Shan Fungicide (Azoxystrobin 11% + Tebuconazole 18.3% w/w SC)
The "Double-Lock" Protection for Rice, Chilli, and Vegetables with Added Zinc & Manganese.
Shan is a premium broad-spectrum fungicide by Nichino India that offers complete disease control. It combines two powerful chemistries—Azoxystrobin and Tebuconazole—in a superior Suspension Concentrate (SC) formulation.
Why it stands out: Unlike ordinary fungicides, Shan is enriched with Zinc (Zn) and Manganese (Mn). This unique "Nutri-Protection" technology not only kills the fungus but also boosts plant health, resulting in a visible "Greening Effect" and higher yields.
Why Choose This Product? Key Benefits
-
⏱️
Rapid "Double-Lock" Action: Stops disease immediately. It works preventively (before infection) and curatively (after infection) to clean your crop.
-
🛡️
Nutri-Protection Technology: Contains Zinc and Manganese to correct micronutrient deficiency and boost photosynthesis.
-
⏳
Systemic & Long-Lasting: Moves within the plant (translaminar and acropetal action) to protect new leaves that grow after spraying.
-
🌧️
Superior Rainfastness: The advanced SC formulation sticks to waxy leaves (like Onion and Chilli) and resists washing off by rain.
-
🌿
Phytotonic "Greening" Effect: Delays aging of leaves, keeps the crop green longer, and improves grain filling and fruit quality.

How It Works: Mode of Action
Shan utilizes a synergistic dual-mode action to ensure no fungal spore survives.
- Energy Block (Azoxystrobin): It penetrates the fungal cells and blocks their energy production (ATP) in the mitochondria. This stops the fungus from breathing and prevents spores from germinating.
- Wall Destruction (Tebuconazole): It inhibits Ergosterol biosynthesis. Without Ergosterol, the fungal cell walls collapse, leading to the death of the fungus even after it has entered the plant.
- Plant Recovery (Zn + Mn): While the chemicals fight the fungus, the added micronutrients stimulate the plant's recovery, enhancing photosynthesis and growth hormones.
This combination makes it highly effective against difficult diseases like Sheath Blight, Anthracnose, and Downy Mildew.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Chilli | Fruit Rot (Anthracnose), Powdery Mildew, Die-back |
| Rice (Paddy) | Sheath Blight, Blast, Dirty Panicle |
| Onion | Purple Blotch, Stemphylium Blight |
| Tomato & Potato | Early Blight, Late Blight |
| Wheat | Yellow Rust (Stripe Rust), Powdery Mildew |
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) |
|---|---|---|---|---|
| Chilli | 240 ml | 200 L | 1.2 ml | 5 Days |
| Rice (Paddy) | 300 ml | 200 L | 1.5 ml | 30 Days |
| Onion | 300 ml | 200 L | 1.5 ml | 7 Days |
| Tomato/Potato | 300 ml | 200 L | 1.5 ml | 5 Days |
| Wheat | 300 ml | 200 L | 1.5 ml | 35 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 preventively or at the very first sign of disease. For Rice, apply at the Booting stage. For Chilli, apply from flowering to fruit setting.
- Mixing: Conduct a physical compatibility test (Jar Test) before mixing with other chemicals. Avoid mixing with highly alkaline products like Bordeaux mixture.
- Coverage: Use a Hollow Cone nozzle for the best coverage. Ensure the spray reaches the lower leaves and underside of the canopy.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can Shan be mixed with insecticides?
Yes, Shan is generally compatible with common insecticides like Imidacloprid or Lambda-cyhalothrin. This allows you to control pests (like Thrips) and diseases (like Fruit Rot) in a single spray.
2. Does Shan help increase crop yield?
Yes. Apart from disease control, the Zinc and Manganese in Shan promote nitrogen assimilation and reduce ethylene production. This keeps the leaves green longer (Greening Effect), leading to better grain filling and higher yields.
3. What is the dosage for Chilli Fruit Rot?
For Chilli, the recommended dose is 240 ml per acre mixed in 200 liters of water. It is highly effective against Fruit Rot (Anthracnose) and Powdery Mildew.
4. Is Shan effective in rainy weather?
Yes. Shan is a high-quality Suspension Concentrate (SC). Once the spray dries on the leaf (which happens quickly), it becomes rainfast and won't easily wash away, ensuring protection even during the monsoon.
5. Can I use Shan for Drone spraying?
Yes, Shan is suitable for drone application due to its fine particle size which prevents nozzle clogging. Ensure proper calibration to deliver the active ingredient effectively.
