How It Works: Mode of Action
Satsuma M-45 operates as a Multi-Site Inhibitor. Unlike systemic fungicides that attack one specific part of the fungus, Mancozeb attacks multiple vital systems simultaneously.
- Contact & Activation: When the spray lands on the leaf and meets moisture (rain or dew), it releases active compounds called isothiocyanates.
- Enzyme Disruption: These compounds target amino acids and enzymes within the fungal cell, shutting down respiration and energy production (ATP).
- Germination Block: It kills the fungal spores before they can germinate and penetrate the leaf surface, effectively "locking the door" against disease.
Note: Because it attacks multiple sites, fungi cannot mutate fast enough to become resistant.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Potato & Tomato | Late Blight, Early Blight, Buckeye Rot, Leaf Spot |
| Paddy (Rice) | Blast (Leaf Blast), Brown Leaf Spot |

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Satsuma M-45 relies on good coverage, so use plenty of water.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (gm / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Potato / Tomato | 600 – 800 g | 300 L | 2.0 - 2.5 g | 3 - 5 Days |
| Paddy / Wheat / Maize | 600 – 800 g | 300 L | 2.0 - 2.5 g | 25 - 30 Days |
| Grapes / Apple | Varies (See label) | Ensure Coverage | 2.0 - 3.0 g | 30+ Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting to ensure food safety.
How to Apply: Best Practices
- Timing: Use Prophylactically (Preventatively). Start spraying before you see the disease, or immediately upon receiving a weather warning (cloudy/humid). Repeat every 7-10 days.
- Mixing: Do NOT mix with alkaline products like Bordeaux Mixture or Lime Sulphur, as this destroys the chemical. Always test water pH; ideal pH is 5.5–6.5.
- Coverage: Use high water volume (300 Liters/acre for field crops). Ensure the nozzle creates a fine mist to coat both upper and lower leaf surfaces. Add a sticker/spreader during rainy seasons.
- Safety: Always wear PPE (gloves, mask, goggles). Avoid inhaling the dust during mixing. Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Satsuma M-45 with other pesticides?
Yes, it is generally compatible with common insecticides like Imidacloprid and fungicides like Carbendazim or Metalaxyl. Do not mix with alkaline substances.
2. Does it cure the disease if the plant is already rotting?
No. Satsuma M-45 is a contact preventative. It stops new infections but cannot cure established internal infections. Use it early to prevent the disease.
3. What is the "Green Effect"?
Mancozeb contains Manganese and Zinc. These are essential micronutrients that help the plant produce chlorophyll, leading to greener, healthier leaves.
4. What happens if it rains after spraying?
If it rains heavily (>25mm) immediately after spraying, the product may wash off. Using a silicon-based sticker helps it stick better. Re-application may be necessary after heavy rains.
5. What is the shelf life of the product?
If stored in a cool, dry place away from moisture and heat, the product is stable for 2 years from the date of manufacture.
