Melt Fungicide (Isoprothiolane 40% EC) - Nichino | Complete Blast Control
A powerful systemic fungicide by Nichino India that controls Rice Blast while boosting root health and suppressing BPH.
Melt (Isoprothiolane 40% EC) is more than just a fungicide; it is a plant health booster. Designed specifically for Paddy (Rice), it provides dual protection against the devastating Blast fungus and the Brown Plant Hopper (BPH). Its unique "Phytotonic" effect helps regenerate roots, prevents "Akiochi" (root rot), and keeps leaves green for longer, ensuring a higher yield and better grain quality.
Best For: Farmers dealing with Leaf Blast, Neck Blast, or weak root systems in paddy fields.
Why Choose This Product? Key Benefits
-
⏱️
Systemic & Curative Action: Melt moves up and down inside the plant (Acropetal & Basipetal), curing existing infections and protecting new leaves.
-
🛡️
Triple Blast Protection: Effectively controls all stages of the disease: Leaf Blast, Node Blast, and the critical Neck Blast.
-
⏳
Phytotonic Root Booster: Stimulates new white root growth, helps plants recover from anaerobic soil stress (Akiochi), and delays leaf aging.
-
🌧️
Rainfast & BPH Suppression: Rapidly absorbed within 1-2 hours (Rainfast). Also suppresses Brown Plant Hopper populations, reducing the need for extra sprays.
-
🌿
Japanese Innovation: Manufactured by Nichino (Japan), ensuring high purity, stability, and superior results compared to generic alternatives.

How It Works: Mode of Action
Melt works on two fronts: it attacks the fungus and strengthens the plant.
- Cell Wall Destruction: It inhibits the fungus's ability to synthesize phospholipids (Choline), causing the fungal cell walls to collapse and the organism to die.
- Infection Blockade: It specifically stops the formation of "infection pegs," preventing the fungus from penetrating the rice leaf in the first place.
- Systemic Shield: Once sprayed, it enters the plant and travels to the leaf tips and roots, offering long-lasting internal protection.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Leaf Blast (Pyricularia oryzae) |
| Paddy (Rice) | Neck Blast & Node Blast |
| Paddy (Rice) | Brown Plant Hopper (Suppression) |
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. Note: Due to the 60-day PHI, Melt is best used in early stages (Tillering to Booting).
How to Apply: Best Practices
- Timing: Apply prophylactically (preventive) at the Tillering stage or immediately at the first sign of Leaf Blast. For Neck Blast, spray at the "Booting" stage (just before panicles emerge).
- Mixing: Compatible with most insecticides like Cartap or Coragen. Do not mix with highly alkaline products like Bordeaux mixture.
- Coverage: Use a minimum of 200 Litres of water per acre with a hollow cone nozzle to ensure the spray penetrates the canopy.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use near fish farms (Pisciculture).
Frequently Asked Questions
1. Does Melt kill Brown Plant Hoppers (BPH)?
Melt acts as a BPH suppressant. While it is primarily a fungicide, it reduces BPH populations and prevents resurgence, reducing the need for heavy insecticide use.
2. Can Melt cure Neck Blast?
Neck blast is very difficult to cure once it appears. Melt is highly effective against it if sprayed at the Booting stage (before the neck is exposed), acting as a systemic shield.
3. What is the waiting period (PHI) for Melt?
The Pre-Harvest Interval is 60 days. Do not spray this product if you plan to harvest the crop within the next two months.
4. How does Melt help root health?
Melt contains Isoprothiolane, which stimulates root elongation and helps plants recover from "Akiochi" (root rot caused by soil toxicity), improving nutrient uptake.
5. Is Melt rainfast?
Yes, Melt is an EC formulation that penetrates the leaf surface quickly. It is considered rainfast within 1 to 2 hours of application.
