How It Works: Mode of Action
Hindustan M-45 acts like a "carpet bomb" against fungal cells, ensuring no survivors. It does not enter the plant system but stays on the leaf to kill spores before they germinate.
- Surface Barrier: Creates a protective coating on leaves, stems, and fruits.
- Metabolic Disruption: Once a spore absorbs the chemical, it simultaneously blocks respiration (breathing) and lipid metabolism.
- Energy Cut-off: It stops ATP production, starving the fungus of energy and killing it instantly.
Because it attacks multiple systems at once, fungi cannot mutate to resist it.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Potato & Tomato | Late Blight, Early Blight, Buck Eye Rot, Leaf Spot |

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 / Wheat | 600 - 800 g | 200 - 250 L | 2.5 - 3.0 g | 25 - 30 Days |
| Chili / Vegetables | 600 - 800 g | 200 - 300 L | 2.5 g | 5 - 7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage is in grams (g) as this is a Wettable Powder.
How to Apply: Best Practices
- Timing: Use "Prophylactically" (Preventively). Start spraying before disease appears, especially when weather is cloudy or humid.
- Mixing: M-45 is a suspension. Shake the spray tank continuously to prevent the powder from settling at the bottom.
- Coverage: Use high water volume. Since it is a contact fungicide, it only protects the parts of the plant it touches. Ensure full coverage of both sides of the leaf.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds.
Frequently Asked Questions
1. Can I mix Hindustan M-45 with other chemicals?
Yes, it is compatible with most insecticides and fungicides like Metalaxyl and Carbendazim. However, do not mix with alkaline products like Bordeaux Mixture or Lime Sulphur.
2. Does it cure disease after it has started?
M-45 is primarily a protectant. For established infections, mix it with a systemic curative fungicide (like "HPM Stuff") to stop the spread and kill the fungus.
3. Why do my crops look greener after spraying?
This is the "Phytotonic Effect." Hindustan M-45 supplies Manganese and Zinc, which correct micronutrient deficiencies and boost photosynthesis.
4. Is it safe for soil?
Yes, Mancozeb breaks down rapidly in soil (2-8 days) and does not harm groundwater. However, it is toxic to Trichoderma, so allow a 7-day gap between applying biologicals and M-45.
5. What is the shelf life of the product?
Under dry storage conditions, it remains stable for up to 2 years. Keep away from moisture to prevent degradation.
