Aliette Fungicide (Fosetyl-Aluminium): The Systemic Immunity Booster
Defeat Downy Mildew and Root Rot with India's only "Ambimobile" fungicide that protects crops from the inside out.
Aliette® is a legendary systemic fungicide widely used in Indian agriculture for high-value crops like Grapes, Cardamom, and Citrus. Unlike ordinary sprays that only coat the leaf, Aliette absorbs into the plant and travels both up and down (Ambimobile). This allows it to cure hidden root infections even when sprayed on leaves. It acts as an "immunity booster," triggering your crop's natural defense system to fight off deadly fungal diseases.
Note on Brand: While Aliette is a proprietary product of Bayer CropScience, it is widely available through the extensive distribution network of partners like Rallis India, making it easily accessible to farmers across the country.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Absorption: Absorbs into the plant system within 1 hour, minimizing wash-off during monsoons.
-
🛡️
Dual Protection (Root & Leaf): Unique ability to travel downwards (Basipetal) to protect roots from rotting, even when sprayed on foliage.
-
⏳
Long-Lasting Defense: Provides extended protection for 14 to 21 days, reducing the need for frequent spraying.
-
🌧️
Rainfast Solution: Ideal for the rainy season as it locks inside the plant tissue quickly.
-
🌿
Immunity Booster: Activates Systemic Acquired Resistance (SAR), effectively "vaccinating" the plant against future attacks.

How It Works: Mode of Action
Aliette fights fungus in three unique ways, ensuring total crop safety:
- Direct Attack: It enters the fungal cells and stops them from growing or producing new spores (Fungistatic action).
- Self-Defense Trigger (SAR): It signals the plant to produce its own natural antibiotics (phytoalexins) and thicken its cell walls, making it harder for diseases to penetrate.
- Two-Way Movement: Unlike most fungicides that only move up, Aliette moves both Up (Acropetal) and Down (Basipetal) through the plant's vascular system, reaching root tips and new leaves simultaneously.
This multi-site action makes it very difficult for fungi to develop resistance.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Grapes | Downy Mildew (Plasmopara viticola) |
| Cardamom | Azhukal (Capsule Rot), Rhizome Rot, Damping Off |
| Citrus (Orange, Lime) | Foot Rot, Gummosis, Citrus Decline (Phytophthora spp.) |
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 (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Grapes | 800 g – 1000 g | 400 L | 2.0 – 2.5 g | 30 Days |
| Cardamom | 1200 g (1.2 kg) | 400 L | 3.0 g | 90 Days |
| Citrus | Varies by Tree Size | As required | 2.5 g | -- |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Best applied preventively or at the very early stage of disease. For Grapes, start at the 3-5 leaf stage.
- Mixing: WARNING: Do NOT mix Aliette with Copper-based fungicides (like Bordeaux mixture) or liquid fertilizers. It will burn the leaves. Keep a 14-day gap between Aliette and Copper sprays.
- Coverage: Ensure full canopy coverage. For root rot, spraying the leaves is enough as the chemical travels down to the roots.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Is Aliette a Bayer product or Rallis product?
Aliette is manufactured by Bayer CropScience. However, in India, it is often sold and distributed through Rallis India's extensive dealer network, leading to common association between the two brands.
2. Can I mix Aliette with Copper Oxychloride?
NO. Mixing Aliette with any copper fungicide causes severe phytotoxicity (leaf burn). Always maintain a 14-day gap between using Aliette and any copper product.
3. How long does it take to absorb?
Aliette is absorbed into the plant leaves within 1 hour. After this, it is rainfast and will not wash away with rainfall.
4. Does it cure root rot?
Yes. Because Fosetyl-Al travels downwards from the leaves to the roots (basipetal movement), it is highly effective against soil-borne root rots in Citrus and Cardamom.
5. Is it safe for export grapes?
Yes, Aliette is widely accepted for export grapes, provided you strictly follow the PHI (Pre-Harvest Interval) of 30 days to meet European MRL standards.
