Blasil Fungicide (ADAMA): The Ultimate Super Blasticide for Rice
Blasil by ADAMA is a highly advanced, dual-action fungicide designed specifically to protect your rice crop from devastating blast diseases. Known globally as a "Super Blasticide," it delivers unmatched, long-lasting control against leaf, node, and neck blast.
By combining two powerful active ingredients in a premium suspo-emulsion (SE) formula, Blasil provides immediate curative action to stop existing infections and systemic preventative defense to protect new growth. This guarantees better grain quality, heavier yields, and higher market value for your harvest.
Protect your paddy from sterile panicles and whiteheads with Blasil’s fast-acting, rainfast technology!
Why Choose This Product? Key Benefits
- ⏱️Fast & Long-Lasting Protection: Provides an immediate cure for existing fungal infections while moving systemically to shield new leaves and emerging panicles.
- 🛡️Dual Action Power: Combines a Melanin Biosynthesis Inhibitor (preventative) and a Sterol Biosynthesis Inhibitor (curative) to attack the disease from multiple angles and prevent resistance.
- ⏳Rainfast Innovation: Rapidly absorbs into the plant tissue within just 1 to 2 hours, ensuring your crop stays protected even if it rains shortly after spraying.
- 🌧️Premium SE Formulation: The advanced Suspo-Emulsion technology contains fewer harsh solvents. It spreads perfectly over the waxy rice leaves without causing chemical burns or stress.
- 🌿Superior Grain Quality: By protecting the plant's vascular system, Blasil ensures heavy, fully-filled, and shiny rice grains that suffer less breakage during milling.

How It Works: Mode of Action
Blasil uses a highly synergistic combination of two active ingredients to completely shut down the rice blast disease cycle:
- Tricyclazole (The Shield): Acts as a preventative "anti-penetrant." It stops the fungus from building a strong, melanin-fortified wall. Without this wall, the disease cannot physically punch through the rice leaf and starves on the surface.
- Prochloraz (The Destroyer): Acts as the immediate cure. It penetrates the plant tissue (translaminar movement) and destroys the cell membranes of any fungus that has already infected the crop, stopping its growth instantly.
- Systemic Circulation: Once applied, Blasil moves steadily upward and outward through the plant's vascular system, actively guarding new leaves and developing grain heads that weren't even exposed to the original spray.

| Rice (Paddy) | Node Blast |
| Rice (Paddy) | Neck Blast |
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 (Early Tillering) | 400 ml | 200 L | 2 ml | 40 Days |
| Rice (Booting Stage) | 400 ml | 200 L | 2 ml | 40 Days |
| Rice (Heading Stage) | 400 ml | 200 L | 2 ml | 40 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For the highest yield protection, apply Blasil right before the "booting" stage (55-85 days after transplanting). This prevents devastating neck blast before the panicle emerges.
- Mixing: Dilute 2 ml of Blasil liquid per 1 litre of water. For a standard 15-litre knapsack sprayer, mix exactly 30 ml per tank.
- Coverage: Spray evenly across the canopy. Do not apply right before heavy rainfall or on extremely windy days to avoid chemical runoff.
- Safety: Always wear PPE (full-body coveralls, chemical-resistant gloves, and a face shield). Wash hands thoroughly after use. Never spray near rivers, ponds, or blooming flowers, as it is highly toxic to fish and bees.
Frequently Asked Questions
1. When is the most critical time to spray Blasil?
The most crucial window is during the "booting stage" (around 55-85 days after transplanting). Applying it preventatively here completely shields the panicle neck, preventing total crop loss from neck blast.
2. How much Blasil should I use per tank?
Mix 30 ml of Blasil in a standard 15-litre knapsack spray tank (2 ml per litre of water). You will need roughly 400 ml of product to cover one entire acre.
3. Is it safe to export rice treated with Blasil?
Yes, but you MUST follow the 40-Day Pre-Harvest Interval (PHI). You are legally required to stop spraying Blasil at least 40 days before harvest to ensure chemical residues drop below international export limits.
4. What happens if it rains after spraying?
Blasil is highly rainfast. Because of its advanced suspo-emulsion (SE) liquid formulation, it absorbs directly into the plant tissue within 1 to 2 hours, making it highly resistant to rain wash-off.
5. Does Blasil actually improve the harvest quality?
Yes! By completely stopping node and neck infections, Blasil ensures that water and nutrients flow smoothly to the rice grains. This results in heavier, shinier grains and significantly less breakage during the milling process.
