Hexastop Fungicide (Thiophanate Methyl 70% WP)
The "Green Triangle" Safety Solution for Healthy, Spot-Free Crops.
Hexastop by Coromandel is a broad-spectrum systemic fungicide designed to protect your high-value crops like Apples, Grapes, and Papayas. It works from the inside out to fight fungal diseases and provides a unique "Phytotonic" effect that makes leaves greener and healthier.
Best For: Controlling Scab in Apples, Powdery Mildew in Papaya/Grapes, and Anthracnose in Vegetables.
Why Choose This Product? Key Benefits
-
⏱️
Double Action (Preventive & Curative): Stops disease before it starts and cures infections that are already inside the plant.
-
🛡️
Systemic Protection: Absorbed by leaves and roots, it travels through the plant's system (Xylem) to protect even new growth that wasn't sprayed.
-
⏳
Long-Lasting Control: Remains active within the plant system for an extended period, reducing the need for frequent sprays.
-
🌧️
Rainfast Absorption: Quickly absorbed into the plant tissue, making it less likely to wash off during unexpected rains.
-
🌿
Phytotonic Effect (Greening): Contains Sulfur, which boosts chlorophyll production, making your crop look greener, fresher, and more vigorous.

How It Works: Mode of Action
Hexastop acts as a "pro-drug," meaning it transforms after application into an even more powerful fungus-killer called Carbendazim.
- Systemic Entry: It enters the plant through roots or leaves and travels upward through the water vessels (xylem).
- Growth Stop: It targets the cell division process (mitosis) of the fungus. Specifically, it binds to a protein called beta-tubulin.
- Fungal Death: By blocking cell division, the fungus cannot grow, produce spores, or spread, effectively starving the infection.
Note: Because it attacks a specific site, always rotate Hexastop with other fungicides to prevent resistance.
Target Crops & Pests

|---|---|
| Apple | Scab (Venturia inaequalis) |
| Papaya & Grapes | Powdery Mildew, Anthracnose, Rust |
| Bottle Gourd (Cucurbits) | Anthracnose |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Papaya / Grapes | 286 g | 300 - 400 L | ~0.7 - 1.0 g | - |
| Apple | 286 g | 300 - 400 L | ~0.7 - 1.0 g | 3 - 14 |
| Bottle Gourd | 572 g | 300 - 400 L | ~1.5 - 2.0 g | 24 |
*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 appears) or at the very first sign of spots for the best curative effect.
- Mixing: Since this is a powder, pre-mix the required dose in a small bucket of water to form a smooth slurry (paste) before adding it to the main spray tank.
- Coverage: Ensure uniform spray coverage. While it is systemic, good coverage ensures faster uptake.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Hexastop with other chemicals?
Yes, it is compatible with most insecticides and fungicides. However, do not mix with alkaline products like Bordeaux mixture, Lime Sulphur, or Copper fungicides, as they will destroy the medicine.
2. What is the "Phytotonic Effect"?
The Thiophanate Methyl molecule contains Sulfur. As it breaks down, it releases this sulfur, which the plant uses to produce amino acids and vitamins, resulting in a visibly greener and healthier crop.
3. Is Hexastop safe for export crops?
Hexastop has a specific residue limit. For export crops (especially grapes for the EU), check current strict regulations as Thiophanate Methyl residues are monitored closely.
4. How many times can I spray Hexastop?
Limit use to 2-3 times per season. Always rotate with a fungicide from a different group (like Mancozeb) to prevent the fungus from becoming resistant.
5. What happens if it rains after spraying?
Hexastop is absorbed quickly into the plant system. Once absorbed (usually within a few hours), it is rainfast and will not wash away easily.
