Hitalaxyl Fungicide (Metalaxyl 8% + Mancozeb 64% WP)
The Ultimate Dual-Action Shield: Cures Infection & Protects Your Harvest
Hitalaxyl is a powerful, broad-spectrum fungicide designed to fight the toughest fungal diseases in high-value crops. By combining the systemic healing power of Metalaxyl with the protective contact layer of Mancozeb, it offers a "one-shot" solution for Downy Mildew and Late Blight. Whether you are growing grapes, potatoes, or tomatoes, Hitalaxyl stops fungus in its tracks and promotes lush, green growth thanks to its Zinc and Manganese content.

How It Works: Mode of Action
Hitalaxyl uses a smart synergistic approach to prevent fungal resistance and ensure total crop coverage.
- Systemic Cure (Metalaxyl): It penetrates the roots and leaves, traveling upwards through the plant. It inhibits protein synthesis in the fungus, stopping infection from the inside.
- Contact Shield (Mancozeb): It remains on the leaf surface, forming a toxic barrier. It kills fungal spores instantly upon contact, preventing them from germinating.
- Resistance Management: Because Mancozeb kills spores that might be resistant to Metalaxyl, this combination is excellent for long-term use without losing effectiveness.
Best used for: Downy Mildew, Late Blight, White Rust, and Damping Off.

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 (ml / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes | 1000 gm | 200 L | 5 gm | 49 |
| Potato | 1000 gm | 400 L | 2.5 gm | 49 |
| Tomato | 800 gm | 200 L | 4 gm | 49 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Black Pepper (Foot Rot): Use as Soil Drench (1.5–2.5g per Liter).
How to Apply: Best Practices
- Timing: Apply preventively (before disease appears) or immediately when the first "oil spots" are seen on leaves.
- Mixing: Use the "Slurry Method." Mix the required powder with a little water in a separate bucket to make a smooth paste, then add this to the main spray tank.
- Coverage: Ensure thorough coverage of the foliage. For potatoes/tomatoes, spray as the canopy closes to prevent blight.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhaling spray mist.
Frequently Asked Questions
1. Does Hitalaxyl cure diseases that have already started?
Yes. The Metalaxyl component has "kick-back" action, meaning it can stop fungal growth even 24 to 48 hours after infection has entered the plant.
2. Can I mix Hitalaxyl with other pesticides?
Yes, it is compatible with most common insecticides and fungicides. However, do not mix it with alkaline substances like Bordeaux mixture or Lime Sulphur.
3. What is the benefit of Zinc and Manganese in this product?
These are essential micronutrients naturally present in Mancozeb. They help correct deficiencies in the soil, leading to greener leaves and better photosynthesis.
4. Why is the waiting period (PHI) so long (49 days)?
This ensures that all chemical residues have degraded to safe levels before you harvest. This is especially important for export crops like grapes to meet international safety standards.
5. How does it help with resistance management?
Fungi often become resistant to single-chemical sprays. Hitalaxyl mixes two different chemicals (Systemic + Contact), making it very difficult for the fungus to survive or develop resistance.
