Item description
Rallis Master Fungicide (Metalaxyl 8% + Mancozeb 64% WP)
The Ultimate Dual-Action Protection Against Blight and Downy Mildew
Rallis Master is a trusted broad-spectrum fungicide brought to you by Rallis India Ltd (A Tata Enterprise). It combines the power of two active ingredients to provide complete crop protection. It works inside the plant to cure infections and stays on the surface to prevent new attacks.
Best Used For: Controlling Late Blight in Potatoes/Tomatoes, Downy Mildew in Grapes, and Damping Off in nurseries.
Why Choose This Product? Key Benefits
- ⏱️ Rapid Action: Absorbs into the plant system within 30 to 60 minutes, meaning rain won't wash it away easily.
- ?️ Double Protection: Acts as a shield on the outside (Contact) and a medicine on the inside (Systemic).
- ⏳ Curative Power: Stops fungal growth even if applied 24-48 hours after the infection begins (Kick-back action).
- ?️ Prevents Resistance: The unique 2-in-1 formula ensures fungus cannot easily adapt or become resistant to the spray.
- ? Greener Crops (Phytotonic): Enriched with Zinc and Manganese that act as nutrients, making leaves visibly greener and healthier.

How It Works: Mode of Action
Rallis Master uses a "Double-Lock" mechanism to ensure disease control:
- Systemic Control (Inside): The Metalaxyl enters the plant system and stops the fungus from growing or spreading internally.
- Contact Shield (Outside): The Mancozeb remains on the leaf surface, killing fungal spores instantly upon contact.
- Multi-Site Action: It disrupts multiple energy processes in the fungus, making it nearly impossible for the disease to survive.

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) |
|---|---|---|---|---|
| Grapes | 800g - 1000g | 200 - 400 L | 2.5 g/L | 49 Days |
| Potato / Tomato | 1000g (1 kg) | 300 - 400 L | 2.5 g/L | 49 Days |
| Mustard | 1000g (1 kg) | 300 - 400 L | 2.5 g/L | 56 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Dosage values are approximate based on CIBRC hectare recommendations.
How to Apply: Best Practices
- Timing: Apply preventively (before disease starts) or immediately when you see the first "oil spot" or blight symptom.
- Mixing: Do not dump the powder directly into a full tank. Mix the powder with a little water first to make a smooth paste (slurry), then add to the main tank.
- Coverage: Ensure you spray the undersides of leaves where fungi hide. Use adequate water volume.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Rallis Master a systemic fungicide?
Yes, it is both systemic and contact. The Metalaxyl
(8%) component is systemic and enters the plant, while Mancozeb
(64%) acts as a contact protectant.
2. Can I use this for Late Blight in Potatoes?
Absolutely. Rallis Master is specifically designed to
control Late Blight and protect the tubers from rotting in
storage.
3. What is the dose per 15-liter pump?
At a standard rate of 2.5g/Litre, you should use
approximately 35g to 40g of Rallis Master per 15-liter spray tank.
4. Does it make the crops greener?
Yes. The Mancozeb in the formula contains Zinc and
Manganese, which correct micronutrient deficiencies and lead to a
"Phytotonic" greening effect.
5. What happens if it rains after spraying?
The Metalaxyl component absorbs into the plant within
1 hour. If it rains after this period, the systemic protection
remains active inside the plant.
