Prospell Fungicide (Azoxystrobin 7% + Mancozeb 40% OS)
The Ultimate Dual-Action Solution for Tomato Blight Control
Prospell by Coromandel International is a technologically advanced fungicide designed specifically for high-stakes tomato farming. It combines two powerful active ingredients—Mancozeb ($40\%$) and Azoxystrobin ($7\%$)—in a unique Oil Suspension (OS) formulation.
Best For: Farmers facing yield losses due to Early Blight and Late Blight who need a solution that works even during the monsoon.
Why Choose This Product? Key Benefits
-
⏱️
Fast-Acting Control: Stops fungal attacks immediately upon contact and cures existing infections within the plant tissue.
-
🛡️
Dual-Protection Shield: Provides both a protective outer barrier (Mancozeb) and a systemic inner defense (Azoxystrobin).
-
⏳
Long-Lasting Defense: Offers extended crop protection for 10 to 14 days, reducing the need for frequent spraying.
-
🌧️
Superior Rainfastness: The Oil Suspension (OS) technology sticks to leaves better than powders, becoming rainfast in just 2–4 hours.
-
🌿
"Greening Effect" (Phytotonic): Boosts photosynthesis and delays aging, leading to greener leaves and higher quality produce.

How It Works: Mode of Action
Prospell uses a "Lock and Key" strategy to manage resistance and ensure complete disease clearance.
- Energy Blockade (Systemic): Azoxystrobin penetrates the leaf and moves through the plant's water vessels. It attacks the fungal mitochondria, cutting off the energy supply (ATP) needed for the fungus to grow.
- Multi-Site Contact Action: Mancozeb remains on the leaf surface, creating a toxic barrier that disrupts multiple chemical processes in fungal spores, preventing them from germinating.
- Kick-Back Effect: If infection has already started, the systemic action stops the fungus from spreading to new leaves.
This dual action makes it nearly impossible for fungi to develop resistance.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Tomato | Early Blight (Alternaria solani) |
| Tomato | Late Blight (Phytophthora infestans) |
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) |
|---|---|---|---|---|
| Tomato | 600 ml | 200 Litres | 3 ml | 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply preventively (before disease is severe) during the flowering to early fruiting stages for the best ROI.
- Mixing: As an Oil Suspension, Prospell can separate. Agitate (shake) well before mixing. Do not mix with highly alkaline products like Bordeaux mixture.
- Coverage: Use a hollow cone nozzle to ensure the mist penetrates the lower canopy and reaches the undersides of leaves where blight hides.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. How quickly does Prospell become rainfast?
Thanks to its Oil Suspension technology, Prospell becomes rainfast in 2–4 hours, making it ideal for the monsoon season.
2. Does Prospell help increase yield?
Yes. It inhibits ethylene production, keeping leaves greener for longer. This extends the photosynthesis period, resulting in better quality fruit and potentially higher yields.
3. Can I use this for curing established diseases?
Yes. While preventive use is best, the Azoxystrobin component has curative properties that can stop early-stage infections from spreading.
4. What is the cost per acre?
At an approximate price of ₹1,800/Litre and a dosage of 600ml/acre, the cost is roughly ₹1,080 per acre per spray. This offers a high ROI compared to potential crop loss.
5. What is the shelf life of Prospell?
The product has a shelf life of 2 years when stored in original packaging under cool, dry conditions.
