Orchestra Duet Insecticide: Ultimate Protection Against BPH in Rice
Stop Hopper Burn and Protect Your Yields with Dual-Action Japanese Technology.
Indian rice farmers face a constant threat from the Brown Plant Hopper (BPH), a pest that can destroy entire crops through "hopper burn." Orchestra Duet by Nichino India is a revolutionary solution designed to solve this crisis.
Orchestra Duet combines two powerful active ingredients—Benzpyrimoxan and Pymetrozine—to provide immediate relief and long-lasting control. It stops pests from feeding instantly while breaking their reproductive cycle, ensuring your paddy stays healthy and green.
Why Choose This Product? Key Benefits
-
⏱️
Stops Feeding Instantly: The "Lock-Jaw" effect stops hoppers from sucking sap within 15-20 minutes, preventing viral transmission and hopper burn.
-
🛡️
Kills Resistant Pests: Effectively eliminates hoppers that have developed resistance to older chemicals like neonicotinoids and organophosphates.
-
⏳
Long-Lasting Protection: Provides up to 21 days of coverage, protecting the crop from the tillering stage through to panicle initiation with just one spray.
-
🌧️
Safe for Ecosystems: Highly selective formulation that kills pests but is safe for beneficial insects like spiders and mirid bugs (nature's pest controllers).
-
🌿
Phytotonic Effect: Beyond pest control, it promotes greener leaves, healthier tillers, and better grain filling for a superior harvest.

How It Works: Dual Mode of Action
Orchestra Duet uses a unique "Duet" synergy to attack pests on two fronts, making it nearly impossible for them to survive.
- Immediate Feeding Block (Pymetrozine): Upon contact, the pest's nervous system is tricked into thinking it is full. The insect withdraws its feeding tube instantly, preventing damage and starvation begins.
- Growth Disruption (Benzpyrimoxan): This novel IGR (Insect Growth Regulator) targets the nymphs. It stops them from molting (shedding skin). Trapped in their old skin, the nymphs die, preventing the next generation.
- Resistance Breaking: By combining these two different attack methods, Orchestra Duet effectively clears populations that survive other common pesticides.
This combination ensures that existing adults stop damaging the crop immediately, while the nymphs are killed off before they can mature.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Brown Plant Hopper (BPH) |
| Paddy (Rice) | White Backed Plant Hopper (WBPH) |
| Paddy (Rice) | Green Leaf Hopper (GLH) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Do not cut corners on water volume.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 280 g | 200 Liters | ~1.4 g | 21 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: The "3Rs" Best Practices
- Timing (Right Stage): Apply at the Max Tillering stage or when you see less than 8 hoppers per hill. Do not wait for a full outbreak.
- Mixing (Right Dose): Create a "stock solution" first by dissolving the granules in a small bucket of water before adding it to the main tank. This ensures the granules dissolve completely.
- Coverage (Right Method): BPH lives at the bottom of the plant. You must use 200 Liters of water per acre and direct the nozzle toward the base of the stems. Spraying only the top leaves will not work.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Orchestra Duet harm spiders in the field?
No. Orchestra Duet is highly selective. It targets hoppers but is safe for beneficial predators like spiders and mirid bugs, which helps maintain natural pest control.
2. How quickly will I see results?
The "stop-feeding" effect is immediate (15-20 minutes). While the pests may remain on the plant for a few days before falling off, they are no longer causing damage.
3. Can I use less than 200 Liters of water?
No. Using less water is the main cause of failure. The medicine must reach the water line/base of the plant where the BPH hides. Adequate water volume is essential for coverage.
4. Can this product control resistant BPH?
Yes. Benzpyrimoxan is a novel chemistry that works effectively against BPH populations that have developed resistance to older insecticides like Imidacloprid or Acephate.
5. What is the pack size available?
Orchestra Duet is typically available in a 280g pack, which is the exact calculated dose for one acre of paddy.
