Satsuma M-45 (Mancozeb 75% WP): Broad-Spectrum Contact Fungicide
The ultimate "Multi-Site" shield against Blight, Rust, and Mildew for Indian Agriculture.
Satsuma M-45 is a high-quality contact fungicide containing Mancozeb 75% WP. Unlike expensive systemic options, Satsuma M-45 acts as a powerful protective layer on crop leaves, preventing fungal spores from entering. Beyond disease control, it provides a "Green Effect" by supplying essential Manganese and Zinc nutrition to your crops, making it a dual-action solution for healthier yields.
Best for: Potato, Tomato, Paddy, Wheat, and Horticulture crops.
Why Choose Satsuma M-45? Key Benefits
- ⏱️Immediate Contact Action: Acts instantly upon contact with fungal spores, neutralizing them before they can infect the plant tissue.
- ?️Zero Resistance Risk: Uses a "Multi-Site" mode of action. Fungi cannot easily develop resistance to it, making it perfect for long-term use.
- ⏳Cost-Effective Protection: A highly affordable "workhorse" fungicide that delivers excellent ROI, especially for smallholder farmers.
- ?️Controls Humidity-Loving Fungi: Specifically effective against Late Blight and Downy Mildew which thrive in rainy, foggy weather.
- ?The "Green Effect": Contains Zinc (Zn) and Manganese (Mn) which correct micronutrient deficiencies and boost photosynthesis.

How It Works: Mode of Action
Satsuma M-45 is a broad-spectrum contact fungicide. It does not enter the plant but stays on the leaf surface to form a chemical barrier.
- Contact Poison: When fungal spores land on the leaf and try to germinate, they absorb the Mancozeb particles.
- Metabolic Disruption: The active ingredient targets the amino acids and enzymes within the fungus, stopping its respiration and energy production.
- Multi-Site Attack: It attacks the fungus at multiple points simultaneously (respiration, cell membrane, etc.), making it nearly impossible for the fungus to survive or mutate.
Note: Because it is a contact fungicide, it must be applied before the disease enters the plant tissue.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Potato & Tomato | Late Blight, Early Blight, Leaf Spot, Buckeye Rot |
| Paddy (Rice) & Wheat | Blast, Brown Leaf Spot, Brown Rust, Black Rust |
| Fruits (Apple, Grape, Banana) | Scab, Downy Mildew, Anthracnose, Sigatoka Leaf Spot |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Coverage is King!
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/L | 3 – 5 Days |
| Paddy / Wheat | 600 – 800 g | 300 L | 2.0 – 2.5 g/L | 25 – 30 Days |
| Grapes / Apple | Based on canopy | High Volume | 2.0 – 3.0 g/L | 30+ 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 (before disease symptoms appear). Start sprays immediately upon "Blight Warnings" or when weather becomes cloudy/humid.
- Mixing: Do not mix with alkaline products like Bordeaux Mixture or Lime Sulphur. Add a "Sticker" during rainy season to prevent wash-off.
- Coverage: Use high water volume (minimum 300L/acre for field crops). Ensure both upper and lower sides of leaves are coated.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not inhale the dust.
Frequently Asked Questions
1. Is Satsuma M-45 a systemic fungicide?
No, it is a contact fungicide. It stays on the leaf surface and kills spores before they enter the plant. It does not move inside the plant.
2. Can I use it to cure a disease that has already spread?
Satsuma M-45 is best used for prevention. If the disease is already established inside the plant, tank-mix it with a systemic curative fungicide (like Metalaxyl or Carbendazim) for best results.
3. Is it compatible with other chemicals?
Yes, it is compatible with most common insecticides and fungicides. However, never mix it with alkaline substances like Lime Sulphur or Bordeaux Mixture.
4. What happens if it rains after spraying?
Heavy rain can wash the powder off the leaves. Use a silicon-based sticker/spreader to improve rainfastness. If it rains heavily immediately after spraying, you may need to re-apply.
5. Does it provide nutrition to the crop?
Yes! It contains Manganese (Mn) and Zinc (Zn), which helps in greening the leaves and improving overall plant health.
