Why Farmers Choose Catchh? Key Benefits
-
⏱️
Instant Knockdown Power: The Cypermethrin component attacks the pest's nervous system immediately upon contact, stopping crop damage instantly.
-
🛡️
Dual-Action Resistance Breaker: Combines contact, stomach, and vapor action to kill pests that have developed resistance to single-chemical sprays.
-
⏳
Long-Lasting Protection: Remains active on the leaf surface for 10–15 days, providing extended security against re-infestation.
-
🌧️
Excellent Rainfastness: Absorbs quickly into the plant system; effectively rainfast within 2–4 hours after application.
-
🌿
Reaches Hidden Pests: The strong vapor action (fumigation effect) penetrates hidden areas like curled leaves and cotton bolls to reach pests hiding inside.

Mode of Action: How It Kills Pests
Catchh uses a synergistic "Double Engine" mechanism to ensure high mortality rates in pests:
- Nervous System Overload (Synaptic): Chlorpyrifos inhibits the enzyme Acetylcholinesterase (AChE), causing continuous nerve firing, paralysis, and death.
- Instant Shock (Axonic): Cypermethrin keeps the sodium channels open in the insect's nerves, causing immediate spasms and "knockdown" (falling off the plant).
- Synergism (Potentiation): The Chlorpyrifos prevents the insect from detoxifying the Cypermethrin, making the mixture significantly more lethal than either chemical alone.
This combination works via Contact (touch), Stomach (ingestion), and Vapor (breathing) action.

Catchh Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results to avoid resistance and residue issues.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 400 - 500 ml | 200 - 400 L | ~1.5 - 2.5 ml | 15 Days |
| Paddy (Rice) | 250 - 300 ml | 200 - 300 L | ~1.5 ml | 15-30 Days |
| Vegetables | 250 - 400 ml | 150 - 200 L | ~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 population reaches the Economic Threshold Level (ETL) (e.g., 5% damage in cotton).
- Mixing: Add the required quantity of Catchh to a small amount of water, mix well to form a white emulsion, then add the remaining water.
- Coverage: Ensure complete foliage coverage. For Stem Borers and Leaf Folders, ensure the spray reaches the base of the plant.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use during flowering stage (toxic to bees).
Frequently Asked Questions
1. Can Catchh be used on Basmati Rice?
No. Due to strict export residue limits (MRLs) and trade restrictions in states like Punjab, it is recommended to avoid using Chlorpyrifos-based products on Basmati rice meant for export.
2. How does Catchh compare to pure Cypermethrin?
Catchh is superior because the added Chlorpyrifos prevents pests from detoxifying the Cypermethrin. This makes it effective even against pests that have developed resistance to plain synthetic pyrethroids.
3. Is Catchh effective against Whiteflies?
Yes, it provides reasonable control. However, for heavy Whitefly infestations, specific sucking pest remedies might be required alongside it.
4. What is the antidote for accidental poisoning?
The specific antidote is Atropine Sulphate and 2-PAM (Pralidoxime). Immediate medical attention is required.
5. Can I use this product in Kerala?
No. The sale and use of Chlorpyrifos + Cypermethrin combinations are currently banned in the state of Kerala due to environmental regulations.
