Blightwar Fungicide (Validamycin 3% L) | The Sheath Blight Specialist
Stop Rice Sheath Blight and Soil-Borne Diseases with Japanese Antibiotic Technology.
Blightwar (by Nichino India) is a specialized antibiotic fungicide designed to fight the specific "Rhizoctonia" fungus. Unlike harsh chemicals that burn the plant, Blightwar works by "starving" the fungus, stopping it from spreading up the rice stem. It is the most cost-effective and safe solution for protecting your yield during the critical tillering and booting stages.
Best For: Rice (Paddy), Potato, and Vegetable Nurseries.
Why Choose This Product? Key Benefits
- ⏱️Stops Disease Instantly: Effectively freezes the "runner hyphae" (fungal threads), preventing the disease from reaching the flag leaf.
- ?️Resistance Breaker: Ideal for rotation. Works perfectly when other fungicides (like Azoxystrobin or Hexaconazole) start losing effectiveness.
- ⏳Long-Term Control: Not only stops the current infection but also reduces the viability of fungal spores (sclerotia) for the next season.
- ?️Rainfast & Absorbed: Quickly absorbed by the leaves (Translaminar action), so it doesn't wash off easily during monsoon rains.
- ?Eco-Friendly & Safe: Safe for farmers, fish, and beneficial insects (like bees and spiders). Does not harm the rice plant.

How It Works: Mode of Action
Blightwar uses a unique mechanism called "Metabolic Starvation." It does not kill the fungus by poison, but by blocking its energy supply.
[Image of Validamycin mechanism of action diagram]- Entry: The antibiotic penetrates the fungal hyphae immediately upon contact.
- Blockade: It inhibits the enzyme Trehalase. This enzyme is responsible for turning the fungus's stored sugars (Trehalose) into usable energy (Glucose).
- Starvation: Without energy, the fungus stops growing, the lesions dry up, and the infection effectively stops spreading.
Result: The disease is "frozen" in place, allowing the plant to recover and fill grains.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Sheath Blight (Rhizoctonia solani) |
| Potato | Black Scurf (Seed/Soil treatment) |
| Vegetables (Tomato/Brinjal) | Damping Off (Soil borne) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. High water volume is critical for Sheath Blight control.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 400 - 500 ml | 150 - 200 L | 2.5 ml | 14 |
| Potato (Tubers) | Seed Treatment | N/A | 2.5 - 3 ml | 14 |
| Veg Nurseries | Soil Drench | As Needed | 2.5 ml | 14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply immediately when you see the first symptoms (greenish-grey spots at the water line) or during the Max Tillering/Booting stage.
- Mixing: Compatible with most insecticides (Cartap, Flubendiamide) and fungicides (Propiconazole). Do NOT mix with Bordeaux mixture or Lime Sulfur (Alkaline).
- Coverage: Use plenty of water (min 150L/acre). Direct the nozzle towards the base of the plant where the fungus lives.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Blightwar kill the fungus immediately?
No, it is "fungistatic." It stops the fungus from eating and growing immediately. The lesion will stop spreading and dry up, but the spot might remain visible.
2. Can I mix Blightwar with Stem Borer medicine?
Yes, Blightwar is compatible with common stem borer insecticides like Cartap or Chlorantraniliprole.
3. Is it safe for fish in the paddy field?
Yes, Validamycin generally has low toxicity to fish compared to synthetic chemicals, but avoid direct dumping into water bodies.
4. Why should I use this instead of Hexaconazole?
Blightwar is a "resistance breaker." If you use Hexaconazole every year, the fungus gets used to it. Blightwar uses a completely different method to stop the disease.
5. Is it systemic?
It is "translaminar" (enters the leaf locally) but not fully systemic like some other chemicals. This means you must spray carefully to cover the lower parts of the plant.
