IFFCO-MC Yuri Insecticide (Lambda-cyhalothrin 4.9% CS)
Advanced "Smart Capsule" Technology for Long-Lasting Control of Bollworms, Borers, and Sucking Pests.
Yuri is a premium insecticide brought to you by the joint venture of IFFCO and Mitsubishi Corporation. Unlike older liquid sprays (EC), Yuri uses advanced Capsule Suspension (CS) technology. The active ingredient is locked inside microscopic shells that protect it from sunlight and heat, releasing the medicine only when the pest touches the leaf. This ensures powerful control over caterpillars and beetles with better safety for the farmer.
Best For: Cotton, Paddy, Vegetables (Brinjal, Okra, Tomato, Chilli), and Grapes.
Why Choose This Product? Key Benefits
-
⏱️
Double Action Power: Kills pests on contact (Knockdown) and if they eat the leaf (Stomach action). It also repels pests from laying eggs.
-
🛡️
Smart Encapsulation: The active chemical is protected inside tiny capsules. This prevents it from evaporating in the sun, giving you longer results than standard EC sprays.
-
⏳
Short Wait Period (PHI): Safe for vegetable farmers. For crops like Brinjal, Okra, and Tomato, you can harvest just 5 days after spraying.
-
🌧️
Rainfast Technology: The capsules stick firmly to the leaf surface. It becomes resistant to rain wash-off within 2-4 hours of application.
-
🌿
Crop Safe (No Burning): Being water-based (CS formulation) without harsh solvents like Xylene, it does not burn tender leaves or flowers like some EC products do.

How It Works: Mode of Action
Yuri works by attacking the nervous system of the insect. It is a "Sodium Channel Modulator."
- Controlled Release: The Lambda-cyhalothrin is hidden inside micro-capsules. When the spray dries on the leaf, these capsules sit like "landmines."
- Contact Trigger: When an insect walks over the leaf, the capsules burst open, delivering a pure dose of the chemical directly to the insect's body.
- Nervous System Shutdown: The chemical rapidly enters the insect's nerves, causing over-excitement (tremors), followed by paralysis (knockdown), and finally death.
Note: Yuri also acts as a repellent, discouraging moths from laying eggs on treated crops.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Bollworm Complex (American, Spotted, Pink Bollworm), Jassids, Thrips |

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 | 500 ml | 500 L | 1 ml | 21 Days |
| Paddy (Rice) | 250 - 300 ml | 500 L | 0.5 - 0.6 ml | 15 Days |
| Brinjal / Okra / Tomato | 300 ml | 500 L | 0.6 ml | 5 Days |
| Grapes | 250 ml | 500 - 1000 L | 0.25 - 0.5 ml | 7 Days |
| Soybean | 300 ml | 500 L | 0.6 ml | 31 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure residues are safe.
How to Apply: Best Practices
- Timing: Apply when you first see pest damage (ETL levels) or eggs. For Cotton and Paddy, mid-season application is best.
- Mixing: Fill the tank halfway with water, add the required dose of Yuri, stir well, and then fill the rest. Avoid mixing with highly alkaline products like Bordeaux mixture.
- Coverage: Use a Hollow Cone Nozzle. Ensure the spray covers the undersides of leaves where insects hide. Use sufficient water (500 L/acre) for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray near fish ponds.
Frequently Asked Questions
1. Why is the CS formulation better than EC?
CS (Capsule Suspension) is safer and lasts longer. The micro-capsules protect the chemical from the sun, giving you extended control (residual activity) compared to liquid ECs which can evaporate quickly.
2. Will rain wash Yuri off the leaves?
No, Yuri has excellent rainfastness. Once the spray dries (usually 2-4 hours), the capsules stick to the leaf and resist being washed away by light to moderate rain.
3. Can I use Yuri on vegetable crops?
Yes, it is excellent for Brinjal, Okra, and Tomato. It has a short waiting period (PHI) of just 5 days, making it safe for crops that are harvested frequently.
4. Does it kill eggs (Ovicidal action)?
While primarily a larvicide (kills worms) and adulticide (kills beetles), Yuri has strong repellent properties that prevent moths from laying eggs on the treated area.
5. Is it safe for the person spraying?
Yuri is safer than old-fashioned EC sprays because the chemical is encapsulated. However, it is a Blue Label product, so standard safety gear (mask and gloves) is mandatory to prevent skin irritation.
