FMC Centaurus® Fungicide (Tebuconazole + Captan)
The Dual-Action Specialist for Chilli Anthracnose and Apple Scab.
Fungal diseases like Fruit Rot and Scab can destroy your harvest overnight. FMC Centaurus® is an advanced "Suspension Concentrate" (SC) fungicide designed to stop these diseases instantly. It combines two powerful chemistries—Tebuconazole and Captan—to provide both a protective shield on the outside and a deep cleaning cure on the inside.
Best For: Farmers looking for a rainfast, broad-spectrum solution that manages resistance and ensures high-quality yields in Chillies and Apples.
Why Choose This Product? Key Benefits
- ⏱️Double Action Power: Acts as both a "Systemic" cure (enters the plant to kill hidden fungus) and a "Contact" shield (protects the surface).
- ?️Resistance Breaker: Perfect for areas where older fungicides have stopped working. The multi-site action prevents fungus from adapting.
- ⏳Superior Rainfastness: The liquid SC formulation sticks to leaves better than powders, ensuring it doesn't wash off easily in rain.
- ?️Phytotoxicity Safe: Water-based formula is gentle on crops like Apple and Chilli, reducing the risk of leaf burn compared to generic powders.
- ?Eco-Friendly Profile: Safe for bees (when not sprayed directly), making it suitable for use during flowering stages.

How It Works: Mode of Action
Centaurus attacks the fungus from two angles, ensuring complete control and preventing future spread.
- Systemic Cure (Tebuconazole): Absorbed by the leaves, it travels inside the plant system to hunt down and kill established fungal infections (Ergosterol Synthesis Inhibitor).
- Surface Protection (Captan): Forms a protective chemical barrier on the leaf and fruit surface. It acts on multiple sites of the fungus, stopping spores from germinating.
- Anti-Resistance Strategy: Because it attacks the fungus in multiple ways, it is very difficult for pests to develop resistance against Centaurus.

| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli | 400 ml | 200 L | 2.0 ml | 5 Days |
| Apple (Scab) | As per tree size | High Volume | 2.5 ml | 10 Days |
| Apple (Mildew) | As per tree size | High Volume | 2.5 - 3.0 ml | 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: Apply preventatively before disease appears, or immediately upon seeing the first spots. Repeat every 10-15 days.
- Mixing: Do NOT mix with alkaline products like Lime Sulphur or Bordeaux mixture.
- Coverage: Use a Hollow Cone nozzle to create a fine mist. Ensure the undersides of leaves are fully covered.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds.
