Nurocombi Insecticide (FMC): The Powerful '505' Formula for Cotton & Rice
Get double protection with the synergistic power of Chlorpyrifos 50% and Cypermethrin 5%.
Nurocombi by FMC India is a market-leading broad-spectrum insecticide, popularly known as the "505" formulation. It is designed to fight tough mixed infestations of sucking and chewing pests. By combining two powerful active ingredients, it provides an immediate "knockdown" of pests while ensuring long-lasting residual protection for your crops.
Best For: Farmers dealing with complex pest attacks (Bollworms, Borers, and Sucking pests) simultaneously in Cotton, Rice, and Vegetables.
Why Choose This Product? Key Benefits
- ⏱️Instant Knockdown Power: The Cypermethrin component acts immediately upon contact, stopping the pest from feeding and damaging the crop instantly.
- ?️Long-Lasting Residue: Chlorpyrifos remains on the foliage for weeks, creating a protective shield that prevents re-infestation.
- ⏳Dual Mode of Action: Attacks the insect nervous system in two different ways (Systemic & Contact), making it highly effective even against resistant pests.
- ?️Vapor Action Technology: The formulation creates a vapor that penetrates dense canopies to kill hidden pests (like larvae inside cotton bolls) that sprays miss.
- ?Versatile Crop Protection: One solution for multiple crops including Cotton, Paddy (Rice), Brinjal, and Cabbage.

How It Works: Mode of Action
Nurocombi uses a "Double Engine" approach to destroy the insect's nervous system. It works through both Contact and Vapor action.
- Systemic Enzyme Inhibition (Chlorpyrifos): It enters the insect body and inhibits the Acetylcholinesterase (AChE) enzyme. This causes a "cholinergic crisis," leading to paralysis.
- Nerve Channel Modulation (Cypermethrin): It attacks the sodium channels in the nerve cells, causing the nerves to fire repeatedly without stopping. This leads to immediate hyperexcitability and knockdown.
- Synergistic Attack: The combination ensures that even if a pest has some resistance to one chemical, the other one finishes the job.
Result: Total nervous system failure of the pest within minutes of application.

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) |
|---|---|---|---|---|
| Cotton | 600 ml | 200 - 300 L | 2 - 3 ml | 15-21* |
| Rice (Paddy) | 250 - 300 ml | 200 L | 1.5 ml | 15* |
| Vegetables | 300 - 600 ml | 200 L | 1.5 - 3 ml | 7-14* |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. *Refer to the official product leaflet for exact PHI days per crop.
How to Apply: Best Practices
- Timing: Apply at the first sign of pest infestation. For Bollworms, spray during the egg-laying or early larval stage.
- Mixing: Add the required quantity of Nurocombi to a little water, stir well to form a milky white emulsion, then add the remaining water.
- Coverage: Ensure thorough coverage of the foliage, especially the undersides of leaves where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not induce vomiting if swallowed (contains solvents).
Frequently Asked Questions
1. What is the difference between Nurocombi and Nurokind?
CRITICAL: Nurocombi is a POISONOUS INSECTICIDE for crops. "Nurokind" is a human medicine (Vitamin). Never confuse the two. Keep Nurocombi stored away from all medicines to prevent fatal accidents.
2. Is Nurocombi safe for fish and aquatic life?
No. Nurocombi is highly toxic to fish, crabs, and aquatic organisms. Do not use near fish ponds or let run-off water enter water bodies.
3. Can I use this for household bugs?
Absolutely not. This is a high-strength agricultural pesticide meant only for field crops (Cotton/Rice). Using it indoors is dangerous to human health.
4. What is the antidote for accidental poisoning?
For Chlorpyrifos poisoning, the antidote is Atropine Sulfate and 2-PAM (administered by a doctor). There is no specific antidote for Cypermethrin; treatment is symptomatic.
5. Why is it called "505"?
"505" refers to the percentage of active ingredients: 50% Chlorpyrifos and 5% Cypermethrin.
