Syngenta Reflect Top Fungicide: The Sheath Blight Specialist
Experience the power of "Double Binding Technology" for unmatched protection against Rice Sheath Blight.
Reflect Top is a next-generation fungicide that combines the potency of Isopyrazam (SDHI) with the reliability of Difenoconazole (Triazole). It is engineered specifically to lock onto fungal pathogens and provide a long-lasting shield, ensuring your rice crop stays healthy from the booting stage through to harvest.
Best For: Farmers seeking a proactive, rainfast solution to protect the critical flag leaf and maximize grain filling in rice.
Why Choose This Product? Key Benefits
-
⏱️
Long-Lasting Protection: Provides an extended defense shield for 15–20 days, reducing the labor and cost of frequent re-spraying.
-
🛡️
Double Binding Technology: The active molecule "locks" onto the fungus with dual anchors, making it incredibly difficult for the disease to survive.
-
⏳
Curative & Preventive: It doesn't just prevent disease; it provides a "kick-back" effect to stop existing infections and protects new growth.
-
🌧️
Superior Rainfastness: The lipophilic formula binds rapidly to the leaf wax within 1-2 hours, making it weather-proof against the Indian monsoon.
-
🌿
Green Flag Leaf: Keeps the flag leaf green and functional, which is essential for maximum carbohydrate transport and heavier grains.

How It Works: Mode of Action
Reflect Top operates using a unique dual-action mechanism that attacks the fungus on two fronts, ensuring resistance management and high efficacy.
- Energy Blockade (Isopyrazam): It inhibits the Succinate Dehydrogenase enzyme in the fungus's mitochondria. This cuts off the energy supply (ATP), effectively starving the fungus.
- The Wax Reservoir Effect: Isopyrazam loves plant wax (lipophilic). It creates a depot in the leaf surface that releases the medicine slowly over time, providing weather-proof protection.
- Systemic Flow (Difenoconazole): This component enters the plant and moves upwards (acropetally), protecting new growth and destroying fungal cell membranes.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Sheath Blight (Rhizoctonia solani) |
| Rice (Secondary) | Dirty Panicle / Grain Discoloration |
| Other Crops | Refer to official label for regional approvals |
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) |
|---|---|---|---|---|
| Rice | Refer to Label | 200 Litres | ~1 ml/L | ~25 Days |
| Wheat | Refer to Label | 200 Litres | ~1 ml/L | Refer to Label |
| Vegetables | Refer to Label | 200 Litres | ~1 ml/L | Refer to Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Exact dosage may vary by local regulations; please verify the package leaflet.
How to Apply: Best Practices
- Timing: Apply at the Booting Stage (45-55 days after transplanting). This is the "Zero Tolerance" window to keep the flag leaf clean.
- Mixing: Do not mix with other Group 7 (SDHI) fungicides to prevent resistance. Rotational partners like Kavach (Group M5) are recommended.
- Coverage: Ensure the spray reaches the lower sheath where the infection starts, as well as the upper leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between Reflect Top and Amistar Top?
Reflect Top is a specialist for Sheath Blight, designed for high disease pressure and rainfastness. Amistar Top is a generalist "Panicle Protectant" that controls a wider mix of diseases and provides a cosmetic "shining" effect on the grain.
2. Is Reflect Top rainfast?
Yes. Due to the lipophilic (fat-loving) nature of Isopyrazam, it binds to the leaf wax within 1 to 2 hours, making it highly resistant to wash-off during monsoons.
3. Can I use Reflect Top twice in a row?
No. To prevent resistance, you should rotate chemical groups. Use Reflect Top (Group 7), then follow up with a different group like Kavach (Group M5) or Amistar Top (Group 11).
4. Which stage is best for application in Rice?
The best time is the Booting Stage. Protecting the crop here ensures the flag leaf remains healthy, which is directly responsible for filling the grains.
5. Does it help with grain quality?
Yes. By preventing Sheath Blight from reaching the upper leaves, Reflect Top prevents "chaffy" grains and ensures better grain weight and quality.
