomach action). However, its strong vapor action allows it to penetrate hidden areas, mimicking systemic reach.
3. Can I mix Krishan with other pesticides?
Yes, it is often mixed with Cypermethrin or Acetamiprid for a broader "knockdown" effect against mixed pest populations. Always perform a physical compatibility test first.
4. Is it safe for aquaculture/fish farming?
No. Chlorpyriphos is highly toxic to fish. Do not use it in paddy fields connected to fish ponds or near water bodies.
5. What is the antidote in case of accidental poisoning?
The specific antidotes are Atropine Sulphate and 2-PAM. Immediate medical attention is required.
