Natraj Fungicide (Azoxystrobin 11.5% + Mancozeb 30% WP)
Advanced Dual-Action Crop Protection by HPM Chemicals
Secure your harvest with Natraj, a premium broad-spectrum fungicide designed for modern agriculture. Unlike standard fungicides, Natraj combines two powerful active ingredients—Azoxystrobin and Mancozeb—to provide both internal (systemic) and external (contact) protection.
Note: This is a specialized agricultural product manufactured by HPM Chemicals & Fertilizers Ltd. and is distinct from the Nataraj stationery brand.

How It Works: Mode of Action
Natraj utilizes a unique synergistic formula that attacks fungi in two distinct ways, ensuring no escape for the disease.
- Systemic Power (Azoxystrobin): Absorbed by roots and leaves, it travels through the plant (xylem) to kill fungus hiding inside the tissues.
- Contact Shield (Mancozeb): Remains on the leaf surface, acting as a "protective coat" that kills fungal spores upon contact.
- Nutritional Value: The Mancozeb component supplies essential micronutrients (Manganese and Zinc), promoting healthier, greener leaves.
This dual approach ensures that existing infections are stopped (Curative) and new infections are blocked (Preventive).

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" recommended on the official product leaflet for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tomato / Vegetables | Refer to Leaflet | 200 L | ~2 - 2.5g | 3-5 Days |
| Field Crops (Rice, Soyabean) | Refer to Leaflet | 150 - 200 L | ~2g | 15-20 Days |
| Fruit Crops | Refer to Leaflet | Variable | ~2g | Check Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Always confirm exact dosage with the enclosed product leaflet.
How to Apply: Best Practices
- Timing: Apply proactively when disease symptoms first appear or when weather conditions favor disease (cloudy/humid).
- Mixing: Mix the Wettable Powder (WP) with a small amount of water to make a paste before adding to the main tank.
- Coverage: Ensure uniform spraying over the leaves; use a knapsack or power sprayer for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This is a Class 9 regulated substance.
