Nichino Melt Fungicide (Isoprothiolane 40% EC)
The Dual-Action Specialist for Rice Blast Control and Root Health.
Melt (Isoprothiolane 40% EC) by Nichino India is a world-class systemic fungicide designed specifically for paddy farmers. It doesn't just cure diseases; it acts as a health booster for your crop. By controlling all stages of Rice Blast and simultaneously suppressing Brown Plant Hoppers (BPH), Melt ensures your harvest stays safe and your yields remain high.
Best For: Controlling Leaf Blast, Neck Blast, and improving root growth in Paddy.
Why Choose This Product? Key Benefits
- ⏱️Rapid Systemic Action: Absorbed quickly by leaves and roots, moving throughout the plant to protect new growth immediately.
- ?️Complete Blast Protection: Effectively prevents and cures Leaf Blast, Node Blast, and the devastating Neck Blast.
- ⏳Dual-Pest Control: Unlike standard fungicides, Melt also suppresses Brown Plant Hopper (BPH) populations, reducing the need for extra sprays.
- ?️Excellent Rainfastness: Absorbs into the plant system within 1-2 hours, ensuring performance even during monsoon rains.
- ?Phytotonic "Greening" Effect: Stimulates white root growth and delays leaf drying, leading to better grain filling and higher yields.

How It Works: Mode of Action
Melt works in a unique way to stop the fungus before it damages the plant. It operates on two levels:
[Image of isoprothiolane mode of action diagram]- Starves the Fungus: It inhibits phospholipid biosynthesis. Simply put, it stops the fungus from building its cell walls, causing it to collapse and die.
- Prevents Penetration: Even if a spore lands on the leaf, Melt prevents it from forming the "infection peg" (the needle used to pierce the leaf), stopping the disease from entering the plant.
- Systemic Shield: Once sprayed, it travels Up (to the panicle) and Down (to the roots), creating a full-body shield for the rice plant.
Note: This unique action makes it excellent for preventing resistance when rotated with other fungicides.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Leaf Blast, Neck Blast, Node Blast |
| Paddy (Rice) | Brown Plant Hopper (Suppression) |
| Paddy (Rice) | Akiochi Disease (Root Rot) |
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) |
|---|---|---|---|---|
| Paddy (Rice) | 300 ml | 200 Litres | 1.5 ml | 60 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 primarily during the Tillering Stage (Preventive) or the Booting Stage (Just before panicle emerges). Avoid spraying too close to harvest due to the 60-day PHI.
- Mixing: Melt is compatible with most insecticides like Cartap or Coragen. However, do not mix with alkaline substances like Bordeaux mixture.
- Coverage: Use a minimum of 200 liters of water per acre. Ensure the spray reaches the lower stems and neck area for maximum protection.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds as it is toxic to fish.
Frequently Asked Questions
1. Does Melt only kill fungus?
No. While it is primarily a fungicide for Blast, it also suppresses Brown Plant Hoppers (BPH) and stimulates root growth, improving overall plant health.
2. Can I use Melt to control Neck Blast?
Yes, Melt is excellent for Neck Blast. For best results, spray at the "Booting" stage (when the pregnant plant is swollen) before the panicle comes out.
3. What is the benefit of Melt on roots?
Melt helps recover plants from "Akiochi" (root rot) caused by soil stress. It promotes the growth of white, healthy roots, allowing better nutrient uptake.
4. Is it rainfast?
Yes, Melt is an EC formulation that penetrates the leaf quickly. It is considered rainfast within 1 to 2 hours of application.
5. Can I use it on Basmati rice for export?
Use with caution. Because Melt has a 60-day waiting period (PHI), it should only be used in the early stages (Tillering/Booting). Do not use it in the late milky stage for export crops to avoid residue issues.
