Tebuconazole 10% + Sulphur 65% WG (Systemic & Contact Fungicide)
The "Double-Engine" Formula: Powerful Disease Control + Plant Nutrition.
This advanced Combi-Product by Insecticides (India) Ltd (IIL) brings together two powerful forces: Tebuconazole (a systemic hunter) and Sulphur (a contact shield). Designed for modern Indian agriculture, it offers a complete solution for hard-to-control diseases like Powdery Mildew and Fruit Rot while simultaneously nourishing your crop with essential Sulphur.
Note on Branding: While IIL is a registered manufacturer of this chemistry, please note that the brand name "Hana" refers to their PGR product (Paclobutrazol). This fungicide is typically marketed under brands like Radostar or sold as a generic technical formulation.
Why Choose This Product? Key Benefits
-
⏱️
Triple Action Power: Acts as a Fungicide, a Miticide (kills mites), and a Micronutrient (Sulphur) all in one spray.
-
🛡️
Preventive & Curative: The Sulphur creates a shield on the leaf surface, while Tebuconazole enters the plant to kill hidden fungus.
-
⏳
WG Technology: The "Water Dispersible Granule" formulation ensures no dust, easy mixing, and uniform coverage without clogging nozzles.
-
🌧️
Resistance Fighter: Combining two different modes of action makes it very difficult for fungi to develop resistance.
-
🌿
Phytotonic Effect: The 65% Sulphur content corrects deficiency, leading to greener leaves and better photosynthesis.

How It Works: Mode of Action
This fungicide uses a synergistic approach to eliminate disease from both the inside and outside.
- Systemic Entry (Tebuconazole): Absorbed by the leaves, it travels efficiently through the xylem (water vessels) to reach new growth and kill fungal mycelium hiding inside plant tissues.
- Contact Barrier (Sulphur): It spreads across the leaf surface, disrupting fungal respiration and preventing new spores from germinating.
- Multi-Site Inhibition: While Tebuconazole blocks sterol biosynthesis (cell wall building), Sulphur disrupts energy production, making it nearly impossible for fungi to survive.
Bonus: The sulphur fumes also act as a deterrent to mites (Acaricidal property).
Target Crops & Pests
| Crop | Target Pest(s) |

| Chilli | Powdery Mildew, Fruit Rot (Anthracnose) |

| Others* (Field Use) | Yellow Rust (Wheat), Tikka Disease (Groundnut) |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli | 500 g | 200 L | 2.5 g | 5 Days |
| Soybean | 500 g | 200 L | 2.5 g | 26 Days |
| General | 500 g | 200 L | 2.5 g | Refer Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply prophylactically (before disease appears) or immediately at the first sign of Powdery Mildew or Leaf Spots.
- Mixing: Add the required quantity of granules to a small amount of water to make a slurry, then add to the main tank. It disperses instantly.
- Coverage: Ensure full coverage of the foliage. The systemic action helps, but contact sulphur needs to hit the target.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during the hottest part of the day.
Frequently Asked Questions
1. Is this product the same as "Hana"?
No. "Hana" is a Plant Growth Regulator (Paclobutrazol) used for flowering in Mango. This product is a Fungicide (Tebuconazole + Sulphur). Do not confuse them as they have very different effects.
2. Can I mix this with insecticides?
Yes, it is generally compatible with common insecticides like Imidacloprid. However, do not mix with oil-based formulations or alkaline Bordeaux mixture as Sulphur can cause burning.
3. Does it help with mites?
Yes. The high Sulphur content (65%) provides significant suppression of mites (Acaricidal action), often eliminating the need for a separate mite spray in mild infestations.
4. What is the benefit of WG formulation over powder?
WG (Water Dispersible Granules) are dust-free, safer to handle, and dissolve much better in water, ensuring the nozzle doesn't clog and the plant gets an even dose.
5. Why do my plants look greener after spraying?
This is the "Phytotonic Effect." Sulphur is a key nutrient for chlorophyll production. Spraying this formulation corrects sulphur deficiency, making leaves greener and healthier.
