Acoreli Fungicide (Propineb 70% WP) - Disease Control with Zinc Nutrition
Acoreli by Syngenta is a broad-spectrum contact fungicide that offers dual benefits: it protects crops from fungal diseases and provides essential Zinc nutrition.
Designed as a high-quality Wettable Powder (WP), Acoreli works as a protective shield on plant surfaces. It is highly effective against major diseases like Apple Scab, Late Blight, and Downy Mildew. Unlike standard fungicides, Acoreli contains Zinc in a form that plants can easily absorb, leading to greener leaves and healthier crops.
Best For: Managing resistance, preventing disease outbreaks, and correcting Zinc deficiency in Apples, Potatoes, Rice, and Vegetables.
Why Choose This Product? Key Benefits
-
⏱️
Broad-Spectrum Protection: Effectively controls Oomycete and Ascomycete fungi (like Blights and Mildews) on contact.
-
🛡️
Resistance Management: Ideal tank-mix partner for systemic fungicides to prevent pests from developing resistance.
-
⏳
Multi-Site Action: Attacks the fungus at multiple points (respiration, energy, membrane), making it nearly impossible for disease to survive.
-
🌧️
Reliable Rainfastness: Stays effective on the leaf surface if there is no rain for 3 to 4 hours after spraying.
-
🌿
Zinc Nutrition Boost: Releases bio-available Zinc to the plant, resulting in a visible "greening effect" and better leaf quality.

How It Works: Mode of Action
Acoreli acts like a chemical shield. It does not enter the plant but stays on the surface to kill fungal spores before they can infect the crop.
- Respiration Block: It shuts down the energy production (Krebs cycle) within the fungal cells.
- Enzyme Inhibition: It targets and neutralizes essential enzymes required for fungal growth.
- Membrane Damage: It breaks down the fungal cell wall, causing the cell to leak and die.
Note: This multi-site attack makes it very difficult for fungi to develop resistance against Acoreli.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Apple | Apple Scab (Venturia inaequalis) |

| Rice | Brown Leaf Spot, Narrow Leaf Spot |
| Chilli | Dieback (Fruit Rot) |
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 (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Apple | 600 g | 200 L | 3 g | 30 Days |
| Potato | 600 g | 200 L | 3 g | 15 Days |
| Tomato | 600 g | 200 L | 3 g | 10 Days |
| Grapes | 600 - 800 g | As req. | 3 - 4 g | 40 Days |
| Rice | 600 - 800 g | 200 L | 3 - 4 g | 27 Days |
| Chilli | 1000 g | 200 L | 5 g | 10 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Use preventively (before disease appears) for best results. Re-apply every 7-10 days depending on disease pressure.
- Mixing: Premix the powder in a small bucket of water to form a smooth cream before adding it to the main tank. Maintain agitation (stirring).
- Coverage: Ensure full coverage of the leaves. Since it is a contact fungicide, it only protects the parts of the plant it touches.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid inhalation of dust during mixing.
Frequently Asked Questions
1. Does Acoreli cure disease once it has started?
No, Acoreli is a preventive fungicide. It should be applied before spores germinate to block infection. It does not cure established infections inside the plant.
2. What is the Zinc benefit of Acoreli?
Propineb contains Zinc as part of its structure. This Zinc is easily absorbed by leaves, promoting synthesis of growth hormones (auxins), leading to greener, healthier plants.
3. Is Acoreli safe for bees?
It is generally considered low-risk to bees compared to insecticides, but it is best to spray during early morning or late evening when bees are not actively foraging.
4. What if it rains after spraying?
Acoreli requires 3 to 4 hours to dry and become rainfast. If heavy rain occurs shortly after spraying, re-application may be necessary.
5. Can I mix Acoreli with other chemicals?
Yes, it is compatible with most common insecticides and fungicides (like Copper Oxychloride or Tebuconazole). Always perform a small jar test first.
