Hindustan M-45 Fungicide (Mancozeb 75% WP)
The Ultimate Broad-Spectrum Contact Fungicide for Disease Control & Crop Nutrition.
Hindustan M-45 is a trusted contact fungicide used by farmers for over 50 years to protect crops from fungal diseases like Blight, Blast, and Rust. Enriched with Manganese (Mn) and Zinc (Zn), it not only kills fungus but also acts as a micronutrient supplement, making your crops greener and healthier. It serves as a perfect "insurance spray" for comprehensive disease prevention.
Best for: Potato, Tomato, Rice (Paddy), Wheat, Chilies, and Horticultural crops.
Why Choose This Product? Key Benefits
- ⏱️Immediate Protection: Acts instantly upon contact to create a toxic barrier against fungal spores before they enter the plant.
- ?️Zero Resistance Risks: Uses a "Multi-Site" mode of action, meaning fungi cannot develop resistance to it, unlike systemic fungicides.
- ⏳Long-Lasting Legacy: The industry standard for "Crop Security," effective against all four major fungal classes (Oomycetes, Ascomycetes, etc.).
- ?️Humid Weather Specialist: Ideal for use during cloudy or humid weather when blight pressure is high (add a sticker for rainfastness).
- ?Phytotonic Effect (Greening): Supplies essential Zinc and Manganese to the plant, boosting photosynthesis and crop vigor.

How It Works: Mode of Action
Hindustan M-45 acts like a "carpet bomb" against fungi. It does not enter the plant system but stays on the surface to act as a shield.
- Surface Barrier: When sprayed, it forms a thin toxic film on the leaves and stems.
- Spore Inhibition: When a fungal spore lands on the leaf and tries to germinate (absorb moisture), it absorbs the fungicide.
- Energy Cut-off: The active ingredients disrupt the fungus's energy production (ATP), killing the spore instantly before it can infect the plant.
Note: Since it is a contact fungicide, full coverage of the plant foliage is critical for success.

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) |
|---|---|---|---|---|
| Potato / Tomato | 600 - 800 g | 200 - 300 L | 2.5 - 3.0 g | 3 - 7 Days |
| Rice (Paddy) / Wheat | 600 - 800 g | 200 L | 3.0 - 4.0 g | ~25 Days |
| Fruits (Apple, Grape) | Tree Spray Method | As Needed | 3.0 g (0.3%) | 7 - 14 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 prophylactically (preventively) before disease symptoms appear, or immediately when weather becomes cloudy/humid.
- Mixing: This is a Wettable Powder (WP). Make a slurry with a little water first, then add to the full tank. Keep the tank water agitated (stirred) to prevent settling.
- Coverage: Use a high volume of water (200L/acre) and Hollow Cone nozzles to ensure the spray covers both the top and bottom of leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray near fish ponds.
Frequently Asked Questions
1. Does Hindustan M-45 cure disease after it starts?
No, it is a contact protectant. It works best when applied before the disease spreads. For existing severe infections, tank-mix with a curative fungicide like Metalaxyl or Cymoxanil.
2. Can I mix it with other pesticides?
Yes, it is compatible with most common insecticides and fungicides (like Carbendazim/Imidacloprid). However, never mix with alkaline products like Bordeaux mixture or Lime Sulphur.
3. Why do plants look greener after spraying?
The product contains Manganese (Mn) and Zinc (Zn), which act as micronutrients, boosting photosynthesis and overall plant health.
4. Is it rainfast?
Mancozeb can wash off in heavy rain. For best results during monsoon, add a silicon-based "sticker" or spreader to the tank to help it stick to the leaves.
5. Can I use it for home gardens?
Yes, it is safe for ornamental plants and roses. Use a dosage of 2.5 to 3 grams per liter of water.
